XPATH woes

I am trying to execute some basic XPATH statements of the form
"sum(/root/transactions/lineitem/amount)"
The database table in question has a few Kilobytes of XML stored in a XMLType column and about 10000 rows in the table. If I attempt to use XMLQuery to execute this XPath, then the session just seems to hang. I left it running overnight and it was still running the next day!!! If I delete most of the rows in table and just leave 10 or 20 rows then XMLQuery returns a result. But the system I'm working on needs to support millions of rows!
I don't need all the flexibility of XQuery so I tried using extractValue instead of XMLQuery which fails with the following error:
ORA-31012: Given XPATH expression not supported
I'm using Oracle 10g Release 2. Does anyone have any ideas on how I can execute a few simple XPath expressions against large tables? This works beautifully in SQL Server 2005!

A stream or a reader permits only sequential access. Once you have read it, that's the end. You can't do anything with it after that. But a DOM permits random access. You can read through it from start to finish, you can jump into the middle, you can read backwards, whatever you like. You can do that indefinitely.Sorry, DrClap, but I have to say this: You are plain wrong. Streams can of course be reused. That's what the mark and reset mechanism is used for.
Back to the topic: Any method closing a stream passed inside the method is nothing more but establishing a bad bad ... BAD side-effect.

XPath API woes

I'm trying to parse an XML document using the Actionscript 2
XPath API. In one place I am using this as my xpath:
presentation/content[@contentName='wellness']/section[@sectionName='Nutrition/Weight']'
It fails when I use a slash in the "sectionName" attribute,
when I remove the slash in the XML file and change the xpath
accordingly it works fine. This XML is being generated for me, so I
really have no choice in the matter, the slash has to stay. Is
there something I can do to get around this problem?

Mainly :
- Speed,
- Compact : 100Ko,
- Pluggable kit for custom node usage,
- JDK 1.1,
- Featuring like lowercase/uppercase for HTML.
Hope it replies,

Continual Mac woes (no question, just a rant)

It's Tuesday, and I am having terrible problems with my Mac. But then, why should Tuesday be different from any other day of the week.
Here is a typical day for me. The computer appears to be working OK. I need to watch a DVD for my work. I turn on DVD player, and put one in. The machine can't read the disc. It clicks and whirls, but the icon does not show up on the desktop. Meanwhile, so distressed is the machine that it freaks out. What was up until now was a fluidly operating machine suddenly reverts back to its old ways (i.e., its ways of two days ago). The hold ups and spinning pinwheels begin to eat of hours of my work day. (Remember the old days when computers made life easier?) The machine becomes sticky, gummy. Oh, I can move the curser and it seems to work for a second but then gets stuck in the dock, which explodes in icons and then freezes for five minutes. Yes. Five minutes.
Would love to use Force Quit, but the cursor is spinning, and nothing is responding. Funny about that old Mac. You can't force quit Force Quit. I guess I need to leave it open all the time.
Of course, FQ usually works on Safari. I have never just "quit" Safari. It always requires Force Quit, otherwise I can't turn off my computer. It stalls shut down.
Now I have a DVD trapped in there and can't get it out. [But I just got an answer from another posting.]
In the old macs, there used to be a pin hole you could stick a needle into ... can't find one on my flatpanel iMac.
I bought my Apple flat panel iMac in August of 2002. Yes, I know that that is a long time to have a computer, but I am not rich nor attached to a corporation that can splurge on computers. The first weekend I had the machine, I had three kernal panics.
Among the other problems I have documented are the following: the dock hiding itself unbidden and other features checking and unchecking themselves (Aug 2002); bus errors connected with OS 9 (Sept); some problems that inspired the tech person (Eric)) to talk me through deleting my user i.d., resulting in the loss of two months worth of e-mail (Thursday, 12 September); Preview problems (September); a bizarre box with an unmovable and undeletable red stop sign in it that no tech person or other Mac user I know had ever hear of (Monday 30 September); printing problems; computer won't shut down, numerous disconnection errors, which turned out to be caused by an OS X update (beginning December, 2002, or later); Kernel panics (Feb); computer won't shut down (March); Faxstexx problems, program won't allow me to set it up, finally just deleted the software (April); keys like "V" freeze and repeat endlessly (May 21); DVD Player freezes (May); Safari and Mail begin quitting unexpectedly (May); cursor begins to blink and fade out, plus odd sounds come out of the speakers, a constant error beeping (Sept 9); DVD Player problems (Oct 4).
I called AppleCare while I had it about once a week (the total between August 2002 and the time it ran out was about 155 calls). Naturally, some of these calls are motivated by user error. On the other hand, many of the issues I have called about were unprecedented as far as the Tech person was concerned, such as the blinking mouse, the red stop sign, and the DVD Player woes.
Things improved with Panther, but in Tiger many of the same old issues have returned.
I have been having so many problems with my Mac that I once wrote a letter to the company asking when do I qualify for a new replacement machine. I never received an answer, but I felt better for about a day. Then I turned on my Mac again.

The spinning ball of death as we used to call it is often caused by a lack of RAM, it is hard to be sure as I am not working on your machine, but sometimes things can be improved with additional RAM, it makes it seem like a whole new computer.
A lot of your problems sound like stuff that can be fixed easily enough, and although frustrating things happen here and there with updates. It sounds like you are in fairly good spirits with it all, I would suggest just researching a bit more into maintenance you can do to help maintain the computer and educate yourself a bit more (sounds like you already have learned quite a bit along the way) and you will find a lot of these issues take you a few seconds to rid yourself of. I would start by making sure you are repairing permissions regularly and running the most up to date software. If a lot of problems persist, try creating a second user that is a "test" user to see if the problem is replicated on that user (don't delete your other one, but if you do find the problem not on the other user, you might have a corrupt user, however you don't have to lose all your emails there are plenty of ways to back it up and import it in, or even just bring the entire Mail folder from your library over to the new user). Another thing you can do if you find a lot of system problems is archive and install the OS, it takes a bit of time, but doing it overnight shouldn't be an issue, and you won't lose any of your stuff.

XPath expression failed to execute.

Hi Everybody ,
I am working AIA PIP 3.1 for JDE E1.I am facing some errors so that i can't proceed.
See the log errors as below:
javax.xml.ws.soap.SOAPFaultException: XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is ora:processXSLT('xsl/Xform_BillOfMaterialsListABM_to_BillOfMaterialsListAXML.xsl',bpws:getVariableData('InitialLoadBillOfMaterialsListReqMsg','InitialLoadBillOfMaterialsList'),bpws:getVariableData('Parameters')). The XPath expression failed to execute; the reason was: oracle.fabric.common.xml.xpath.XPathFunctionException: javax.xml.transform.TransformerException: oramds:/deployed-composites/default/InitialLoadBillOfMaterialsListJDEE1toAgileImpl_rev1.0/xsl/Xform_BillOfMaterialsListABM_to_BillOfMaterialsListAXML.xsl<Line 18, Column 271>: XML-22044: (Error) Extension function error: Error invoking 'lookupXRef':'oracle.tip.xref.exception.RepositoryException: lookup could not find values in column name "AGILE_01" for table name "oramds:/apps/AIAMetaData/xref/ITEM_ITEMID.xref" using reference column name "JDEE1_01" and reference value "731882::M30" Please ensure lookup criteria has a match.'. Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
Please reply me ASAP,
Waiting for your response.....

Hi,
Ya i checked the data for same table,but i didn't get any XREF related information in xref_data table.
Did you mean that, data should already present under AIAFPINST_XREF.Probably xref is meant for storing dynamic value.
Please check the above error and reply me soon.

Problem retrieving a list of values with XPATH

Hi,
I am trying to get a list of all 'Fields' (under the SubscriptionList -> EconomicIndicator -> Code) which have 'Provider' =DJ.
I am using the below xpath expression. But It is not working. I tried other variations but none of them return mulitple items.
Can some one please tell me if Iam missing something.
               XPathExpression xPathExpression= xpath.compile("/SubscriptionList/EconomicIndicator[*]/Code[Provider=DJ]/Fields");
               NodeList result = (NodeList)xPathExpression.evaluate(doc, XPathConstants.NODESET);
          for (int i = 0; i < result.getLength(); i++) {
               Element element = (Element)result.item(i);
          System.out.println(element.getNodeValue());

Hi DrClap,
I have a similar problem again. This time I am trying to extract a list of values from a xsd. Below is the code that I am using.
          try{
               djxsd = new FileInputStream("djei-3.1.xsd");
               XPathFactory factory = XPathFactory.newInstance();
               XPath xpath = factory.newXPath();
               SimpleNamespaceContext nsContext = new SimpleNamespaceContext();
               xpath.setNamespaceContext(nsContext);
               nsContext.addNamespace("xs", "http://www.w3.org/2001/XMLSchema");
               nsContext.addNamespace("xsi","http://www.w3.org/2001/XMLSchema-instance");
               +//String exp = "//xs:element/@name/text()";+
String exp = "/xs:schema/xs:group/xs:sequence/xs:element";
               XPathExpression xPathExpression= xpath.compile(exp);
               NodeList result = (NodeList)xPathExpression.evaluate(doc, XPathConstants.NODESET);
               FileOutputStream outputfile = new FileOutputStream("log.txt");
          for (int i = 0; i < result.getLength(); i++) {
               Element element = (Element)result.item(i);
               String output = element.getTextContent().trim();
               if(output.length() > 0)
                    outputfile.write(output.getBytes());
                    //System.out.println(output);
Highlighted in Itlalics is the actual expression that I want to use. For some reason this is not working .. it returns nothing.
The other expression works. Please let me know if there is anything wrong with the expression.

Appending Xpath Value to a variable in For Each loop

So I am iterating thru an XML File collection inside a ForEach container. I have an XML Task within this loop of type Xpath.
The Xpath expression on each file evaluates to a value which I want to append as I keep iterating.
How do I go about doing this?? I tried something like User::CheckSum =+ User::CheckSum but it gives and error and I am not sure on which property should it be applied to.
Please understand that it is not one file with multiple nodes but multiple XML files in my scenario.
Any help is much appreciated
SM

I do not think the variable's value gets preserved between hops, anyways, it does not look like a valid approach.
Use the XMLFile Source in the ForEach Loop and capture the needed value into a package variable that you can keep appending to say in a Script Task.

Syntax and format of a IF statement in formula XPath in a InfoPath field

Good day
I needed assistance with IF statement syntax in a InfoPath field formula.
If Field_1 = null
concat(substring-before(txtComponentNo1, "."), ".", substring-before(field17, "."), ".", substring-after(field17, "."))
Else
concat(substring-before(txtComponentNo1, "."), ".", substring-before(field17, "."), ".", substring-after(field17, ".")+1)
or in Advance XPath
If Field_1 = null
concat(substring-before(../../../my:grpComponent_1/my:grpComponent1/my:txtComponentNo1, "."), ".", substring-before(../../my:field17, "."), ".", substring-after(../../my:field17, "."))
Else
concat(substring-before(../../../my:grpComponent_1/my:grpComponent1/my:txtComponentNo1, "."), ".", substring-before(../../my:field17, "."), ".", substring-after(../../my:field17, ".") + 1)

Help with if statement in XPATH

Hi,
I´m using XPath to return a value for a conditional Branch in OSB, I understand that it is supposed to work with standard XPath so I post this question in this forum:
What I want to do should be simple but have not worked for me, I want to do an IF statement and to return one value in the then part or another value in else.
if the statement is acomplished I want tu return just a string and if it does not acomplish then in the else return a value from an Xpath expresion:
here something similar of what I´m trying:
if (./imp:iniciarCambio/cambios/bea:ListaDeCambios/bea:Cambio/bea:campoNombre/text() = "Name")
then M6yBilling
else ./imp:iniciarCambio/cambios/bea:companiaTipo/text()
The part that is not working is where I want to return M6yBilling if the statement acomplishes, I have tried "M6yBilling" also 'M6yBilling' and fn:string(M6yBilling) but none is working at all.
Any ideas?
Kind Regards,
Gerardo J

Xpath field details not getting displayed

Hi all,
I am working on a idoc to file scenario, where I want to refer the receiver to be determined based upon certain condition or values that get populated for a particular field (using receiver determination). But the problem is that when I click on the condition tab on receiver determination I get a warning "Problem loading schema description"
with message as
"Message interface does not exist in any software components installed on this business system"
But since it is an Idoc at the source we dont have any msg interfaces, further if i neglect this warning message and go further, I am not getting the fields or details of the Idoc structure getting displayed in the xpath.
But the same when I use for a file scenario(file as sender) I get the details of the context object if any.. Let me know how to resolve this..
Thanks in advance
Regards,
Nithiyanandam

Hi,
Yes you coudl add the missing Software component as per below steps
Even if you open Business system in Integration Directory, at last tab "Other Attributes" --> you will find the list of software components.
Press the tab Third Party service to verify the list against SLD.
If its not avaialbel in SLD
1. Goto System Landscape Directory
2. select Business Landscape and slect the apporpriate Business system and open it. (Click the name of BS)
3. There you will get the list of Software components added in it.
4. Verify the technical system name.
5. Also verify if same technical system name is used after importing the software component in Integration Repository (IR).
Goto IR -- > Explore the SCV -->Double click on name of software component version -->Check Interface Import as Import of RFC and have the same details in Connection data as per technical system
If everything is setup just refresh the SLD_CACH and import the scenario once again in Integration Directoy and process it.
You will see the IDOC in Business system.
Thanks

How to Get xml Attribute value from a given xpath

i'm building an xml from 3 columns a,b,c using 'SELECT EXTRACT (XMLELEMENT ("ROOT",.........)'
and my xml looks something like this
<ROOT>
<categories>
<catogory value="col a value" display="true"/>
<catogory value="col b value" display="false"/>
<catogory value="col c value" display="false"/>
</categories>
<DATAS>
</DATA>
</ROOT>
now under the datas node i want to use xpath like this
(case when '/root/categories/catogory/[@display="true"]' then '/root/categories/catogory/@value' else 0 end)
so tat i get values under data node based on display attributes.... is it possible..
if not is ther any alternative way of using xpath

What version of Oracle (4 digits)?
Are you trying to populate the Data node when you are building the XML originally via your SQL/XML statement or are you talking about modifying some existing XML to add more nodes to it based on data in the XML already?

Does SOA BPEL 11.1.7.0 support XPath 2.0 in XSLT mapping?

Dear Oracle support,
I am using SOA Suite 11.1.1.7.0 (local development) and 11.1.1.6.0 (in production, but will upgrade to 7). I came to the requirements need to do very complicated mapping using XSLT in BPEL. I would like to use some features of XPath 2.0.
Does SOA 11.1.1.6.0 or 11.1.1.7.0 have supported XPath 2.0? If not yet, is there any plan to support in the future?
Thank you in advance for your response,
Alena Li

Hi Alena Li,
Firstly, this is not Oracle support, this is Oracle forums...
https://wikis.oracle.com/display/Forums/Forums+FAQ
SOA supports *some* features of XPath 2.0 in XSLT, the infrastructure also supports XSLT 2.0, but JDEV mapper does not...
Check docs here...

Is there any possibility to combine XPath with SAX in Java?

HI Gentlemen,
I have an XML instance to parse. One solution works with XPath and Document builder. However, the tree in memory is too big so that I can not build it in my storage (8 GB). Does anyone of you know a method where I use an XPath expression (Java) to select a node but with a better parser (e g SAX) which is not so space hungry? Direct access of nodes is obligatory.
Thanks, kind regards from
Miklos HERBOLY

As SAX parsers do not build a DOM structure and XPath requires a DOM structure to select elements from, XPath is not usable with SAX, but some analysers support setting the XPath expressions to analyse before invoking the SAX parser and provide the result for XPath expressions.

Follow up on XPATH HashMap problem

Hi,
I got some great help before on this & am hoping for a little direction. I have a class that calculates the tax from an xml like below:
<Taxes>
     <Tax TaxCode='code1' Amount='101.00'/>
     <Tax TaxCode='code2' Amount='102.00'/>
     <Tax TaxCode='code3' Amount='103.00'/>
     <Tax TaxCode='code4' Amount='104.00'/>
     <Tax TaxCode='code5' Amount='105.00'/>
</Taxes>Now, my method below, gets the last 3 values and sums them and applies the code "XT" to it & returns a HashMap that looks like:
{code1 = 101.00, code = 102. 00, XT = 312.00}.
public static HashMap getTaxAmounts(String xml) throws Exception {
          HashMap taxes = new HashMap();
          DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
        domFactory.setNamespaceAware(true); // never forget this!
        DocumentBuilder builder = domFactory.newDocumentBuilder();
        Document doc = builder.parse(xml);
        XPathFactory factory = XPathFactory.newInstance();
        XPath xpath = factory.newXPath();
        XPathExpression expr = xpath.compile("//Tax/@TaxCode");
        Object result = expr.evaluate(doc, XPathConstants.NODESET);
        NodeList nodes = (NodeList) result;
        XPathExpression expr1 = xpath.compile("//Tax/@Amount");
        Object result1 = expr1.evaluate(doc, XPathConstants.NODESET);
        NodeList nodes1 = (NodeList) result1;
        for ( int i = 0; i < nodes1.getLength() && (i<2); i++) {
               taxes.put( nodes.item(i).getNodeValue(), nodes1.item(i).getNodeValue());
                if( nodes1.getLength() >= 3){
                    float total = 0.00f;
                    for ( int i = 2; i < nodes1.getLength(); i++) {
                            total += Float.parseFloat(nodes1.item(i).getNodeValue());
                    String xt = nodes.item(2).getNodeValue();
                    xt = "XT";
                    taxes.put( xt, total);
       return taxes;
/code]
all that's fine - but now I have to replace the tags in the original XML file so that they look like:<Taxes>
<Tax TaxCode='code1' Amount='101.00'/>
<Tax TaxCode='code2' Amount='102.00'/>
<Tax TaxCode='XT' Amount='312.00'/>
</Taxes>
any odeas how I would this???

Hi, John. I can address one of your questions here.
However, the picture was slightly cropped at the top and it also had 2 very small borders on the left and right, being printed in landscape.
A standard digital camera image is proportioned 4:3 (1.33:1). That doesn't match the 6:4 ratio of your paper's dimensions (1.5:1), so unless you opt either to distort the image or crop it, it can't be an exact fit on the paper.
In the toolbar at the top of iPhoto's Edit view is a pull-down menu above the word "Constrain". You use that menu to specify standard proportions for printing the image. Select "4x6 (Postcard)", and you will see superimposed on the picture a rectangle that has those proportions. What's inside the rectangle looks normal, signifying that it will be printed; what's outside the rectangle is pale and muted, because it will be cropped away when you print. Place your cursor anywhere inside the rectangle, hold the mouse button down and drag, to move the rectangle and change what's included within the print boundary.
The fact that your printed picture was both cropped and slightly reduced in size (creating the small left and right borders) suggests to me that your printer may not be capable of borderless printing, or that there is a setting for borderless prints you're overlooking somewhere. Since the contents of both the Print and Page Setup dialog boxes are governed by the printer's own driver software, and there's no "borderless" setting anywhere within iPhoto, I think you'll need to review the printer's documentation and/or online help files carefully to see whether you're overlooking something in one of those dialog boxes.

Is it possible to throw a BPELFault from a custom xpath function?

I'm probably revealing my lack of java chops here, but I'd like to know if there's a way to throw a BPELFault from the "call" method within a custom xpath function.
The interface for IXPathFunction seems to dictate that "call" throws only an XPathFunctionException and the bpel server doesn't handle this exception properly. It records the exception in the logs but then the process just dies.
Right now I have this (simplified code):
public Object call(IXPathContext context,
List args) throws XPathFunctionException
if (args.size() == 1)
// do some stuff and return a value
throw new XPathFunctionException( "hexToInt() requires one string argument." );
What I want to have is something like this:
public Object call(IXPathContext context,
List args) throws BPELFault
if (args.size() == 1)
// do some stuff and return a value
BPELFault fault = new BPELFault(
new javax.xml.namespace.QName("http://schemas.xmlsoap.org/ws/2003/03/business-process/",
"selectionFailure"));
fault.setPart("code", "intToHex");
fault.setPart("summary", "hexToInt() requires one string argument.");
throw fault;
If I do this, the compiler rejects it saying that "call" must throw XPathFunctionException. Is there a way to extend the IXPathFunction interface to allow it to throw a useful fault?
Thanks!
Sean

Yeah, I'm using that patch (otherwise the process just crashes and you don't have a chance to catch the fault, even in a catchAll). Within the catchAll you can get the details from the error with something like this:
<copy>
<from expression="concat(ora:getFaultName(),'')"/>
<to variable="processFault" part="payload" query="/ns4:summary"/>
</copy>
<copy>
<from expression="concat(ora:getFaultAsString(),'')"/>
<to variable="processFault" part="payload" query="/ns4:detail"/>
</copy>

ICal woes - any help please

Hi everyone, I am having some major iCal woes that I hope someone has the answer to.
Ok this is how I handle my workflow. I have numerous calendars such as "call", "viewing", "meeting", "work misc", "personal" etc. All colour coded and I use the month view as standard.
Under SL I would double click the day I add an event go through the boxes (name, location, time, etc) click save and job done.
Now under Lion when I double click a day I get an event box but only the header. So I have to type the header hit return then double click on the event again to get the box up so I can assign the event the right time and calendar to use. This is taking twice as long as it did before under SL and is a pain when you have a client on the phone. Am I missing something here? Why is it now so hard? - and I have tried that quick entry business but it doesn't work for me, I simply want the whole calendar entry box when I double click in month view.
Next problem is all new events go in as a all day event. Again another click I didn't need to do in SL. Then untick all day and enter a time LionCal doesn't set the end time 1 hour later anymore it sets it hours later for me, sometimes into the next day so I have to click into the date box and type the end date, again a massive slow down in my workflow.
Finally and most annoyingly in month view I cannot for the life of me get a 12 hour clock with AM/PM. I checked my international page in sys prefs and all is ok but LionCal is not playing ball.
Any help would be appreciated as I love iCal and run my life with it over MobileMe.

If you want to Commit changes at every record level in a Multi-Record Block, you may have to write the following triggers at the block level :-
1) Key-Down
2) Key-Up
3) You will also have to handle Mouse Events
i.e When-Mosue-Click etc
In each of these triggers, issue a commit statement :-
i.e.
Trigger Name :- KEY-DOWN [ Defined at Block Level ]
Trigger Code
Commit_Form;
Next_Record;
The Commit_Form statement will display a message for the user to COMMIT transaction to the DB.
