Navigating elements using XPath through SDK

Hi there,
Here is my code:
InterfacePtr<IXMLParserUtils> xmlparse(doc, IID_IXMLPARSERUTILS);
xmlparse->EvaluateXPathsForElement();
(I yet to derive parameters.) However my error is:
error C2039: 'EvaluateXPathsForElement' : is not a member of 'IXMLParserUtils'
I look at the IXMLParserUtils header file. "EvaluateXPathsForElement" is the member of "IXMLParserUtils".
I dont know why this strange error.
Thank in advance.

You're missing includes and using undeclared variables (e.g. application).
For the actual arguments, use the typedef rather than copying their basic definition.
Copy the method prototype from the IXMLParserUtils.h.
Paste twice.
virtual bool16 EvaluateXPathsForElement(const K2Vector<WideString>& xPaths, InterfacePtr<IIDXMLElement> rootElement, HitMatches& matches, PrefixToURIMap* prefixMap) const = 0;
virtual bool16 EvaluateXPathsForElement(const K2Vector<WideString>& xPaths, InterfacePtr<IIDXMLElement> rootElement, HitMatches& matches, PrefixToURIMap* prefixMap) const = 0;
The first pasting gives a bunch of variables, the second uses them. This is C++ not Java, so most of the time some operators have to go when you turn references to actual storing variables. In the opposite direction, you have to use the address-of operators "&" to pass a variable into a pointer "*" argument.
bool16 result;
K2Vector<WideString> xPaths;
InterfacePtr<IIDXMLElement> rootElement;
HitMatches matches;
PrefixToURIMap prefixMap;
result = EvaluateXPathsForElement(xPaths,rootElement,matches,&prefixMap);
My changes to your original code:
K2Vector<WideString> choices;
InterfacePtr<IIDXMLElement> root_elt ( xmlutils->QueryRootElement(doc) );
HitMatches hitMatches;
PrefixToURIMap prefixToURIMap;
xmlparse->EvaluateXPathsForElement(choices, root_elt, hitMatches,&prefixToURIMap);
This compiles for me. I did not waste any thoughts on how far your arguments actually make sense beyond that.
It frequently helps to swap compilers when you encounter such problems. Just recompile in OSX XCode and CodeWarrior if you can't make a sense from VC messages, and vice versa.

Xslt copy-of creates a xml which returns empty while trying to access elements using XPATH

Hi
I am trying to do a copy-of function using the XSLT in jdev. This is what I do
    <xsl:param name="appdataDO"/>
    <xsl:template match="/">
    <ns1:applicationData>
      <ns1:applicationId>
        <xsl:value-of select="$appdataDO/ns1:applicationData/ns1:applicationId"/>
      </ns1:applicationId>
      <xsl:copy-of select="/fslo:ExternalapplicationData/fslo:ApplicationsHDRAddInfo">
      </xsl:copy-of>
    </ns1:applicationData>
    </xsl:template>
    </xsl:stylesheet>
After this I can see the document created in the process flow as this :
    <ns1:applicationData>
    <ns1:applicationId>MMMM</ns1:applicationId>
    <ns2:ApplicationsHDRAddInfo>
    <ns3:genericFromBasePrimitive>iuoui</ns3:genericFromBasePrimitive>
    <ns4:EstimatedMarketValue>77</ns4:EstimatedMarketValue>
    <ns4:PropertyInsuranceFee>jih</ns4:PropertyInsuranceFee>
    <ns4:LoanOriginationFee>hjh</ns4:LoanOriginationFee>
    <ns4:RegistrarFee>kkkkk</ns4:RegistrarFee>
    <ns4:LoanCashInFee>hjh</ns4:LoanCashInFee>
    <ns4:LoanPaidInCashFlag>cddffgd</ns4:LoanPaidInCashFlag>
    </ns2:ApplicationsHDRAddInfo>
    </ns1:applicationData>
But whenever I am trying to extract any of the output nodes I am getting an empty result. I can copy the whole dataset into similar kind of variable.
But I am unable to get individual elements using XPATH.
I tried using exslt function for node set and xslt 2.0 without avail.
The namespaces might be the culprit here . The test method in the jdev is able to output a result but at runtime the xpath returns empty .
I have created another transform where I try to copy data from the precious dataobject to a simple string in another data object .
This is the test sample source xml for the transform created by jdev while testing with all namespaces, where I try to copy the data in a simple string in another data object.
    <applicationData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.oracle.com/bpmpa/fs/ulo/types file:/C:/JDeveloper/NewAPP/Xfrm/xsd/ApplicationData.xsd" xmlns="http://xmlns.oracle.com/bpmpa/fs/ulo/types">

       </ApplicationsHDRAddInfo>
    </applicationData>
And the xslt
    <xsl:template match="/">
        <ns1:DefaultOutput>
          <ns1:attribute1>
            <xsl:value-of select="/fslo:applicationData/fslo:ApplicationsHDRAddInfo/custom:LoanOriginationFee"/>
          </ns1:attribute1>
        </ns1:DefaultOutput>
      </xsl:template>
This results in a empty attribute1. Any help will be appreciated .

OWSM - Signing element using XPATH Expression

Hi,
We have a requirement to sign an element within outgoing body of xml message. We are trying to use the policy pipeline to sign.
Signed Content: XPATH
sign XPATH Expression: referencing the element required to be signed.
We get the error: WS-Security process failure:There are no parts of the message to sign
The error message indicates that the XPATH query is not correct. Does anyone know of a source of documentation for this where we can get examples. Tried google, forums...etc with no success. Any help would be really appreciated.
Thanks

Using 'Launch Application' through SDK

Hi,
I want to know if there exists a way of using the 'Launch Application' feature through SDK other than using something like System.Diagnostics.Process.Start("***.exe").
Thanks,
Binita

Hi Binita,
You can use the following code:
oApplication.ActivateMenuItem("523")
oForm = oApplication.Forms.ActiveForm
If oForm.TypeEx = "20100" Then
oForm.Items.Item("3").Specific.Columns.Item("0").Cells.Item(1).Click() '// replace 1 with whatever row you want
oForm.Items.Item("1").Click()
End If

How to use Xpath to query elements loaded from different xml docs?

I have a big DBLP XML doc (95mb), to load into the container, i splitted the doc into many small xml docs by the publication types, such as articles, books, inproceedings, etc.
I tried to use xpath query such as
query 'collection()/dblp[article/author]/book[title]'
I got empty answers.
but if i use XQuery such as
query 'let $r:=collection()/dblp,$a :=$r/inproceedings/author
for $l2 in $r/book
where $a and $l2/title
return <result> {$l2}{$a}</result>'
i got answers. However, if i remove {$a} from the return clause, i still got empty answers.
is there any problem with my Xpath query and flwor Xquery?

Hi John,
Following is the procedure i have used to load the xml docs (after the indexes have been created):
private static void loadXmlFiles(File path2DbEnv,String theContainer, File file) throws Throwable {
     //Open a container in the db environment
          XmlManager theMgr = null;
          XmlContainer openedContainer = null;
          myDbEnv env;
          try {
          env = new myDbEnv(path2DbEnv);
     theMgr = new XmlManager(env.getEnvironment(), new XmlManagerConfig());
     //use node container
     theMgr.setDefaultContainerType(XmlContainer.NodeContainer);
               try{
               openedContainer = theMgr.createContainer(theContainer);
               }catch (XmlException e){
                    //if the container alreay exist, then open it;
                    openedContainer = theMgr.openContainer(theContainer);
          //Get an update context.
          XmlUpdateContext updateContext = theMgr.createUpdateContext();
               String theFile = file.toString();
               String docName=file.getName();
          //Get the input stream.
          XmlInputStream theStream = theMgr.createLocalFileInputStream(theFile);
          System.out.println("Adding " + theFile + " to container " +
                         theContainer);
     //     Do the actual put
          openedContainer.putDocument(docName, // The document's name
          theStream, // The actual document.
          updateContext, // The update context
     //     (required).
          null); // XmlDocumentConfig object
          System.out.println("done.");
          //XmlException extends DatabaseException, which in turn extends Exception.
          // Catching Exception catches them all.
          } catch (XmlException e){
               System.err.println("Error loading files into container " + theContainer);
               System.err.println(" Message: " + e.getMessage());
               //In the event of an error, we abort the operation
               // The database is left in the same state as it was in before
               // we started this operation.
               throw e;
          finally {
          cleanup(theMgr, openedContainer);
Unfortunately, i waited for around 20 hours 148mb doc was not loaded; so i gave up.
Could you please give me some suggestions on how to load the large doc efficiently ? thanks.

Copying Variables in BPEL using XPath Query

Hi,
I am new to BPEL and i want to know if it is possible to copy data from one variable to another using XPath Query in the <from> <to> tags, when the two variables are of different message types.
I am trying to create a sample BPEL that would receive a String through the receive tag tied to one partner link (WSDl) and then invoke a different webservice using the <invoke> tag tied to another partner link (WSDL) by passing the received variable.
I have pasted the BPEL File and the two WSDl files involved.
My Issue is that when I send a soap request to the BPEL, it is passed as null to the webservice invoked.
Probably because the copy tags don't work.
Please help.

Hi,
Yes, it very much is possible.
Xpath query provides a lot many data type conversion functions(string to int, string to date etc), which can be used in copying variables.
thanks

SSMS 2012:FOR XML PATH Using XPath Node Tests-Columnn name 'test()' contains an invalid XML identifier as required by FOR XML?

Hi all,
I am learning XPATH and XQUERY from the Book "Pro T-SQL 2008 Programmer's Guide" written by Michael Coles, (published by apress). I copied the Code Listing 12-8 FOR XML PATH Using XPath Node Tests (listed below) and executed it in my

I feel this xml output is not like the regular xml output. Do you know why it is diffrent from the regular xml xml output? Please comment on this matter.
Thanks,
Scott Chang
What do you mean by regular xml document? Are you referring to fact that its missing a root element? if yes it can be added as below
USE AdventureWorks;
GO
SELECT
p.NameStyle AS "processing-instruction(nameStyle)",
p.BusinessEntityID AS "Person/@ID",
p.ModifiedDate AS "comment()",
pp.PhoneNumber AS "text()",
FirstName AS "Person/Name/First",
MiddleName AS "Person/Name/Middle",
LastName AS "Person/Name/Last",
EmailAddress AS "Person/Email"
FROM Person.Person p
INNER JOIN Person.EmailAddress e
ON p.BusinessEntityID = e.BusinessEntityID
INNER JOIN Person.PersonPhone pp
ON p.BusinessEntityID = pp.BusinessEntityID
FOR XML PATH('ElementName'),ROOT('RootName');
replace ElementName and RootName with whatever name you need to set for element as well as the root element

Using XPath for DOM traversal

This question falls into the category of 'I know it's possible, I just need to find the idom in Java'.
I'm coming from a MSFT world were the DOM-centric model of XML processing makes heavy use of XPATH for node selection. Basically using the method element.selectNodes(XPathExpresson) allows one to quickly extract the relevant subset of the parsed tree in the DOM as a nodeList. I've become accustomed to using XML for all strucutured storage that doesn't require a full database.
The W3C DOM Level 3 spec supports evaluateExpression() for this purpose, but I can't believe that Java developers are still using tree traversal waiting for the spec to be implemented. I suppose that I could use getNodesByTagName(), but this is a chainsaw, and I need a scalpel. Anyway, I'm trying to figure out how, exactly, this gets done in Java.
I figure the following are possibilities:
1) It's in JAXP and I missed it
2) One or more of the XML parsers supports XPATH as an extention
3) There's a common package that sits on top of the DOM Document.
4) There's a standard way to apply and XSLT methods to the DOM document
5) Something I've never thought of.
This is a generalized problem for me, so I can't rely on object serialization, Java-XML data mapping, etc. Any guidance would be greatly appreciated.

I've written a Config file reader for XML in java,
and it extracts values using XPath. This is
some of the code you'll need:
imports:
import javax.xml.transform.TransformerException;
import org.w3c.dom.*;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.apache.xerces.parsers.DOMParser;
import org.apache.xpath.XPathAPI;
import org.apache.xpath.objects.*;
Document doc=....;
* returns a single DOM Node from the config file.
public Node getNode(String xpath) throws ConfigException {
try {

Using XPath to create nodes

Hi,
Obviously the main use of XPath is to query the state of an XML document... the equivalent to a "select" statement in SQL.
DOM4J has methods that allow you to use XPath as the equivalent to "insert" statements in SQL. You can specify an XPath like "/Hello/World/Value = 3" and apply this XPath to an XML document so that it creates something like this for you:
<Hello>
<World>
<Value>3</Value>
</World>
</Hello>
This is actually very useful for an investment banking application that I'm working on.
The problem with DOM4J is that it doesn't handle attributes or conditionals well. If you specify
/Hello[@name=2]/World = 3
I would expect
<Hello name=2>
<World>3</World>
</Hello>
to be produced. Instead, it produces
<Hello[@name=2]>
<World>3</World>
</Hello>
These are all simple examples. What I'm doing in real life is using XPath to insert nodes into a complicated XML document that already has a lot of structure. I'm only adding one or two elements to big documents.
Is there anything at all like this available in the JDK 1.5 release. I've had a good look, and XPath looks like it's only for queries. Is this correct?

I think this might do what you need...
// Create a dummy XML document
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
InputStream bais = new ByteArrayInputStream("<test><e1/></test>".getBytes());
Document doc = db.parse(bais);
// Define the XPath expression to "select" the parent element in the document
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression xpathExpression = xpath.compile("/test/e1");
// Select the parent node (should probably chuck an ex if not present)
Node node = (Node) xpathExpression.evaluate(doc, XPathConstants.NODE);
// Create and append the child element
node.appendChild(doc.createElement("newElement"));
// Convert the Document into a string
ByteArrayOutputStream baos = new ByteArrayOutputStream();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(baos);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(source, result);
// <?xml version="1.0" encoding="UTF-8"?><test><e1><newElement/></e1></test>
System.out.println(baos.toString());

Using XPATH to extract value.

I need some help to extract the LatestFillQuantity element value using XPATH.
in Java.
I am unable to extract the value of 10000.
Please help as to what have I done wrong.?
The Document configNode contains the flwg:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<i:Interest >
     <i:Generation>3</i:Generation>
     <i:Extension>
        <i:Active.From/>
        <i:Order>
          <i:Status>Confirm</i:Status>
          <i:LatestFillQuantity>100</i:LatestFillQuantity>
        </i:Order>
</i:Extension>
</i:Interest>
My Java Code
private void extractValue(Document configNode)
     XPathFactory factory = XPathFactory.newInstance();
        XPath xpath = factory.newXPath();
          try{
         XPathExpression expr
          = xpath.compile("//i:Order/i:LatestFillQuantity/text()");
         Object result = expr.evaluate(configNode, XPathConstants.NODESET);
         NodeList nodes = (NodeList) result;
         for (int i = 0; i < nodes.getLength(); i++) {
             System.out.println(nodes.item(i).getNodeValue());
         }catch(Exception e){
              System.out.println("Sorry,this aint working");
     }

The nodes being parsed are namespace prefixed.
To parse a namespace node with the JDK 5.0 javax.xml.xpath package, set the NamespaceContext on the XPath object.
An implementation of NamespaceContext with a single prefix corresponding to a namespace uri:
public class NamespaceContextImpl implements NamespaceContext{
public String uri;
public String prefix;
public NamespaceContextImpl(){}
public NamespaceContextImpl(String prefix, String uri){
     this.uri=uri;
     this.prefix=prefix;
public String getNamespaceURI(String prefix){
   return uri;
public void setNamespaceURI(String uri){
   this.uri=uri;
public String getPrefix(String uri){
   return prefix;
public void setPrefix(String prefix){
   this.prefix=prefix;
public Iterator getPrefixes(String uri){return null;}
}

Accessing documents in xml db in browser using xpath not returning results

I have loaded the purchaseorder documents and schema (from Oracle Magazine article (Mar/Apr 2003) "From XML to Storage and Back" article.
I am able to access the LineItems element of the purchaseorder document using:
http://localhost:8080/oradb/SCOTT/PURCHASEORDER/ROW/PurchaseOrder[Reference="ADAMS-20011127121040988PST"]/LineItems
However, I cannot access the indivicual LineItem elements using the ItemNumber attribute:
http://localhost:8080/oradb/SCOTT/PURCHASEORDER/ROW/PurchaseOrder[Reference="ADAMS-20011127121040988PST"]/LineItems/LineItem[@ItemNumber="2"]
I get the following result:
<?xml version="1.0"?>
<ERROR>ORA-00904::invalid identifier</ERROR>
I need to be able to use this and other xpath statements to extract elements from my document. Any suggestions?

I'm including a sample purchase order:
<?xml version="1.0" ?>

Using TLF with SDK 3.5 - 1014 error

Hi
I have followed the steps outlined at http://opensource.adobe.com/wiki/display/tlf/Using+TLF+with+Flex+3.2 to import TLF to user with SDK 3.5. I have verified that I have the latest swc. I get no compile erros but at runtime I get
VerifyError: Error #1014: Class flashx.textLayout.elements::TextFlow could not be found
Any help would be greatly appreciated.

I have never use TLF with SDK 3.5.
After reading what you have said, I guess you are setting SWCs in your project as "runtime shared Library", but there is not a RSL link( or not a correct RSL link) in the configuration file named flex-config.xml in SDK 3.5, to download the SWF or SWZ successfully in the runtime. You may solve the problem by setting libraries as "merge into code"

How to call the javascript file through sdk?

I created a plugin through SDK. Now i need to call my javascript file in that plugin code(c++). Could you please advice me with some samples. This is for "Illustrator CS".
Thanks,
Prabudass

I haven't the foggiest idea, except to perhaps suggest firing a script by using the AIActionManager::PlayAction command. That's assuming you can 'action' the use of a script though. If you can, it should be possible that way, if not, I have no idea.
