Using namespaces in the XML QUERY

I need to included a namespace of i: in the query below.
the namespace is : "http://abc.com/int:i"
How can I include the namespace in the query below?
Is this possible?
SELECT XMLELEMENT("i:Trade", XMLELEMENT("i:Level",2.25),
                             XMLELEMENT("i:Style", 250),
                             XMLELEMENT("i:Size"),
                             XMLELEMENT("i:Block.Number"))
                FROM DUAL

How to retrieve multiple columns using "returning" in the Insert query.

hi,
wanted to know how to retrieve multiple columns using "returning" in the Insert Query.
For retrieving one column we write the query as follows:
Insert into TABLE values(1,2,3,4) returning COLUMN1 into PARAMETER
But can we retrive multiple columns in the same query?
am using oracle 10g and coding in .NET

Hi,
You can definetely get multiple values from a single query using the 'returning' clause.
Eg : insert into emp (empno, ename, job, deptno) values (7324,'ADAM','MARKETING',30) returning ename, deptno into var1, var2; PN : var1 & var2 to be declared as varchar2 & number respectively.
More insight into the 'RETURNING' clause in this link.

How to use XPath with Namespaces in the xml ?

Hi all,
I need to reference a certain Node in a Document using XPath notation.
The problem is the the XML Document contains Namespaces inside it
f.e.
<xn:SubNetwork id="JRANM">
    <xn:VsDataContainer id="1">
       <xn:vsDataType>vsDataAreas</xn:vsDataType>
    </xn:VsDataContainer>
</xn:SubNetwork >Using DOMXPath (from weblogic.xml.xpath)
DOMXPath xPath = new DOMXPath("xn:SubNetwork/*");
Set nodeset = xPath.evaluateAsNodeset(this.xmlRootElement);When I Iterate through the Set I can see it's empty.
(On the other hand without namespaces everything is fine.)
So how can I reference a Node that contains a namespace in it ?
Thanks a lot

How-to use Excel for the XML file input?

Hello all,
Following our discussion with Gerhard Steinhuber on the very nice tutorial from Horst Schaude , "How to upload mass data via XML File Input" , I am starting this new discussion.
In the comments section of this previous cited tutorial, Rufat Gadirov explains how to use a generated XML from Eclipse instead of your XSD file as your source in Excel.
However, in spite of all the instructions, I am still facing the same issue in Excel when I try to save my file as XML : "The XML maps in this workbook are not exportable".
What I try to do is to create one or more Sales Orders with multiple Items in it from a XML File Input, using excel to enter data.
The part with the File input is working (if I directly upload my file to the webDAV, it creates a sales order instance with multiple items).
The only missing part is the Excel data input that I cannot make work. Any help on this matter would be greatly appreciated.
Here is my XML file that I try to use as a source in Excel before inputing data from Excel:

Hello Jacques-Antoine,
I suppose that as you have tried to construct a map from the schema, you have taken the elements from the List level down. In this case I also can't export the map.
But if you take the elements from the level MySalesOrderUploaded down, you'll get the exportable map (screenshots)

What application should i use to create the xml data as the input data for XFA template

HI,
I need to generate pdf or html document form from existing XDP with the given xml formatted data set. We usually use word to generate content for those XFA template, as the data should be in xml format content in word document should be able to convert into xml document that is compatible with XFA template. I want to know if there is any tool to conver word doument content to xml format that is compatible with XFA template or has adobe given their own tool to create content that comply with XFA template? . Also i want to know if i can do above mention functionality jaut with adobe forms if not what are the other services that i should use. Please give me the prices of adobe forms and any other tool that i should use. Thank you

XFA is just the definition of the form template. Once you have an XFA based template, you can merge any XML you want.
The trick is do the appropriate binding so the data from the XML goes in the right fields on your form. This binding is done using LiveCycle Designer.

Using informations about the XML Data Set in *.js

Dear Users,
I hope I am able to explane my problem correctly:
I wonna create a fade effect with various pictures. They don't should blend to 0 - I found a js script that lets the pictures fade from one to the other like this: www.sv-guenther.de
What this script needs is the number of pictures. I put the picture links into an XML file. Everything works as long as write the number or length of the picture children manually.
I tried to read out the length by using the ds_RowCount option. This works fine as long as I use this in HTML context like this:
<div spry:region="ds1" ><script type="text/javascript"> alert({ds_RowCount});</script>{ds_RowCount}</div>
Both works: The alert shows the number 21 AND you can read the "21" and not {ds_RowCount}.
okay, but how do I use the "21" integer in a script block in the head area? like this:
<head>
<script type="text/javascript">
var x = {ds_RowCount};
</script>
</head>
I tried it in different ways: var x = '{ds_RowCount}'; or spry:....
As you can see: I am afraid my scripting knowledge is not the best - like my English is...
Sorry and thank you very much for your help! - any kind of help

Dear Ben,
if you would see me, you wouldn't laugh anymore, you would cry -) - but you are in DownUnder - this would look like I am laughing for you - wouldn't it?
Thank yoou so much for remembering me. I have been reading your post about this topic (blend a picture). Once somebody asked the same (or almost the same) like I did yesterday. But the difference is, that if you blend a text to 0 it is big diference blending a picture - in my mind. I would love to reduce the opacity from one picture when the next picture is already behind it. So it looks like a smooth fade in fade out, without displaying the background.
I found a quite good code example for this:HERE
To make it as easy as possible for me I tried to include the number of the pictures straight into the js code. in the meantime I found the correct code option for this: What I was looking for was: getData() and if I combine it with an observer to wait for the "onPostLoad" everything works fine. I am ashamed that I asked first and then lokked into the SPRY API - Sorry!
Everything works fine? No not yet - unfourtunally. So I am pleased to get the chance to ask a second time:
Let's say I have more than one picture and more than one topic. So my XML looks like this:

First I create an new object
var ds1 = new Spry.Data.XMLDataSet("xml/leistungen.xml", "leistungen/inhalte/inhalt/texte");
So the dsR = ds1.getData() gives me a dsR.length = 8 - correct - because this XML has got 8 <texte> nodes. But some of these <texte> nodes have more than one <text> node. If I asked for the contet of the fifth node dsR[4]["text"] it gives me back "Bürogebäude" = the last sub node content. I wished I could catch the first, second, third as well. Just like a spry:repeat - do you understand?
I figured out that it doesn't help to extend the string like
dsR[4][0]["text"] or dsR[4][0][0].
As far as I understood the Spry framework flattens the XML like a table. So I thought that there might be just in this raw, in the actual column just another object (not a string) to be found.This object I could touch or open with square brackets. Like
dsR[0]["texte"][0]
- but: I can't!
But this would mean, that straight in js I could always only catch the first node value??? I must be wrong!!! But I don't know were!
Dear Ben, Dear Guys out there - is this to difficult what I am looking for or am I blind?

<i:StopPx>480.25</i:StopPx>
<i:Issr>Barclays</i:Issr>

</i:Interest>i know that this is not the forum to ask XSLT,but as I am using 10G with SQL,can anyone
just send in a small XSLT script which I can use as a template and create XSLT.
This is the first time I am using XSLT.
Again,no offence meant if this is not the correct forum but help really appreciated.

Using XPath with the XML DOM

I have just started to use the XML DOM API. One thing I cannot see yet is an easy way to use XPath to get the value of an element.
What I would like to do is pass an XPath expression like this:
\EDIFACT\ORDERS\NAD[2]\NAD01\NAD0102
into a method, and get the value of the element returned to me.
Does anybody know if there is a method of one of the DOM interfaces that would provide that kind of functionality, or am I going to have to traverse the nodes of the DOM tree manually to do this?
BR,
Tony.

Hi Tony,
I read your posted question - I have the same problem.
I think that the method find_from_path_ns (or find_from_path) is the only "xpath"-like way to get a value.
BUT the syntax is very limited so you cannot use all good features of xpath
To traverse the nodes manually is (in my problem) unpractible - the xml-structures are different and it's horrible to traverse the tree.
I need xpaths like ' //x/y[3]/z[a='MS']' . I know, the performance is not very good but for small XML-messages fast enough
Do you have any solutions?

Use of Global Properties in URL path of XML Query

I am trying to use global properties to define the URL of XML query:
Globals.ImageFilePath&"SomePath/\File.xml"
but it does not like it. If I put the content of the Globals.ImageFilePath it works fine. What is the synatax for that?
I am using the XML query in a transaction within an image creation action block. When I try to define the URL parameter of the XML file as a link, it is not taken on account, and the image created has no data (it is empty). The URL is taken when defined on the Cofigure Object screen, but there I have the same problem to use the global variable parameter.
Any suggestions?
Thanks,
Vlad

As I mentioned in my first posting, yes, I can put the global variable of the link editor for the URL parameter, it evaluates well, but it is not taken on account by the query, and the image generated is empty. Obviously there is a bug here, so I am trying to find a work around to use the global variable on the Configure Object screen, where the parameter URL is taken by the XML query, but on this screen I can not use the global variable. It works only if I put the content of the global variable.
So, does anybody know if we can use global variables on a Configure Object screen, or on the XML query URL field, and if so, what is the syntax to indicate global variable?
Thanks again,

Using API to download the webi document in the XML format

I am just trying to use this API to download the webi document in the XML format. I need a sample XSL file which we can use to download the XML in a formatted output.
http://devlibrary.businessobjects.com/BusinessObjectsXIR2/en/en/RE_SDK/resdk_java_doc/doc/resdk_java_apiRef/com/businessobjects/rebean/wi/XMLView.html
getReader
public java.io.Reader getReader(java.net.URL xsl)
throws REException
Return the result of the XSL transformation applied to the XML report output stream.
Parameters:
xsl - URL to an XSL file used to transform report XML.
Since:
11.5
See Also:
getReader()

If the same content of file already thr in the Internal table as 1 STRING/LINE then you can loop the internal table count the entries which one you want like

Cooresponding Lists Names/Values XML Query

Let's say there is an XML Schema that has
<element name="mt" minOccurs="0" maxOccurs="unbounded">
<element name="r" minOccurs="0" maxOccurs="unbounded">
And for each measurement type (mt), you have a cooresponding measurement value (r). There are additional elements between these two lists. The actual XML data would look similiar to
<mi>
     <mts>20061117100000-0800</mts>
     <gp>900</gp>
     <mt>MeasurementType1</mt>
     <mt>MeasurementType2</mt>
     <mt>MeasurementType3</mt>
     <mt>MeasurementType4</mt>
     <mt>MeasurementType5</mt>
     <mt>MeasurementType6</mt>
     <mt>MeasurementType7</mt>
     <mv>
          <moid>Identifier</moid>
          <r>58</r>
          <r>62</r>
          <r>43</r>
          <r>45</r>
          <r>43</r>
          <r>14</r>
          <r>29</r>
          <sf>FALSE</sf>
     </mv>
</mi>
The first occurance of mt corresponds to the first occurance of r, the second cooresponds to the second, et cetra.
The MI element can repeat hundreds of times and there can be many measurementTypes. Now, I'm trying to figure out how I can create an XML query to efficiently handle this. The problem is that the <r> value is within the complexType <mv> and that is on the same level as <mt>. The XML Query would cause a cartesian product if I were to use something like ...
select
extractValue(value(xmldata), '/mi/mts') measurement_time_stamp,
extractValue(value(xmldata), '/mi/gp') granularity_period,
extractValue(value(mt), '/mt') measurement_type,
extractValue(value(mv), '/mv/moid') measured_obj_id,
extractValue(value(r), '/r') measurement_value,
from xmltable
, TABLE(XMLSequence(Extract(value(xmltable), '/mi/mv'))) mv
, TABLE(XMLSequence(Extract(value(mi), '/mi/mt'))) mt
, TABLE(XMLSequence(Extract(value(mi), '/mv/r'))) r
This obviously wouldn't work. I could go and store all the types and values into a column using
select
replace(replace(replace(extract(value(mi), '/mi/mt').getStringVal(), '</mt><mt>', ';'), '<mt>'), '</mt>') measurement_type,
extractValue(value(mv), '/mv/moid') measured_obj_id,
replace(replace(replace(extract(value(mv), '/mv/r').getStringVal(), '</r><r>', ';'), '<r>'), '</r>') measurement_value
from xmltable
TABLE(XMLSequence(Extract(value(xmldata), '/md/mi'))) mi
, TABLE(XMLSequence(Extract(value(mi), '/mi/mv'))) mv
But this wouldn't work once the XML grew over 4000 bytes. So I need a way to extract this data maintaining the correct integrity (avoiding cartesians).
One idea is a pipelined table function but I have concerns about scalability with that method. Is there a way to accomplish this optimally? I have solutions for this but none of them is going to deliver the scalability I am seeking.
I expect the method chosen will probably need to handle a few hundred thousand files per day.
Thanks,

I'd not seen your XML schema when I worked the original example, so I reverse engineered it from the instance. Unfortunately when I work with your schema, which contains more levels of nested I can't get it to optimize properly
Here's what should work in theory

SQL>As you can see the re-write is not working out in this case. I'll ask development to take a look at it and see if they can solve it. I think it's similar to another bug I've filed...
WRT to your question about transforming. One easy transformation would be to number the nodes.. Eg use XSTL to add an index number to each MT node and each R node and then join on that value.
