SsIncludeXml does not return the expected output

Question

Hi
In the context of SiteStudio 10gR4:
I want to emulate a simple key-value-map using a static list. The purpose is enable authors to reference frequently-changed text-variables and maintain them in a single file.
When I attempt to use the ssIncludeXml function to place the value on a page, I get no result outputted. I have checked (using the XML-features in Oracle JDeveloper 11g) that the XPath actually evaluates to the expected value (FLAF_VAL_1). When I call the ssGetXmlNodeCount function with the same arguments, I get the result "0".
What am I doing wrong? Is there any limitations on the kinds of XPath expressions that ssIncludeXml will evaluate?
Thanks!
I use this snippet to include the value:
[!--$ ssIncludeXml("KEYVAL_TEST", "//wcm:element[@name='Key'][text()='FLAF_KEY_1']/../wcm:element[@name='Value']/node()") --]And this is my test file in the document KEYVAL_TEST:
<?xml version="1.0" encoding="UTF-8"?>
<wcm:root xmlns:wcm="http://www.stellent.com/wcm-data/ns/8.0.0" version="8.0.0.0">
<wcm:list name="KeyValuePairs">
    <wcm:row>
      <wcm:element name="Key">FLAF_KEY_1</wcm:element>
      <wcm:element name="Value">FLAF_VAL_1</wcm:element>
    </wcm:row>
    <wcm:row>
      <wcm:element name="Key">FLAF_KEY_2</wcm:element>
      <wcm:element name="Value">FLAF_VAL_2</wcm:element>
    </wcm:row>
  </wcm:list>
</wcm:root>

Thank you for your reply!! It is great getting some helpful input to help me move forward on this issue!
2. What you are doing in the example is a bit simpler and not really sufficient to express the query, I need to perform.
I need to select the contents of a Value-element based on the value in corresponding Key-element in the row.
This can easily be formulated using XPath. I have already posted a few different XPath expressions that are equvalent for this XML-file. Each of the expressions works perfectly in JDeveloper when querying the XML-file, and yet fails in Site Studio.
The [Technical Reference|http://download.oracle.com/docs/cd/E10316_01/ouc.htm] states:
This script extension is a core Site Studio method that allows any element within managed XML file to be extracted and returned in an Idoc string variable, which be placed directly on a web page as an HTML snippet. The content of the XML node that is being extracted will be further evaluated in the scope of the current layout and therefore can include further server-side Idoc Script, if necessary.
The parameters are:
- dDocName of XML data file
- XPath expression (to identify a specific node or nodes of the XML data file)
Do you know what implementation of the XPath language is used in Site Studio?
Is it a subset of the language (the Technical Reference does not mention this at all)? Which subset?
Here is another XPath expression that works perfectly well in JDeveloper and fails in Site Studio:wcm:root/wcm:list/wcm:row[child::wcm:element[@name='Key']/text()[.='FLAF_KEY_1']]/wcm:element[@name='Value']/node()Any insights are appreciated! :-)
