XPath Expression won't evaluate

Question

Hi,
I am using the ora:doc() function to read an xml and XPath to get extract particular values from it. The issue is that the XPath expression doesnt evaluate correctly on Oracle BPEL process manager where as the same expression is being evaluated correctly in XMLSPY with XPath 1.0.
The XML that I am trying to read is of the format
<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2006 U (http://www.altova.com)-->
<n:CHNotification xmlns:n="http://www.example.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.example.org
C:\OraBPELPM_1\integration\jdev\jdev\mywork\BPELWorkspace\testXML\CallHomeNotification.xsd">
     <Notification id="String">
          <n:mailto>String</n:mailto>
          <n:mailcc>String</n:mailcc>
          <n:subject>String</n:subject>
          <n:body>String</n:body>
          <n:additionalbody>String</n:additionalbody>
     </Notification>
     <Notification id="String32432">
          <n:mailto>String</n:mailto>
          <n:mailcc>String</n:mailcc>
          <n:subject>String</n:subject>
          <n:body>String</n:body>
          <n:additionalbody>String</n:additionalbody>
     </Notification>
</n:CHNotification>
The function being used in OracleBPEL Process manager is
ora:doc('${server_url}/xmllib/notification.xml', //Notification[@id="String"]/n:mailto)
Can somebody please tell me where I could be going wrong?....It'll be a great help.
Thanks,
Gunjan

I have the same problem posted in the constants discussion
Hi
I am trying out the xml file solution. I have places an XML-file in the xmllib location. The file has the following content :
<?xml version="1.0" encoding="UTF-8">
<bpel-domain>
<preferences>
<property name="defaultRentepercentage"> 0.3 </property>
</preferences>
</bpel-domain>
In the Assign step in BPEL I do the following
orcl:lookup-xml('http://localhost:9700/orabpel/xmllib/trials-properties.xml', '/bpel-domain/preferences/property[@name="defaultRentepercentage"]')
The error I get when running this is the following
XPath expression failed to execute.
Error while processing xpath expression, the expression is "orcl:lookup-xml("http://localhost:9700/orabpel/xmllib/trials-properties.xml", "/bpel-domain/preferences/property[@name="defaultRentepercentage"]")", the reason is ExtFuncFunction.
Please verify the xpath query.
I have tried the xpath expression in XMLSpy, and there it seems to work
Am i missing something ?
