Error BEA-382510 bad value for type node

Question

Hi,
We have a requirement to read the xpath from the resource file placed in project folder in OSB and use that xpath to generate the report. For this I have done the following:
1) Made the xpath entry to properties file as <xpath>$body/*/*/EMPTYPE/EMPDATA/EMPNO</xpath>
2) Created a variable to fetch the xpath value from property file, say xpathvar
3) Created another variable, say reportvar which will have the contents: <report>{$xpathvar/text()}</report>. This should fetch the xpath from the variable and replace it in the calling part to fetch the value of the xpath.
4) For report generation the in key value it is ./text() from variable reportvar.
When I test this it throws error:
<con:errorCode>BEA-382510</con:errorCode>
<con:reason>
OSB Assign action failed updating variable "reportxpath": com.bea.wli.common.xquery.XQueryException: Error parsing XML: line 1, column 19: {err}XP0006: "$body/*/*/EMPTYPE/EMPDATA/EMPNO ({http://www.w3.org/2001/XMLSchema}string)": bad value for type node
</con:reason>
Any pointers will be highly appreciated.
Thanks!

I think you cant substitute xpath as you have did.
As shown in the blog which you mentioned in the other post you may need to have a xslt transformation with xalan:evaluate to correctly process the xpath read from the properties file.
<report>{$xpathvar/text()}</report>. Here $xpathvar having the value '$body/*/*/EMPTYPE/EMPDATA/EMPNO' will be treated as string type (this will be string as you have read from the properties file as string) and not node. And you are trying to apply the text() function on a string instead of node which is resulting in that error.
