Hi,
I tried using the approach in the below FAQ (
http://www.orbeon.com/community/faq#2.21 ) for converting an XML string
returned by an EJB into an XML document using the saxon:parse function -
however I get the error:
org.orbeon.saxon.xpath.DynamicError: An empty sequence is not allowed as
the first argument of saxon:parse()
The XML string returned by the EJB is
<?xml version="1.0"?>
<document>
<xml-string>
<name>Joe Bloggs Junior</name>
</xml-string>
</document>
The XPL code is:
<p:processor name="oxf:xslt">
<p:input name="data" href="#ejb-data" />
<p:input name="config">
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:copy-of
select="saxon:parse(xs:string(/document/xml-string))"/>
</xsl:template>
</xsl:stylesheet>
</p:input>
<p:output name="data" id="transformation-result"/>
</p:processor>
Stack trace is listed below.
Any help appreciated,
Regards,
Avinder Bahra

Easy task for me, that's in the FAQ:
