Avinder,
This doesn't look right. This is not a well-formed XML document. It is a document with an XML declaration all right, but then it's only character content (the brackets are escaped).
Maybe Alex can comment on how this could happen?

Hi,
When I redirect the output produced by the EJB to file via the file-serlializer processor, I get a file that reads:
<?xml version="1.0" encoding="utf-8"?> <document> <xml-string> <name>Joe Bloggs Junior</name> </xml-string> </document>
This XML string looks OK which is why I do not understand saxon:parse error. PS I am running under JBoss outside of OXF studio which I why I can not use the debug facility.

My guess is that... the first argument of saxon:parse() is an empty sequence, as the error implies. You are selecting /document/xml-string on the ejb-data document. Does it actually contain that? I.e., if you put a debug on <p:input name="data" href="#ejb-data" />, what do you
get?

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

What I want to do is to call an EJB method to return XForms instance data. The approach I was thinking of was to return the XML as a

However I can not see how I would be able to convert the string (returned as the output of the Dispatch processor) into an XML
document
for consumption the next pipeline processor.
Easy task for me, that's in the FAQ:
