Hi,

my aim is to return xml-nodes from a logicsheet, or more precise from the esql-logicsheet in my own logicsheet.

My logicsheet that doesn't work:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xsp="http://apache.org/xsp"; xmlns:foo="http://foo.bar/esql"; xmlns:esql="http://apache.org/cocoon/SQL/v2"; version="1.0">
<xsl:template match="xsp:page">
<xsp:page>
...
</xsp:page>
</xsl:template>

       ...

       <xsl:template match="foo:simplexmlreturn">
           <xsp:expr><returnnode/></xsp:expr>
       </xsl:template>

    <!--
    <xsl:template match="foo:esql">
           <xsp:expr>
        <esql:connection>
            <esql:pool>mysql-pool-test</esql:pool>
            <esql:execute-query>
                <esql:query>SELECT name From mytable</esql:query>
                <esql:results>
                    <table>
                        <esql:row-results>
                            <name>
                                <esql:get-string column="name"/>
                            </name>
                        </esql:row-results>
                    </table>
                </esql:results>
                <esql:no-results>
                    <error>Sorry, no results!</error>
                </esql:no-results>
            </esql:execute-query>
        </esql:connection>
            <xsp:expr>


I assume you mean </xsp:expr> here.

    </xsl:template>
       -->
        ...

</xsl:stylesheet>

If I only use the foo:simplexmlreturn-template, I don't get any XML-output in my XSP-Page.
Question 1: How do I return XML? Couldn't find any documentation on this.

If I uncomment the foo:esql-template the logicsheet crashes.
Question 2: How can I use the esql-logicsheet in my own logicsheet and return the resulting xml?

Cheers
Jonny

Normally an XSP-page (with or without a logicsheet) does return XML, that is, it emits XML (as SAX events) that travel down the pipeline to the following transformer or serializer.
It seems like you don't need the <xsp:expr> wrappers in the above code. If you remove them, does it work?
