Hello,
I am converting an XML to an CSV via an XSLT. Every thing is working but not the conversion of some characters. The XSL contains <xsl:output method="text"/>, but if the XML contains specefic characters like &amp; &gt; &lt; etc. they are not transfered to & < > like it shoul do.

Searching the forums I found some hints like this:

the most common error is that programmer's accidentally use:
DocumentFragment processXSL(xsl,xml)
instead of the:
void processXSL(xsl,xml,PrintWriter)
Only the latter gives the XSLT processor a chance to control the serialization and implement the <xsl:output> hints.

I am calling the function like this:
xsl := dbms_xslprocessor.newstylesheet(xsltdomdoc, '');
-- Get the new xsl processor instance
proc := dbms_xslprocessor.newProcessor;

-- Apply stylesheet to DOM document
outdomdocf := dbms_xslprocessor.processxsl(proc, xsl, indomdoc);
outnode := dbms_xmldom.makenode(outdomdocf);

I do not know, how to implement it with Printwriter.

Has anyone an idea?

Thanks
