Saxon XSLT and XQuery Processor

Hi Folks,

I have a  stylesheet which uses xsl:namspace-alias.  When I run SAXON
7.5.1 from the command line the stylesheet works fine.  When I run it
from my Java application the result namespace prefix is incorrect.

Here's my very simple stylesheet:
-----------------------------------------------------------------------------------------------------

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:axsl="http://www.w3.org/1999/XSL/TransformAlias"
                version="1.0">

    <xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl"/>

    <xsl:output method="xml"/>

    <xsl:template match="/">
        <axsl:stylesheet version="1.0"/>
    </xsl:template>

</xsl:stylesheet>
-----------------------------------------------------------------------------------------------------

When I invoke SAXON from the commend line I get this (correct) output:

-----------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"/>
-----------------------------------------------------------------------------------------------------

When I invoke SAXON from my Java application I get this (incorrect)
output:

-----------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<axsl:stylesheet xmlns:axsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"/>
-----------------------------------------------------------------------------------------------------

Note that the result namespace prefix is incorrect.

My Java program uses the TRAX API.  Here's the method that I invoke:

    public String doTransform(String xml, String xsl)
    throws TransformerException, TransformerConfigurationException,
           FileNotFoundException, IOException {

       TransformerFactory tFactory = TransformerFactory.newInstance();
        StringReader xsl_sr = new StringReader(xsl);
        StreamSource xsl_ss = new StreamSource(xsl_sr);
        Transformer transformer = tFactory.newTransformer(xsl_ss);

        StringReader xml_sr = new StringReader(xml);
        StreamSource xml_ss = new StreamSource(xml_sr);
        StringWriter out_sw = new StringWriter();
        StreamResult out_sr = new StreamResult(out_sw);
       transformer.transform(xml_ss, out_sr);

        return out_sw.toString();
    }

and here are the classes that I import:

import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerConfigurationException;

Am I doing something incorrect?  /Roger

I need regex capability of the type provided by
the java regex Matcher and Pattern classes. In
particular I need to obtain the number of matching
groups from the regex and the portion of the
original string which matched. ( analyze-string
does not provide this). Also, I do not know in
advance what the regex is (separate XML source).

Sometime back there was a thread on the XSLT list
on using the java regex and ORO matcher classes, 
but I can't get these to work as advertised. Is
it better to create my own java wrapper to provide
a better interface to work from within XSLT or
how are others using regexs in Saxon ?


Kind regards, John.
