Re: [xsl] How to generate an XML log using xsl:message?

[George Cristian Bina <george@xxxxxxx>]

Hi Stefan,

I think the solution depends on how you get the messages. For instance 
if you register a MessageEmitter for Saxon or an ErrorListener for Xalan 
to collect the messages then you can emit the root element when you 
serialize them. If you rely on the default message processing (that is 
on the fact that they are written to stderr then you can write the start 
tag before the transformation to stderr and after the transformation 
write the end tag.
If you are looking for a solution inside the stylesheet and all you want 
to do is to collect the stderr content then I cannot think (at least 
right now :) ) at a different solution than to use the 
disable-output-escaping attribute. Something like below:

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

    <xsl:template match="/">
        <xsl:message>
            <xsl:text disable-output-escaping="yes">&lt;log></xsl:text>
        </xsl:message>

        <xsl:message>
            <test>sample</test>
        </xsl:message>

        <xsl:message>
            <xsl:text disable-output-escaping="yes">&lt;/log></xsl:text>
        </xsl:message>
    </xsl:template>
</xsl:stylesheet>

should give you:

<log>
<test>sample</test>
</log>

Best Regards,
George
