[xsl] replacing special characters in xsl:copy

2007-06-06 09:37:51
Hello all,
I'm just beginning to get into XSLT 2.0 and I'm trying to copy the XML
source to an HTML report; what I would like to do is replace "<" and ">"
in the copied source with "&lt;" and "&gt;".

The soure looks similar to:

  <task location="L:\\build-log.xml:48: " name="foo" time="0 seconds">
    <message priority="warn"><![CDATA[ Text warning of foo ]]></message>
  </task>

What I've got so far is this:

<xsl:output method="html" indent="yes"/>
  <xsl:template match="/">
  <html>
    <body>
        <xsl:for-each select="for $f in collection
        
('file:///c:/temp?select=*.xml;recurse=yes;on-error=ignore')  return  
            saxon:discard-document($f)">
                <xsl:choose>     
                  <xsl:when test="//message[(_at_)priority='warn']">
<h2>Warning in <xsl:value-of select="document-uri(.)"/>:</h2>
<pre>
   <xsl:copy-of
select="replace(//message[(_at_)priority='warn'],'&lt;','&lt;')"/>
</pre>                  
                 </xsl:when>
                 <xsl:otherwise>
<h2>No errors or warnings in <xsl:value-of
select="document-uri(.)"/></h2>
                 </xsl:otherwise>
        </xsl:choose>
   </xsl:for-each>
    </body>
  </html>
</xsl:template>


What my desired output would be is:

<h2>Warning in file:/c:/temp/foo.xml </h2>
<pre>
  &lt;task location="L:\\build-log.xml:48: " name="foo" time="0
seconds"&gt;
    &lt;message priority="warn">&lt;![CDATA[ Text warning of foo
]]&gt;&lt;/message&gt;
  &lt;/task&gt;
</pre>

Is what I'm trying to do possible?  Am I on the right track?  Any
suggestions gratefully received.

TIA,
John
