how to debug template rules?

gorgonz · Jan 9, 2004

since I'm not to familiar with xsl yet, I would like to do some kind of debugging. I want to understand it in a better way, which template rule created which kind of output. The hard coded way is something like this:

<xsl:template match="mybold">
{mybold}<b>
<xsl:apply-templates/>
</b>{/mybold}
</xsl:template>

It results in the additional debug braces {mybold} and {/mybold}

The disadvantage is, that I cannot switch it on or off. So I would prefer to have a global variable 'debug' with values on/off and a code snippet, that decides within any template, whether the debug braces are to be printed. Someone got an idea, how to do that - without being too complicated ;-) ?

thx again

Having the xml code:

Code:

<?xml version=&quot;1.0&quot; standalone=&quot;no&quot; ?>
<?xml-stylesheet href=&quot;bold.xsl&quot; type=&quot;text/xsl&quot; ?>

<container>
 this is <mybold>bold</mybold>
</container>

I tried this approach:

Code:

<xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform&quot;>[/URL]

 <!-- set global variable -->
 <xsl:param name=&quot;debug&quot;>on</xsl:param>

 <xsl:template match=&quot;/&quot;>
  <HTML> 
   <HEAD> 
    <TITLE>bold style</TITLE>
   </HEAD> 
   <BODY bgcolor=&quot;lightgreen&quot;> 
    <xsl:apply-templates/> 
   </BODY> 
  </HTML> 
 </xsl:template>

 <xsl:template match=&quot;mybold&quot;>

  <!-- test, if the global variable was set to 'on' -->
  <xsl:if test=&quot;$debug=on&quot;>
   <xsl:text>{</xsl:text>
   <xsl:value-of select=&quot;name()&quot; />
   <xsl:text>}</xsl:text>
  </xsl:if>
  <!-- end of debug tag -->

  <b>
  <xsl:apply-templates/>
  </b>

  <!-- test, if the global variable was set to 'on' -->
  <xsl:if test=&quot;$debug=on&quot;>
   <xsl:text>{/</xsl:text>
   <xsl:value-of select=&quot;name()&quot; />
   <xsl:text>}</xsl:text>
  </xsl:if>
  <!-- end of debug tag -->

 </xsl:template>

</xsl:stylesheet>

The bold rule works, but the 'if' condition is ignored. Is there an idea, why it will not work?
