RE: [xsl] Collect word count with xslt2.0 on saxon 8

Hi George-

Thanks for the code sample. I would like to better understand how this 
apply-templates works-
   <xsl:template match="*[contains(@class, 'topic/topic')]"
     mode="getText"/>
       <xsl:apply-templates mode="getText" select="node()"/>

It seems that the template rule would remove the node from the source at the 
processing context yet with the apply templates it actually retrieves it- could 
you elaborate on this approach - I also need to remove from the node comment 
elements  before I count the text contents of the node -

If I add an template 
<xsl:template match="draft-comment"  mode="getText"/>

I get  -
BUILD FAILED
java.lang.StackOverflowError

( I am building with Ant but this is an xsl related error . )

Hello Karen,

You can get the count of words more easily than that. First you can get 
the text in a variable that belongs to an element with topic/topic but 
not to other elements inside it with the same mark and then just count 
the words in that.
For getting the text once we match on a topic/topic element we use a new 
mode for apply-template on which we do nothing on elements with 
topic/topic thus we exclude their text content.

The following stylesheet shows that

<xsl:stylesheet version="2.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:output indent="yes"/>
   <xsl:template match="/">
     <counts>
       <xsl:apply-templates/>
     </counts>
   </xsl:template>
   <xsl:template match="text()"/>
   <xsl:template match="*[contains(@class, 'topic/topic')]">
     <xsl:variable name="text">
       <xsl:apply-templates mode="getText" select="node()"/>
     </xsl:variable>
     <record>
       <text>
         <xsl:value-of select="$text"/>
       </text>
       <count>
         <xsl:value-of
 
select="count(tokenize(lower-case($text),'(\s|[,.!:;]|[n][b][s][p][;])+')[string(.)])"
         />
       </count>
     </record>
     <xsl:apply-templates/>
   </xsl:template>

   <xsl:template match="*[contains(@class, 'topic/topic')]"
     mode="getText"/>
</xsl:stylesheet>
