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

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>

on your sample input it gives:

<?xml version="1.0" encoding="UTF-8"?>
<counts>
   <record>
      <text>
     communications and information theory
     top element
     elements can be nested Generalized Markup

  </text>
      <count>17</count>
   </record>
   <record>
      <text>
       communications and information theory
       top element
       elements can be nested (for a number of
      technical reasons beyond the scope of this article).
    </text>
      <count>22</count>
   </record>

        not well

      <count>29</count>
   </record>
</counts>

I have the following structure that i need to collect word counts for from each element that has a class attribute that contains " topic/topic " without counting its child elements that also contain the the class attribute " topic/topic "

I have this template that gets the word count for each
element and its child elements including the elements
that have class attributes that contains "
topic/topic ".
 <xsl:template match="*[contains(@class, 'topic/topic
')]">
 <xsl:variable name="level"
select="count(ancestor::*[contains(@class,
'topic/topic ')]) + 1"/>
 <xsl:variable name="ct" select="if ($level =
1) then concat(title,' ') else ' '"/>
 <xsl:variable name="h1" select="if ($level =
2) then concat(title,' ') else ' '"/>
 <xsl:variable name="h2" select="if ($level =
3) then concat(title,' ') else ' '"/>
 <xsl:variable name="h3" select="if ($level =
4) then concat(title,' ') else ' '"/>
<xsl:variable name="wc" select="count(tokenize(lower-case(.),'(\s|[,.!:;]|[n][b][s][p][;])+')[string(.)])" />
 <xsl:apply-templates/>
 </xsl:template>
I added another template that contains the count of
its child elements b
<xsl:template match="*[contains(@class, 'topic/topic ')]" mode="filterCount"> <sum> <xsl:value-of select="count(tokenize(lower-case(.),'(\s|[,.!:;]|[n][b][s][p][;])+')[string(.)])"/> </sum> </xsl:template>
That I store in a variable and then subtract from the
total within in the first template above
<xsl:variable name="childcounts"> <sums> <xsl:apply-templates mode="filterCount"/> </sums> </xsl:variable>
 <xsl:variable name="total-child"
select="sum($childcounts/sums/sum)"/>
 <xsl:variable name="total-roman"
select="sum($wc - $total-child)"/>
I would like to find a more elegant approach to this
because there are also other attributes in this
content that need to have the same technique applied
to b
Would it be a better approach to copy the elements to
another document node and then perform the word count
which would be applied recursively to all child
elements to arrive at the count and what would this
template match look like?
