RE: [xsl] Counting nodes processed

[JAY SCHERER <jay dot scherer at adtran dot com>]

Joerg,

well, i need to keep up with a running total of the number of topics printed.  Here's some xml and I only want to print a total of 4 topics.

<Category value="category1">
  <topic value="topic1-1"/>
</Category>
<Category value="category2">
  <topic value="topic2-1"/>
  <topic value="topic2-2"/>
</Category>
<Category value="category3">
  <topic value="topic3-1"/>
  <topic value="topic3-2"/>
</Category>

Output should be
Category1
  topic1-1
Category2
  topic2-1
  topic2-2
Category3
  topic3-1

Notice topic3-2 has been eliminated.

I don't want the total to apply per category, I want it to be a sum of all the topics printed.

Jay

Hello Jay,

if you want to process the category nodes, why you go directly to the 
topic nodes?

<xsl:template match="root">
	<xsl:apply-templates select="category"/>
</xsl:template>

<xsl:template match="category">
	<xsl:value-of select="@value"/>
	<xsl:text>&#10;</xsl:text>
</xsl:template>

<xsl:template match="topic">
	<xsl:text>    </xsl:text>
	<xsl:value-of select="@value"/>
	<xsl:text>&#10;</xsl:text>
</xsl:template>

In general it's bad coding to use //. Try to specify the path more exactly.

Regards,

Joerg
