Re: [xsl] looping problem, <xsl: for-each>??

[Mukul Gandhi <mukulgw3@xxxxxxxxx>]

Hi James,
 This is a grouping problem, which can be solved by
the Muenchian method. Please try the following XSL --

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
   <xsl:key name="x" match="/rss/channel/item"
use="category" />
   
    <xsl:template match="/">
      <xsl:for-each select="rss/channel/item">
	<xsl:if test="generate-id(.) = generate-id(key('x',
category)[1])"> 
         <h1>
            <xsl:value-of select="category" />
         </h1>             
	 <xsl:for-each select="key('x', category)">	  
ITEM<!-- ?? -->  <xsl:value-of select="description"/>
	 </xsl:for-each>
       </xsl:if>
     </xsl:for-each>
   </xsl:template>

</xsl:stylesheet>

You want the labels to be output as -- ITEM1, ITEM2,
ITEM3, ITEM 4. I cannot think of a good way to do
this. <!-- ?? --> part of my XSL needs to be
completed.

Something using position() and count() should be
required..

As I requested earlier also on the list --
If there is a feature to increment a variable (not the
present xsl:variable! , as it operates on many things
like tree fragments etc.) , it would be convenient to
perform just the same thing as required here.. 

But its very difficult to introduce the variable
incrementing in XSLT, as it would radically change the
nature of XSLT processing. 

Is something thought of *to fulfill this kind of
requirement* ? 

Regards,
Mukul
