Re: [xsl] Grouping and filtering

Bernard..
The following code will help you..
This XSL does both the sorting which you have asked for.
1. it prints the group name based on the item
2. it prints the group name based on the items starting with a string.
The first is fairly simple and the code is self explainatory
The second accepts a String parameter as a filter_string..
and does the filtering based on parameter.
The XSL is intended to output HTML format file
the code follows

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0">
<xsl:key  name = "groupname" match = "/groups/group" use = "item"/>
<xsl:param name="filter"/>
<xsl:template match="/">
<xsl:for-each select="/groups/group/item[not(. = preceding::item)]">
groups of item name : <xsl:value-of select="."/><br/>
  <xsl:for-each select="key('groupname',.)">
   <xsl:value-of select="@name"/><br/>
  </xsl:for-each><hr/>
</xsl:for-each>
<hr/>
groups of item name starting from <xsl:value-of select="$filter"/><br/>
<xsl:for-each select="/groups/group/item[(not(. = preceding::item)) and 
(starts-with(., $filter))]">
Name:<xsl:value-of select="."/><br/>
  <xsl:for-each select="key('groupname',.)">
   <xsl:value-of select="@name"/><br/>
  </xsl:for-each><hr/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Hope this helps
