Re: Grouping by key

Hi,

The suggestions Geert gave for the problem worked well regarding 
grouping/categorising.  I am trying to display only the categories or 
categories and records under that category using a parameter.  I have a 
xsl:param collapse and I want to use/apply some templates based on that 
param but the <xsl:if> element doesn't seems to be working.  I want to 
know whether the usage of if element is right or I can use the element in 
this context.  I have 

Here is the xsl file and I have used <xsl:if> element at 3 places (look 
for $collapse).  Please let me know whether you need the xml file or any 
other information regarding this.  Thanks.
