Question

I am trying to use XSLT to generate a dynamic class based on the number of groups it finds in the XML. For example there will be X groups in the XML, all with child nodes. I need the for each loop to dynamically create a class name based on which group number it is in the list. I can populate the group name without a problem, but I can’t find any clear information of how to append the system generated part to the class.
For example:

• groupblue class = “groupblue-1”
• grouporange class = “grouporange-2”
• groupred class = “groupred-3”

Etc etc, for every group in the XML.

I hope this makes sense and someone is able to help! Thanks in advance.

EDIT:

XML

<group>
  <title>Title Content</title>
  <text>Content 1</text>
</group>
<group>
  <title>Title Content</title>
  <text>Content 2</text>
</group>
<group>
  <title>Title Content</title>
  <text>Content 3</text>
</group>

HTML output

<div id="titlecontent-1">
  text from group 1 content
</div>
<div id="titlecontent-2">
  text from group 2 content
</div>
<div id="titlecontent-3">
  text from group 3 content
</div>

This transformation:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="group">
     <div id="{translate(title, ' ', '')}-{position()}">
       <xsl:value-of select="text"/>
     </div>
 </xsl:template>
 <xsl:template match="text()"/>
</xsl:stylesheet>

when applied on this well-formed XML document (that wraps the provided XML fragment into a top element):

<t>
    <group>
        <title>Title Content</title>
        <text>Content 1</text>
    </group>
    <group>
        <title>Title Content</title>
        <text>Content 2</text>
    </group>
    <group>
        <title>Title Content</title>
        <text>Content 3</text>
    </group>
</t>

produces the wanted result:

<div id="TitleContent-1">Content 1</div>
<div id="TitleContent-2">Content 2</div>
<div id="TitleContent-3">Content 3</div>
