Thanks heaps Ken, I was really thinking of it the incorrect way.
This taught me a lot. Thanks!

I'm trying to do a simple grouping and then post the siblings but I'm
a little bit confused.
I have the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<Entries>
<entry>
<First>First Group</First>
<Second>sample data I</Second>
</entry>
<entry>
<First>Second Group</First>
<Second>sample data II</Second>
</entry>
<entry>
<First>First Group</First>
<Second>sample data III</Second>
</entry>
</Entries>
I'm trying to group the data using the <First> tag and then show all
the <Second> tags data.
Example of the result:
<Entries>
<entryTransformation>
<data>First Group</data>
<secondaryData>sample data I</secondaryData>
<secondaryData>sample data III</secondaryData>
</entryTransformation>
<entryTransformation>
<data>Second Group</data>
<secondaryData>sample data II</secondaryData>
</entryTransformation>
</Entries>
I'm using
<xsl:for-each-group select="/Entries/entryTransformation/data"
group-by=".">
To make the grouping, but then I don't know how to iterate the
<Second> elements.
You've got your perspective backwards by trying to address nodes in the
result tree, when you must always address nodes in the source tree.
I hope the example below helps.
