Thanks, I figured out alot by reading. Just need to know how to display records by grouping example by Category Name in this xml? will be using key?

Below is my sample xml file,
header>
<groups ver="0">
<group name="Options" ID="1" GID="01">
<categories>
<category ID="10" name="Options" CID="10">
<mitems>
<Item cost="0.0" ItemName="No" notes=" " price="0.0">
</Item>
</mitems>
</category>
</categories>
</group>
<group name="Options" ID="1" GID="01">
<categories>
<category ID="10" name="Options" CID="10">
<mitems>
<Item cost="0.0" ItemName="No" notes=" " price="0.0">
</Item>
</mitems>
</category>
</categories>
</group>
</groups>
</header>

The Wrox books on XSLT explain these concepts carefully with many examples. If you have problems with the explanations in the books, by all means ask for clarification. But I get the impression that you are using this site as a substitute for the book, not as a supplementary resource
