How to use split , rex or xtree

[nairjitish]

This is what I wanted to do :
I have a variable ie :
$xyz=abc;bvkxf;dcvjsd;shvc
I want to split this variable by ';' and loop throught the text.
ie :
I want to process abc, bvkxf... individually by placing it in a separate variable.
I am not sure of how many ';' separated values are there. It can change.

<$xyz="abc;bvkxf;dcvjsd;shvc">
<split row ";" $xyz>
item $loop="$ret"
</split>
