Re: [xsl] Can I change variable contents.

[Vikram Barate <vikram@xxxxxxxxxx>]

Thanx David,

<Tag value="X:Y">
</Tag>

In the example I've given my main problem is Xs and Ys in the value 
attribute are not known to me. It can be grade, sub or anything else. 
That is my main problem area. X and Y can be anything and I want to 
group all Ys according to existing Xs in XML and print.


Thanks,
Vikram
