mary jSubject: Looping more than one time through same node
Author: mary j

I have a problem in looping in xslt.
It is simple while performing in java but here, in xslt, I have a root node and inside that 4 nodes :

<Rate Guests="2" Units="1" Code="CP" Room="DLX">
<Rate Guests="2" Units="1" Code="RAC" Room="DLX">
<Rate Guests="3" Units="1" Code="CP" Room="DLX">
<Rate Guests="3" Units="1" Code="RAC" Room="DLX">

Now, I need to traverse in all these nodes and check @Code and @Room values which must be same.
Then, I need to add @Guests and @Units values.
I will exclude those nodes with @Code="RAC"

So, my result set will only be a single node like this:

<Rate Guests="5" Units="2" Code="CP" Room="DLX">

All others need to be deleted.

Hope you understand the problem.
Please give your suggestions urgently.

Hi Mary,
this is the usual grouping problem: have a look at http://www.jenitennison.com/xslt/grouping/index.html for a set of possible solutions.
