Re: Grouping using concatenated key

<xsl:key name="byObligationAndPhone" match="BillDetail"
use="concat(OBLIGATION_ID, ':', PHONE_NUMBER)" />

All,

I have been wrestling with this problem for about 3 days now.  I have
looked at the examples that Jenni has provided, but I am just not getting
it quite right.

Here is some example XML that I am using:



<BillDetail>

</BillDetail>

These are just 2 dummied up records.  What I need to do is group these
records first by OBLIGATION_ID then by PHONENUMBER, and then display the
results.  Here is the key I am trying to use to accomplish this:

<xsl:key name="byObligationAndPhone" match="BillDetail"
use="concat(OBLIGATION_ID, PHONE_NUMBER)" />

I have tried looping through the XML using this key to no avail.  Could
someone steer me in the right direction?

Basically, here is what I am wanting to see:



Begin loop

Calls for OBLIGATION_ID

.

.

.

Calls for PHONE_NUMBER (that has the same OBLIGATION_ID from above)

End Loop

I need to loop through all <BillDetail> nodes, breaking it down by
OBLIGATION_ID, then beneath each OBLIGATION_ID, I need to break it down by
PHONE_NUMBER.

This is my first project using XSLTand I am enjoying it greatly.  If I
could only get over this one hump

Many thanks in advance,



JOHN
