XSLT/XSL issue

I am trying to code this xsl stylesheet and not having done this before, I am lost. I do not have access to the actual xml being returned but do have access to the SQL Server procedure results that eventually ends up as the xml. The SQL Procedure returns several tables but I am really only concerned about two of them. LineItem and SubLineItem. What I need to do is filter the LineItem table down using a description.

<xsl:for-each select="//GetOrderDetailsInfoResults/LineItem[perf_desc != 'OPA Handling Fee']">

Now what I need to is to grab the value of an element (li_seq_no) out of these results. Use the returned "li_seq_no" to filter my SubLineItem and sum the due_amt element into a variable.

I have know idea how to do this. In sql server, this would be just a join such as

Select sum(sl.due_amt) from LineItem as l join SubLineItem sl on l.li_seq_no = sl.li_seq_no where l.perf_desc = 'OPA Handling Fee'

Any Ideas?
Thanks

what you should do is index the source (in order for us to help you a view on the source XML would really be nice)
indexing can be done with
<xsl:key>
give the key a random name, choose what element from the source should be returned and the index is the path to the li_seq_no
then you can get the indexed node back by calling the key function

inside the for-each for the LineItem, you can get the lis_seq_no
the key is for sublineitem
so
<xsl:key name="sli" match="SubLineItem" use="li_seq_no"/>

using the function inside the for-each
key('sli', li_seq_no) will return to you tyhe sublineitem nodes that match

XML source would help to be more precise

xsl:key is an index in the document
given two tables in one XML document, xsl:key is an enabler for joins
