& I’d like to split the records returned from it using the logic below:
If the xml file has 30 or more PROV-or-CLM-or-TOTATALS nodes then process only 30 PROV-or-CLM-or-TOTATALS nodes. Do this for the entire xml file in case where the number of remaining nodes is less than 30 process them to complete the transformation.
I’m using the following xsl to do this:

My current scenario is such that the split doesn’t work & I get the exception: Exception in thread “AWT-EventQueue-2” java.lang.OutOfMemoryError: Java heap space despite allocating -Xms/-Xmx2G memory.
Kamza, you had part of it right, but there are a few flaws in your approach. You start with a for-each on PROV elements, and within the for-each you have an if that causes output to be written only for PROV elements 1, 31, 61, etc. The nested for-each loops have a similar problem. Only CLM element 1, 31, 61, .. is written, like only TOTALS 1, 31, 61, ..
(Actually, I suspect there will only be one TOTALS within each PROV, so that would ok in your code.)
Furthermore, from what I understand from your description and the comments is that you are trying to write out 30 rows at a time, and start a new table, or even a new page after that, with another 30 rows, or what is left. Since no rows are written for the PROV element itself, I presume that it is just about CLM and TOTALS rows, where the count of 30 should include both.
What you need for that is an outer for-each loop that walks along all CLM and TOTALS elements. You can use this expression for that:
Then use the if you already have to create a new table for row 1, 31, 61, …
To fill the table with the first-next 30 items, you will need to look forward 30 positions. The PROV element is a bit of a problem here. Assuming CLM and TOTALS only occur within PROV, and PROV is not used elsewhere, you can reasonably safely use the following axis for that:
That returns 30 items, both CLM and TOTALS mixed, but in document order. You need two extra if’s (or a choose) to distinguish between these two, and output the appropriate table row:
In your code you have fo:table-body within the inner for-each loops, causing each table-row to be wrapped in a new table-body. That is unnecessary. Move the table-body to outside the inner loops. You would need only one wrapping both rows of CLM and TOTALS.
Finally, you write a new table for each 30th item. I think you want to start a new page-sequence as well. That will cause each table to be shown on a separate page. Putting things together, you get an XSLT similar to this:
Note: I am not entirely convinced this will prevent you from getting an exception. You gave the impression it is because of your for-each loops, but it may be caused by something else. A table that is simply to big, or an fo document that is too large to render might be the cause as well, for instance. The above code should be fairly efficient. If it is still giving you trouble, try processing things from the command-line, perhaps even using different parsers.
