awk substring

My problem:
I have a flat text file that has to be transformed into a predetermined XML

Example:
TYPE1Field1AnotherField12.00YetAnotherField445.26FinalField
TYPE1ABCDEFABCDEFGHIJKL45.00ABCDEFGHIJKLMNO123.45ABCDEFGHIJ
TYPE2FieldAnother987.65Final

where the first 5 characters indicate which one of two record layouts it is.

I need to total up certain numeric values within the record of a specific
layouts.
For example, I want to total up the values that occupy positions 24 thru 28
from all records of "TYPE1".

MHO, this is really the realm of a flat-text processing program like awk or perl. You have a wonderful XSLT hammer, but you're trying to use it on a screw. Use awk to grind the threads off the screw & make it into a nail that you can pound on with XSLT. :-)

(I would post an entire awk script but it would be off-topic.)

Is there any way of doing this?

An awk script could handle that too. You could create a <total> element containing the sum at the end.
