Hi Marina,
If you will overload the XSLT processor, *it is bound
to take time*. The process may even hang(as you are
reporting). An XML file of size 18.1Mb will certainly
take lot of resources. If possible you may split the
original XML file into smaller ones, and then apply
XSL to the smaller files. It may run fast.
If you can give more details about your XML and the
XSL you are trying, probably somebody can give you
ideas to improve performance of the transformations.
Regards,
Mukul

Hi,
I am having problems parsing some xml files.I have a
1ghz processor and 256Meg Ram.
The xslt stylesheet "wordgroup.xsl" from Dimitri
(thankyou!) wwas tested
and worked perfectly on smaller test files. When I
run
it on a larger file
"1cl.xml" = 18.1Mb it builds the tree for
str-Split-to-words.xsl and then sits there for
hours.
See output below.

So I made another xml file "little.xml" by pasting
sections of 1cl.xml in different sizes to see
where it was having problems processing.
little.xml = 1.4Mb time = 1.2sec
little.xml = 4.4Mb time = 3.3 sec
little.xml = 7.3Mb time = 6 sec
little.xml = 10.3Mb time = 9.8 sec
little.xml = 19.2 Mb (bigger than the file I want to
parse!) time = 26.1 sec! (see nice output
below)

Any ideas for me to try?
