RE: [xsl] file_size_affecting_transformation??

[juan valentín-pastrana <jvalentin@xxxxxxxxxx>]

I had the same problem when processing a 200 MB file with more than 50000
first level tags in a 512 MB machine

same happened -out of memory error- when using windose xsltproc

I overcame it making a xsl preprocessing in order to reduce the xml
complexity, by removing some attributes and unused tags, it may help

The most likely explanation is that there is something in the logic of your
stylesheet code (an XPath expression somewhere) that doesn't cater for the
possibility of finding more than one polygon in the input. It's very
unlikely to be anything to do with document size: this could slow down the
transformation, or cause it to fail with an OutOfMemory error, but wouldn't
cause it to produce wrong results.
