Time exceeded when uploading file content is usually related to the
client upload time required to get the content onto the server - PHP5
uses Libxml for processing and XSL work, which is very fast.

You should check not only the max_execution_time, but also the php.ini
setting for max_input_time, which refers to the upload duration :
http://uk.php.net/manual/en/info.configuration.php#ini.max-input-time

Those settings are distinct, separate timeouts. 

Note that if you're using the XSL extension then you're working with
DOM which creates the structure in memory - make sure you have enough
memory allocated to PHP to process the nodes in a 20MB input document.

Another approach would be just to accept the file upload, flag the
file content as a DB record "to process" and do the processing out of
band as a scheduled task / cron job on a beefier backend server.
