Performance question : what is the fastest way ?

[MAHE Vincent FTRD/DIH/REN]

Can anyone tell me what is the fastest way to process one unique XML file
against several XSL files.
I mean, I want to process the same XML file with different XSL files (and I
have a lot of them !).

How can I parse the XML file just once and then use always the same object
with my Transformer ?

Thanks.
