XSLT to Python script conversion?

[Matej Cepl]

Hi,

I am getting more and more discouraged from using XSLT for a 
transformation from one XML scheme to another one. Does anybody could 
share any experience with porting moderately complicated XSLT stylesheet 
(https://gitorious.org/sword/czekms-csp_bible/blobs/master/CEP2OSIS.xsl) 
into a Python script using ElementTree's interparse or perhaps xml.sax?

Any tools for this? Speed differences (currently I am using xsltproc)? 
Any thoughts?

Thank you,

Matěj
