[xslt] stream xsl

[Utkarsh Shah <ushah wmotion com>]

Hello list,
          I have encrypted xsl files. So before initializing 
xsltStylesheetPtr I have to decrypt the file contents block by block 
i.e. I will have to read the encrypted XSL file buffer after buffer 
decrypt that buffer and then some how get xsltStylesheetPtr to that 
whole XSL stylesheet. I can't create a temporary decrypted XSL file. So 
I was wondering if there is a way I can achieve this. I looked at 
example available on this url,

http://www.xmlsoft.org/examples/index.html#reader1.c

Will I have to go this route, or there is a better way?
Thanks,
Utkarsh
