[xsl] Illegal xml chars

["Waqar Ali" <waqarali_pk@xxxxxxxxxxx>]

Hello:

I have an illegal character in my xml (0x08 or ) and when I tries to 
transform it using xslt, the parser (MS .NET) gives me an error(hexadecimal 
value 0x08, is an invalid character). I tried everything: using different 
encoding, wrapping my xml data in CDATA tags but nothing seems
to be working. What do you suggest?

I may end up removing the illegal chars manually using a regular expression. 
Do you know one which can remove  and other illegal chars from the xml?

Thanks,
