Re: [xsl] coping with huge xml-saxon

["XSL Chatr" <xsl_chatr@xxxxxxxxxxx>]

Thanks Tom
My XML is a business critical file and it needs to be converted to various
forms like html text or RTF files.
Its interesting you mentioned that XSLT may not be the right solution. What
else would you think of  for a business that needs this kind of requirement
to be solved? Like conversion of XML to multiple files?
Thanks
