Re: [Xalan C] Reading Stylesheet from a string

[Andy Hird <an...@myinternet.com.au>]

Hi Dave, Sorry took so long to get back to you (been distracted!).

Anyway - I tried the latest builds of Xalan/Xerces with my program which
attempts to load a stylesheet and XML document from a string and
then transform (should I be using Xerces from CVS with the current Xalan?). I
get a new error from my attempts to load a stylesheet from a string (well const
char *). This is all on Linux (Debian Linux 2.2 kernel - with gcc 2.95.2)

processStylesheet is now returning:

XMLException Type is : XMLPlatformException
Message is : Could not determine base pathname of the file

I've attached a sample program which reproduces this. Any insights would be
gratefully received.

Thanks
Andy
