Re: [xsl] MSXML DOCTYPE error

["Luke Stedman" <luke.stedman@xxxxxxxxx>]

Thanks Martin,

The fix worked perfectly.

For anyone interested the fix was to change...
--------------
xslFile = win32com.client.Dispatch("MSXML2.FreeThreadedDOMDocument")
if not xslFile.Load(xslFileName):
		raise ValueError("Failed to load file '%s'" % (xslFileName))
--------------

To:
--------------
xslFile = win32com.client.Dispatch("MSXML2.FreeThreadedDOMDocument")
xslFile.validateOnParse = False
if not xslFile.Load(xslFileName):
		raise ValueError("Failed to load file '%s'" % (xslFileName))
--------------

Thanks a lot!
Luke
