Documentation of xalan error messages

[SP/Nowotny Florian <fn...@vfst.de>]

Hi,
I need a documentation of the error messages of C++ - Xalan 1.4 (and Xerces 2.1).
Can anybody tell me where to find one?

I would like to know all the reasons for xalan to raise the message "the primary document entity could not be opened"?
One is when I use a filename in one of the two contructors of XSLTInputSource (ether the XML or XSL document) is not acessible/availible, correct?
Does it also occur when I use istreams that are corrupt in any way? 

When exactly does Xalan raise "invalid document structure"?
I'm using an istream as the InputSource for xml. I get this message even though the get pointer of the stream is at ios::beg position.

Hi Florian,

Unfortunately, those are both Xerces-C error messages, and not Xalan-C
error messages.

The first occurs when any document entity cannot be opened by the parser.
That usually means you've supplied a file name, or a URL.  It should not
happen when using a std::istream, because the parser is not trying to
"open" the entity.

An "invalid document structure" error would occur whenever the parser
cannot make sense out the byte stream it is parsing.  That can include:

   1. spaces before the xml declaration, or the document element, if
   there's no xml declaration
   2. non-whitespace characters outside of the document element
   3. A mismatch in the encoding declaration and the actual encoding of the
   document.

You should dump the bytes in your input stream and verify you actually have
a well-formed XML document.  If your platform is Solaris, there is a known
bug with IOstreams on that platform which results in a corrupt stream.  If
that's the case, there's a patch from Sun you can apply to fix the problem.
