Re: Fwd: Question about Gobo xml parsing library

Thank you Alexander and Collin!

My xml document is quite simple( prolog and main node ), with no DTD or CDATA.
That means the spaces in attributes' value should always be preserved, no matter the parser is validating or not.

It seems that Nenie xml parser should be corrected (it collapses the spaces and remove leading and tailing spaces unexpectedly.)
I intend to patch Nenie xml parser with the diff I find in 
gobo-eiffel.git.sourceforge.net/git/gitweb.cgi?p=gobo-eiffel/gobo;a=commitdiff;h=374c3367994f573e2699e9df7ccb9e9372196097

But that one is for gobo xml parser, although I find the code is almost the same with Nenie xml parser.
Do you know the history between these two parsers? 
And what's the better choice for me, patch Nenie xml parser, or replace the Nenie with gobo xml parser?

Thank you in advance.

And to spell it out, the Gobo XML parser is non-validating.
