Thank you Frank. It's really helpful. -----Original Message----- From: Franck Arnaud [mailto:fr...@ne...] Sent: Wednesday, September 07, 2011 8:31 PM To: Godo Develop Subject: Re: [gobo-eiffel-develop] Fwd: Question about Gobo xml parsing library Hi, Yes you should use Gobo's XML library, whose code started with Nenie XML many years ago, and Nenie XML hasn't been maintained since it moved to Gobo. I'm almost surprised it still works at all on current compilers after all those years :-). I think Alexander is on the thing re the reason, I don't recall the exact details but I had read something wrong from the standard on normalization and fixed it once it was in Gobo (actually I think there might be some remaining issues in that area, either of inelegant implementation or some obscure normalisation case that you don't actually hit in real life, or something). Well done with the detective work btw ;-).
