Re: element names

Hey,
      Sorry, I should have made that clearer. Jesse is completely 
correct. If you need tips of how to implement then feel free to give me 
a shout.

Nor does it seem likely that such a change will be made to the official
code. Xerces implements standards, which makes it predictable and
relatively easy to maintain. If such non-standard behavior is a
requirement, I think you'll have to make your own modifications.

Hi,
I cannot think of a way of doing this without changing the code base.

Hi everyone,
I have a rather silly question:
Is there a workround if I want to be able to use numbers as 
     

element names?
   

I'm writing a WebDAV client libray, which uses Xerces-C to parse XML
response from different servers. Some days ago someone wrote me and
complained that my library kept raising DOM exceptions while he was
trying to connect to a MS Exchange2000 server. It turned out that
Exchange2000 is using some element names like "0x001a". It 
     

is obviously
   

a violation to XML specification. But since Xerces-C is quite a big
library, I think chances are there might be a way to live 
     

with this MS
   

reality.
I use XercesDOMParser as my parser so I checked the 
     

documentation. But
   

to my dissapointment, there is no such method in Grammar to 
     

bypass name
   

check. And the exception turned out to be raised from
DOMDocumentImpl::isXMLName() which in turn calls
XMLChar1_0::isValidName(), nothing related to Grammar. Here 
     

is a stack
   

trace showing where and how the exception is raised:

Can anyone tell me if it's possible? Any clue or hint?
Thanks a lot.
