DTD parser doesn't handle colons (:) in elements and attribute names.
For example, the XML I'm trying to parse is here:
http://www.soapuser.com/basics3.html

It contains element names like SOAP-ENV:Envelope and attribute names like
xmlns:xsi.

I wrote a DTD for it but if an element or attribute in the DTD contains a
colon, Wireshark fails to load it with error message:
Dtd Parser in file my.dtd: syntax error in my.dtd:6 at or before 'Envelope': 
DTD parsing failure
syntax error at end of fileDTD parsing failure



It seems to me that Wireshark DTD parsing in /epan/dtd_parse.l doesn't take
into account that element and attribute names can validly contain a colon.
I think a possible fix would be to add a colon to:
name           [A-Za-z0-9][-a-zA-Z0-9_]*

--> 
name           [A-Za-z0-9][-a-zA-Z0-9_:]*


Regards and thanks,
Zivan
