Re: [xml-dev] How to handle "newline" characters in an XML parser.

["Redefined Horizons" <redefined.horizons@gmail.com>]

I should have clarified some things. :]

My parser is actually for a subset of XML, with no attributes,
comments, or CDATA. I looked at existing XML pull-parsers, but didn't
find one that made use of an event broadcasting mechanism like I
wanted.

The only reason I'm interested in counting lines is for the error
reporting. After reading the messages I think I've got more of a Java
problem than an XML problem. It really doesn't matter what the XML
Specs say in this particular case. What I need to figure out is how to
count the lines in text files created in different operating systems.

I do appreciate everyones help and suggestions.

P.S. - When I get the functional code for my parser online I'll post a
message to this list. Most won't be interested in the parser design,
but a few might be. :]
