Ok,I changed the I-can't-overload methods to getAttributeValueFromName
and getNamespaceFromPrefix.

Well, you know you have to rely on the language you use, along as the
API is respected there will be some behavioural changes due to the
nature of the language, in PHP instead of exceptions I throw PHP
warnings, the user can intercept them if he wants. In PHP5 there will
be exceptions and I'll change this class as well as several others in
order to use exceptions, a much nicer error handling mechanism.

I'll have some gamma version of the parser soon (Monday I guess) so
I'll send it to you and check if it is ok as a XML-PULL implementation.

Do you have an email address to send me for files and so?
