Summary: CharacterDataHandler ampersand problem

Initial Comment:
If you parse <tagname>A&amp;B</tagname>, the characterdatahandler is called 3 times, each with the nodename of tagname, first with A, then with &, then with B

It's absolutely normal parser behaviour. Extraction from expat
documentation: "...A single block of contiguous text free of markup may
still result in a sequence of calls to this handler. In other words, if
you're searching for a pattern in the text, it may be split across calls to
this handler...". Please refer to the documentation in the future before
submitting any bug.

Expat is decoding entities on the fly so &amp; is exptected to give "&" in
the char data handler. In case that was not clear already.

This is legal behaviour. You can have multiple call-backs for a contiguous
text string.
This also (if I remember correctly) happens for line breaks.
