SAX Parser and CDATA
Hi all,
I have xml file and I use SAX parser to parse it. Why is SAX parser parsing
content of CDATA section? I am using default configuration of SAX parser.
All I need to do is to get content of CDATA section and dump it to the file,
all this using SAX parser. Any suggestions? Thanks

Hi Tomas,
There seem to be articles floating around the net which claim that CDATA
sections are 'ignored' by XML parsers. One such article is at:
http://www.w3schools.com/xml/xml_cdata.asp. It contains quite a bit of
erroneous information, including the claim that CDATA sections are
ignored. CDATA sections are parsed. They are not ignored (or skipped).
CDATA sections are identical to regular character data, except that you're
allowed to include '<' and '&' in these sections without having to escape
them. In fact you cannot escape any characters in CDATA.
If you've registered a ContentHandler with the parser, the content of the
CDATA section will be reported in the characters callback. You'll have to
buffer the text yourself, as the parser is free to split the section into
multiple callbacks for performance reasons.
Hope that helps.
