Running PHP 4.2.1 with Apache 2.0.36 on Windows 2000 Profrofessional.  PHP is running as an Apache module.

XML extension enabled
XSLT extension enabled

For some reason when parsing documents that like:

<doc>
<para>Some text <test /> rest of para text</para>
</doc>

The CDATA that is returned through the xml_set_character_data_handler seems to return the rest of the para CDATA instead of nothing.

After the data handler has been called, then it calls the element handler to close the <test/> tag.

An easy way to test is to keep track of the current tag that the parser is on (by setting it in the open element handler) and then running strlen over the CDATA has it hits the test tag.

Logically it should close the tag, then process the CDATA or at least return blank CDATA for the test tag.
