New Comment:
Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.

Description:
------------
It may be a misunderstanding of mine, but xml_parse doesn't seem to
resolve 'simple' entities like < > or &. According to the doc,
and one other bug report, I think it should.
While other parsers (XMLReader, SimpleXML, DOM, ...) do.
In numerical form, it does work (>).
I tested with libxml2 versions 2.7.1 and 2.7.2, and expat 2.0.1.
I found this when doing SOAP calls, I couldn't pass the value "<" to a
PHP SOAP server (which is using NuSOAP).
I don't have a workaround for the moment.
Reproduce code:
---------------
function character_data($parser, $data){
print("character_data: $data\n");
}
function parsestring( $strg ) {
$parser = xml_parser_create("UTF-8");
xml_set_character_data_handler($parser,'character_data');
xml_parse($parser,$strg,true);
xml_parser_free($parser);
$reader = new XMLReader();
$reader->XML( $strg );
while( $reader->read() ) {
if( $reader->value ) print( $reader->name . ": " .
$reader->value . "\n");
}
}
$xmlcdata = "<element><![CDATA[A>B&C<D]]></element>";
$xmlescaped = "<element>A>B&C<D</element>";
$xmlnumeric = "<element>A>B&C<D</element>";
print("parsing $xmlcdata \n");
parsestring( $xmlcdata );
print("\nparsing $xmlescaped \n");
parsestring( $xmlescaped );
print("\nparsing $xmlnumeric \n");
parsestring( $xmlnumeric );
Expected result:
----------------
parsing <element><![CDATA[A>B&C<D]]></element>
character_data: A>B&C<D
#cdata-section: A>B&C<D
parsing <element>A>B&C<D</element>
character_data: A
character_data: >
character_data: B
character_data: &
character_data: C
character_data: <
character_data: D
#text: A>B&C<D
parsing <element>A>B&C<D</element>
character_data: A
character_data: >
character_data: B
character_data: &
character_data: C
character_data: <
character_data: D
#text: A>B&C<D
Actual result:
--------------
parsing <element><![CDATA[A>B&C<D]]></element>
character_data: A>B&C<D
#cdata-section: A>B&C<D
parsing <element>A>B&C<D</element>
character_data: A
character_data: B
character_data: C
character_data: D
#text: A>B&C<D
parsing <element>A>B&C<D</element>
character_data: A
character_data: >
character_data: B
character_data: &
character_data: C
character_data: <
character_data: D
#text: A>B&C<D
