Bug description: xml_parse / xml_set_character_data_handler doesn't resolve
simple entities
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
