Bug #31139 "XML Parser Functions" seem to drop & when parsing
Submitted: 2004-12-16 23:06 UTC Modified: 2004-12-17 13:22 UTC
From: exaton at free dot fr Assigned:
Status: Closed Package: XML related
PHP Version: 5.0.3 OS: Windows XP
Private report: No CVE-ID:

Description:
------------
I parse my XML with the "XML parser functions" (xml_parser_create() and all that). Up to PHP 5.0.2 I had no problem, and suddenly the following has appeared in 5.0.3 :

I used to put é in an XML file to recuperate the é HTML entity in my page output and therefore an acute-accentuated e in the text. This was perfectly coherent with XML specs, and worked fine.

Now the output on the page has simply dropped the "&" that should come from & , therefore parsing é into eacute; -- which of course is perfectly unwanted.

é is of course not the only affected entity : I'm not seeing a single & in any content obtained from parsing XML.

Note : explicitely passing a charset string to xml_parser_create() did not solve this.

Reproduce code:
---------------
$this -> parser = xml_parser_create();

xml_parser_set_option($this -> parser, XML_OPTION_SKIP_WHITE, 1); 
xml_parser_set_option($this -> parser, XML_OPTION_CASE_FOLDING, 0);

// $this -> contents has the plaintext contents of an XML file, prone to contain things like é

xml_parse_into_struct($this -> parser, $this -> contents, $this -> values, $this -> index);

xml_parser_free($this -> parser);

Expected result:
----------------
When I eventually recuperate the output with my custom architecture, I expect things like é to have been parsed into é -- they always were up to and including PHP 5.0.2 .

Actual result:
--------------
In PHP 5.0.3, é for example is now parsed into eacute;
