Operating system: Windows 2000 / SP4
PHP version: 4.3.4
PHP Bug Type: DOM XML related
Bug description: get_elements_by_tag_name() wildcard fails
Description:
------------
The use of a wildcard with the get_elements_by_tagname() method to obtain
a collection of all DomElement nodes in a document appears to be broken in
PHP4.3.4 for Windows. Rather than returning an array, it returns NULL.
Upgrading broke numerous scripts depending on this behaviour, which
reverted to normal as soon as I rolled back to 4.3.3.
The use of "*" as a wildcard in this fashion is per the W3C DOM spec, and
performed as expected in PHP4.3.0-4.3.3 / win32.
Extensions enabled: cpdf, ctype, curl, domxml, gd2, iconv, ming, pdf,
pgsql, xslt, yaz, zip
Versions of libxml, libxslt, and iconv used were those supplied in the
distributions downloaded from php.net.
Server: IIS/5.0
The only other apps installed on this system are: MySQL 4.1-alpha,
ActivePython-2.2.2-224, ActivePerl-5.8.1.807, MSIE 5.0, MSXML 4.0
Reproduce code:
---------------
<?php
// Used 2 small XML files which are known
// to be well-formed; domxml_open_file() succeeds
// in both cases
if( !$map = domxml_open_file( realpath("xml/map.xml") ) )
return;
$alltags = $map->get_elements_by_tagname("*");
echo count($alltags) . "<br>";
echo (is_array($alltags) ? "ARRAY" : "NOT ARRAY") . "<br>";
echo $alltags === NULL ? "NULL" : "NOT NULL";
?>
Expected result:
----------------
Script output under PHP 4.3.3:
138
ARRAY
NOT NULL
69
ARRAY
NOT NULL
The XML files used contain 138 and 69 tags each (counting the document
root), so these are correct. Both files were generated using DOMXML
DomDocument->dump_file(real_path("path/to/file.xml"), FALSE, FALSE).
Actual result:
--------------
Same script and XML files under PHP 4.3.4:
0
NOT ARRAY
NULL
0
NOT ARRAY
NULL
