PHP Bug Type: SimpleXML related
Bug description: addChild() on a non-existent node, no node created, getName()
segfaults
Description:
------------
addChild() does not behave as expected(?) when used on a node that wasn't
previously declared.
In the example below, we initialize an empty tree, to which we attempt to
add a new node at "/child/grandchild" without previously adding "child" to
the tree. addChild() seems to operate on a temporary SimpleXMLElement and
the changes are never applied to the original object/tree.
I believe that this bug is also responsible of the segfault that happens
if getName() is used on the temporary SimpleXMLElement. I was very tempted
to file this bug as a reproducible crash, but decided to file it under
SimpleXML in case it would help routing it to the maintainer faster.
Tested on:
PHP 5.2.4-dev (cli) (built: Jun 27 2007 20:04:30)
WinXP
libxml2 2.6.26
SimpleXML Revision: 1.151.2.22.2.29
PHP 5.2.2-pl1-gentoo (cli) (built: May 24 2007 00:26:35)
libxml 2.6.27
SimpleXML Revision: 1.151.2.22.2.26
Reproduce code:
---------------
<?php
$xml = simplexml_load_string('<?xml version="1.0" encoding="utf-8" ?><root
/>');
$xml->child->addChild('grandchild');
echo $xml->asXML();
Expected result:
----------------
I expect SimpleXML to create "child" if it does not exist, then add
"grandchild" to that node. The output should be:
<?xml version="1.0" encoding="utf-8"?>
<root><child><grandchild/></child></root>
Actual result:
--------------
Neither node is added to the tree. The output is:
<?xml version="1.0" encoding="utf-8"?>
<root/>
