PHP Bug Type: DOM XML related
Bug description: DOMCharacterData extending bug
Description:
------------
In my example code class RawStuff extends DOMCharacterData and creates a
fetch error, which I can't see why it's happening (nothing in the PHP
manual or DOM specs seems to say anything as far as I can see).
If I change the code to
class RawStuff extends DOMText
then the code doesn't error, however I don't want it to escape the < and >
characters, which is why I want to extend from DOMCharacterData as this
shouldn't escape < and > (coz it doesn't in DOMComment and that extends
DOMCharacterData).
As far as I can see this seems to be a bug though, there maybe some good
reason why this doesn't work, however there seems to be no mentioning of
it in both the DOM Spec of PHP manual.
Reproduce code:
---------------
<?php
header('Content-type: text/plain');
class RawStuff extends DOMCharacterData {
public $poop;
}
class NiceElement extends DOMElement {
}
$o = new DOMDocument();
// Expecting <scum /> to be escaped here with > and <
$p = new NiceElement('html', ' ppp<scum /> pp', '12121212');
$o->appendChild($p);
// Not expecting <% and %> to be escaped as DOMComment extends the
DOMCharacterData class
// and this allows things like <!-- <scum /> --> without turning < and >
into entites
// However we can't use DOMCharacterData directly without a fetch error
for some reason
$cack = &new RawStuff('blah some node which can also hold raw <% asp data
%>');
$p->appendChild($cack);
$cack2 = $o->createTextNode('fgfgf');
$p->appendChild($cack2);
echo $o->saveXML();
?>
Expected result:
----------------
<?xml version="1.0"?>
<html xmlns="12121212"> ppp<scum /> ppblah some node which can also
hold raw <% asp data %>fgfgf</html>
Actual result:
--------------
<br />
<b>Warning</b>: Couldn't fetch RawStuff in
<b>/data/web/test_stuff/DOM_test.php</b> on line <b>22</b><br />
<?xml version="1.0"?>
<html xmlns="12121212"> ppp<scum /> ppfgfgf</html>
