Summary: ChildNodes of DOMNodes list great childs, etc. as
DOMText
Status: Open
Type: Bug
Package: DOM XML related
Operating System: Debian Linux
PHP Version: 5.4.19
Block user comment: N
Private report: N
New Comment:
In your example the nodes B1 and B2 do not have text content. I cannot reproduce this bug:
php --version
PHP 5.5.16 (cli) (built: Aug 21 2014 14:25:20)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies
with Xdebug v2.2.5, Copyright (c) 2002-2014, by Derick Rethans
<?php
$xml = new DOMDocument();
$xml->loadXml('<R><A1><B1>B1</B1><B2>B2</B2></A1><A2/></R>');
foreach ($xml->documentElement->childNodes as $childnode) {
echo get_class($childnode) . "\n";
}
Gives:
DOMElement
DOMElement
Where is the bug in your first example?

Hi,
I'm not sure what information is missing from the bug description but here are more
explanations :
- an XML document is mainly a syntactical formulation of a rooted labeled tree structure.
- in a rooted tree structure, "A is the parent of B" means that A is adjacent (linked by
an edge) to B and A is on the path between B and the root of the tree (B may be the root of the
tree). If "A is the parent of B", "B is a child of A".
Let R be the label of the root, consider the following example:
R
/ \
A1 A2
/ \
B1 B2
Nodes with labels A1 and A2 are "children" of node with label R.
Nodes with labels B1 and B2 are "grandchildren" of node with label R.
This labeled tree can be represented by the following XML :
<R>
<A1>
<B1/>
<B2/>
</A1>
<A2/>
</R>
Assume R is a DOMNode,
expected content of childNodes of R :
A1, A2 as DOMElements
actual bugged content of childNodes of R :
A1 as DOMElement, text content of B1 as DOMText,
text content of B2 as DOMText, A2 as DOMElement
Best regards,
Laurent Lyaudet

My bad, it looks similar to bug 40175 but looking at the sample code for 40175 it is totally
different. 40175 use getElementsByTagName but the description says
The childNodes "function" returns a DOMNodeList (I added the quotes)
I mentally corrected to "The childNodes is a DOMNodeList" when I first looked at this
shit.

Description:
------------
Hi,
When using DOMNodes and other heriting classes (DOMDocument, DOMElement, etc.),
the childNodes attribute lists real childrens as DOMElement mixed with DOMText for the content of
grandchildren.
It is similar to bug 40175 but more detailed. Moreover I don't see why the manual is cited as a
justification for bug 40175:
from http://www.php.net/manual/en/class.domnode.php
:
> childNodes>> A DOMNodeList that contains all children of this node. If there are no >children, this is
> an empty DOMNodeList.
I join a debug function to supplement the bug in var_dump (see bug 65565 : https://bugs.php.net/bug.php?id=65565&thanks=4).
function debugSousBalises($p_oBalise){
for($i = 0; $i < $p_oBalise->childNodes->length; ++$i){
$oNode = $p_oBalise->childNodes->item($i);
//var_dump($oNode);
switch(get_class($oNode)){
case 'DOMText':
echo $oNode->wholeText;
break;
case 'DOMElement':
echo $oNode->tagName.' : '.$oNode->nodeValue;
break;
default:
echo get_class($oNode).' pas encore pris en compte';
}
}
}
used on the following fragment of xml
<balise>
<ata>2013-08-20T17:13:25</ata>
<atd>2013-08-20T17:15:03</atd>
<callSequence>1</callSequence>
<actualCallSequence>2</actualCallSequence>
<clauseInfo>
<clause>LIV_CFM</clause>
<description>Conforme</description>
</clauseInfo>
</balise>
it will yield:
ata : 2013-08-20T17:13:25
atd : 2013-08-20T17:15:03
callSequence : 1
actualCallSequence : 2
clauseInfo :
LIV_CFM
Conforme
