Hi,
Thanks for the feedback and showing me that the bug was because of incorrect node value and not
because of additionnal DOMText elements.
I opened another bug report for correcting node value instead, as you suggested.
Best regards,
Laurent Lyaudet

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
A slight modification of your first test script (see
<http://3v4l.org/VmfC7>) shows that the grand-children are
not
iterated over. "LIV_CFM" and "Conforme" are yield by ::nodeValue
(what may be considered a bug, but that should be reported in a
separate ticket).
The results of the second test script also do not contain
grand-children; there are 5 children and these are printed as
DOMElement, while the TextNodes are built from the whitespace
between the elements. Simply strip all whitespace, and you get the
desired result (see <http://3v4l.org/YsTE8>).

Hi,
the bug appears with this test script :
<?php
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';
}
}
}
$xml = new DOMDocument();
$xml->loadXml('<balise>
<ata>2013-08-20T17:13:25</ata>
<atd>2013-08-20T17:15:03</atd>
<callSequence>1</callSequence>
<actualCallSequence>2</actualCallSequence>
<clauseInfo>
<clause>LIV_CFM</clause>
<description>Conforme</description>
</clauseInfo>
</balise>');
debugSousBalises($xml->documentElement);
?>
It gives
ata : 2013-08-20T17:13:25
atd : 2013-08-20T17:15:03
callSequence : 1
actualCallSequence : 2
clauseInfo :
LIV_CFM
Conforme
as explained.
If you don't use my debug function but use your loop with echo, the following test script
yields also something buggy :
<?php
$xml = new DOMDocument();
$xml->loadXml('<balise>
<ata>2013-08-20T17:13:25</ata>
<atd>2013-08-20T17:15:03</atd>
<callSequence>1</callSequence>
<actualCallSequence>2</actualCallSequence>
<clauseInfo>
<clause>LIV_CFM</clause>
<description>Conforme</description>
</clauseInfo>
</balise>');
foreach ($xml->documentElement->childNodes as $childnode) {
echo get_class($childnode) . "\n";
}
?>
yields
DOMText
DOMElement
DOMText
DOMElement
DOMText
DOMElement
DOMText
DOMElement
DOMText
DOMElement
DOMText

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
