Bug description: appendChild breaks loop when copying imported tree
Description:
------------
When a node tree is copied from one DOMDocument to another using
recursive importNode on the tree root and then copying the
childNodes in a loop (doesn't matter whether for or foreach) using
e.g. appendChild, the loop is no more repeated after copying the
first element, that means, other child elements do not get copied.
Additionally, the source childNodes->length gets decremented.
The opposite approach - iterating through the source elements and
importing&appending one at a time works flawlessly.
On commenting out the appendChild call the iteration goes normally,
too.
Reproduce code:
---------------
<?php
error_reporting(E_ALL | E_STRICT);
$srcdoc = new DOMDocument("1.0", "UTF-8");
$src = $srcdoc->appendChild($srcdoc->createElement("srcroot"));
$src->appendChild($srcdoc->createElement("elem1", "1"));
$src->appendChild($srcdoc->createElement("elem2", "2"));
echo $srcdoc->saveXML();
$dstdoc = new DOMDocument("1.0", "UTF-8");
$dst = $dstdoc->appendChild($dstdoc->createElement("dstroot"));
$tmp = $dstdoc->importNode($src, TRUE);
echo $tmp->childNodes->length;
foreach ($tmp->childNodes as $child) {
echo ".";
$dst->appendChild($child);
}
echo "\n";
echo $dstdoc->saveXML();
?>
Expected result:
----------------
The output should look like this (both elements copied):
<?xml version="1.0" encoding="UTF-8"?>
<srcroot><elem1>1</elem1><elem2>2</elem2></srcroot>
2..
<?xml version="1.0" encoding="UTF-8"?>
<dstroot><elem1>1</elem1><elem2>2</elem2></dstroot>
Actual result:
--------------
The output looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<srcroot><elem1>1</elem1><elem2>2</elem2></srcroot>
2.
<?xml version="1.0" encoding="UTF-8"?>
<dstroot><elem1>1</elem1></dstroot>
That means the elem2 did not get copied. There is also only one dot
at the "2." row, meaning the second iteration of the loop hasn't
even started.
