Salathe, thanks for the point, you are right.
Replacing the xquery by '//text()[contains(., "world")]/..' works perfectly.

I may be wrong, but my understanding is as follows.
text() returns a list of node [1], whereas contains() expects two string
arguments [2]. Because of this the list of
text nodes is converted to a string, as with string():
"A node-set is converted to a string by returning the string-value of the node
in the node-set that is first in
document order. If the node-set is empty, an empty string is returned." [3]

Description:
------------
When a node has inner nodes and you want to search into its text value, only
the first text node is selected.
This is wrong because, as http://www.w3.org/TR/xpath/#path-abbrev says:
> text() selects all text node children of the context node
Test script:
---------------
$xml = <<<END
<?xml version="1.0" encoding="UTF-8"?>
<root>
<first>
Hello
<second>
world
</second>
world
</first>
</root>
END;
$doc = DOMDocument::loadXML($xml);
$xpath = new DOMXPath($doc);
foreach ($xpath->query('//*[contains(text(), "world")]') as $node)
echo $node->nodeName . PHP_EOL;
Expected result:
----------------
first
second
Actual result:
--------------
second
