Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to

You have to use DOM there. All you were doing was replacing the item at
index 0 in the $nodes array with the string "World".

I've come up with a workaround which imports the SimpleXML obkect into
DOM and then converts back, but this, of course, defeats the purpose of
SimpleXML. For reference I will post it here for others who need a
solution to this problem:
$domnode = dom_import_simplexml($xml);
$dom = new DOMDocument();
$domnode = $dom->importNode($domnode, true);
$dom->appendChild($domnode);
$x = new DOMXPath($dom);
$n = $x->evaluate('/root/node');
while ($n->item(0)->firstChild) {
$n->item(0)->removeChild($n->firstChild);
}
$n->item(0)->appendChild($dom->createTextNode('World'));
$xml = simplexml_import_dom($dom);

Description:
------------
When trying to set the value (inside text) of a node from an array
returned from an xpath call nothing happens. Setting an attribute works
fine, however. Setting via normal -> access works as expected.
Reproduce code:
---------------
$xml = simplexml_load_string('<root><node/><node2/></root>');
if (is_array($nodes = $xml->xpath('node'))
&& sizeof($nodes) > 0
&& is_object($nodes[0])) {
$nodes[0]['value'] = 'Hello';
$nodes[0] = 'World';
}
$xml->node2 = 'World';
header('Content-Type: text/xml');
echo $xml->asXML();
Expected result:
----------------
<root><node
value="Hello">World</node><node2>World</node2></root>
Actual result:
--------------
<root><node value="Hello"/><node2>World</node2></root>
