Yep, that looks like a bug... Can you please file a bug at bugs.php.net?
The workaround is the write the following:
$node = $dom->createElement("foo");
$text = $dom->createTextNode( "which entities does it
escape & which doesn't it?");
$node->appendChild($text);
$root->appendChild($node);
While a little more to type, it's at least the official W3C way ;)

Thanks, both Jason and Christian
I found something else that I think is strange.
$dom = new DOMDocument();
$root = $dom->createElement("test");
$dom->appendChild($root);
$node = $dom->createElement("foo", "which entities does it
escape & which doesn't it?");
$root->appendChild($node);
echo $dom->saveXML();
The result will be:
which entities does it escape
It stops at the &, which I think is strange. It escapes the < to <
and > to >, but not & to &. It would be better if it escaped none
or all entites that "can do harm".
Or what do you think?

Victor

Re: [PHP] PHP5, XPath and count()
this doesn't work yet in DOM. The returned value has to be a nodeset. Will be fixed some day ;) see victors answer for the work around chregu I was wondering about that. So is there someplace online where we can find out what does / does not yet work for XPath? I've been looking but google only gives about 9 hits for DomXPath. If I wasn't such a lousy C coder I'd try to go trudging through the source myself :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

this doesn't work yet in DOM. The returned value has to be a nodeset.
Will be fixed some day ;)

[PHP] PHP5, XPath and count()
Assume an XML file that looks like:
..
..
..
... and that I would like to know the number of CDs. An xpath expression
would look like count(/catalog/cd), but how do I run this expression?
$dom = new DOMDocument();
$dom->load("catalog.xml");
$xpath = new DOMXpath($dom);
var_dump($xpath->query("count(/catalog/cd")->item(0));
... returns NULL.
Any ideas?
Thanks in advance,
Victor
