new DomElement and Ampersand(&) in string

Hi,

I'm trying the following code (ultimately I want a node with a URI like
index.php?foo=1&bar)

<?php

$foo = new DomElement('foo','foo&bar');

?>

and get the following error message

ERRNO: 2
TEXT: unterminated entity reference bar
LOCATION: /users/peter/store/index.php, line 3, at July 16, 2005, 9:35
am
Showing backtrace:
DOMElement.__construct("foo", "foo&bar") # line 3, file:
/users/peter/store/index.php

I cannot find a way to escape the ampersand so that the DomElement
constructor will take it as a character. I tried &amp; which is no
different, I tried \& which is no different.

Thanks,
Peter
