(define (test-sxml port)
(let ((x (xml->sxml port)))
((sxpath '(// p @ foo)) x)))
(call-with-input-file "test.xml" test-sxml)
(test-sxml) will return a list like this:
((foo "x") (foo "y") (foo "z"))
Or, if you use (sxpath '(// p)) you will get all full <p>:
((p (@ (foo "x")) "hello ") (p (@ (foo "y")) "hello 2 ") (p (@ (foo
"z")) "hello 3"))
Hope this helps,

I've tried it with:
<?xml version="1.0" encoding="UTF-8"?>
<body>
<div>
<p foo="x">hello </p>
<p foo="y">hello 2 </p>
<p foo="z">hello 3</p>
</div>
</body>
