XML-DOM slow?

[Mordy Ovits]

I've been playing around with the XML libraries, to great effect.  I
can't believe how useful it is.   However, it seems to be very slow. 
The (short) program at the bottom of this email takes about 10 seconds
to run!
What am I doing wrong?  Am I defaulting to a slow parser?
Thanks!

anchors = doc.getElementsByTagName('A')
for a in anchors:
    if a._node.attributes.has_key("HREF"):
        href = a._node.attributes["HREF"]
        print "Title: ", a._node.children[0].value
        print "Link: ", href.children[0].value
        print
    else:
        print "error in <A> (?)"
        print a._node.attributes
