If i get myself a DOM tree using xml.dom.minidom (or full-fat xml.dom,
i
don't mind)
"""
Don't do that. Stick to minidom. The "full" xml.dom from PyXML is
ancient and slow. Of course, there are other, better libraries
available now, too.

is there an easy way to ask a element for its child elements
of a particular type? By 'type' i mean 'having a certain tag'.
"""
You can use list comprehensions[1]. You could use XPath, if you're
willing to use a library that supports XPath.
In Amara[2], this task is trivial. To get all the images in an XHTML
div, you'd simply do:
for img in div.img:
process_img(img)
You access names directly as objects according to their element type
name.
