I give you libxml:

    xmllint --xpath '//element/@attribute'

There's a good chance it's already installed on your mac.

To avoid the hassle of handling xml namespaces (e.g. in an Atom feed...), just do:

    xmllint --xpath '//*[local-name()="element"]/@attribute'

Note: for consistency, namespaces are not needed for attribute names.
