First: your example XML is broken. (Unescaped angle brackets in
content.)

Next: microparsing, and of text content no less (as opposed to
attribute values)? How hideous.

I will suggest something like

    <audience rel="to"
        address="acct:john.doe@example.org"
        label="acct:john.doe@example.org" />

The label should be optional of course.

Now you have something tractable to XML tools, eg. you can write
reasonable XPath queries across these elements.
