That's iterating over the .attributes collection checking the namespace-
URI fields of the Attr nodes in the process. Trivial in a conforming im-
plementation.

I don't understand this requirement. What should it do for

  <foo xmlns:bar="x">
    <foo xmlns:bar"y">
      <foo bar:baz="..." xmlns:x="x" x:z='...'/>
    </foo>
  </foo>
