First thing: I've fixed a bug related to this (%% did not match direct
successor) so please pull from the repository before trying the
following.

To match an element only if a sibling matches a subpattern, the right
syntax is:

  $ xmlgrep -x '{title%%category[@term=NetBSD]}' atom.xml

For example, consider the file:

  <a a="a" b="b">
    <b a="a">
      <d>Foo</d>
      <t>Bar</t>
    </b>
    <c b="b" />
  </a>

And the command:

  $ xmlgrep -x '{b%%c[@b=b]}#' test.xml
  <b a="a">
    <d>Foo</d>
    <t>Bar</t>
  </b>

I hope this helps.

As for a case-insensitive mode, there is none at the moment, but it
could be added easily.
