Elements in the DOM contain an array of their children, where
"children" are element nodes, text nodes, and a few others.  Frex,
"<p>foo <i>bar</i> baz</p>" contains at least three nodes - a text
node containing "foo ", a i element node, and a text node containing "
bar".  It's possible, though, for those text nodes to be split into
multiple pieces - the first one could be a text node containing "f"
and another containing "oo ".

I'm not sure how difficult it would be to match across text nodes.  I
feel it's pretty necessary, though - runs of adjacent text nodes are
normally invisible to the user and author, and having things not match
at seemingly random times because, say, a hiccup in the network forced
the parser to pause and end the text node it was constructing, would
be a very bad thing.
