	The normalize() method on an Element node consolidates the
subtree so there are no adjacent Text nodes, merging Text nodes that
are next to each other into a single node.  So you could do
document.rootElement.normalize(), and then rely on the string being
contained within one node.  That won't catch tricky cases -- do you
need to find it if an entity expands to the string, or to part of the
string?  if the string had a PI in the middle of it, would it still
count as a match? -- but it'll certainly help with the simple case.

It is not that I wanted to know a great deal, in order to acquire what is now
called expertise, and which enables one to become an expert-tease to people
who don't know as much as you do about the tiny corner you have made your own.
