Hi Dan,

>  I have a document made up from a collection of addresses like this:

You can select all the contacts whose name contains 'Corneanu' with:

  /address-book/contact[contains(name, 'Corneanu')]

As you no doubt know, though, contains() is a case-sensitive function.
You make it case-insensitive by converting the name (and the string
that you're testing with) to lowercase, which you can do with the
translate() function, as follows:

  /address-book/contact
    [contains(translate(name, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
                              'abcdefghijklmnopqrstuvwxyz'), 'corneanu')]

If you only test for 'Corneanu', you may as well just convert those
letters:

  /address-book/contact
    [contains(translate(name, 'CORNEAU',
                              'corneau'), 'corneanu')]

Cheers,

Jeni
