how to get the first sentence of an xml value?

hi everyone,

I'm looking for a solution for how to get the first sentence (ending with a
'.') of an xml value?
e.g.: xml looks like this:

    <para>Some text. And so on, the other sentences</para>

And I'd like to reference somehow to 'Some text.'.

Can XSL or XPath position for that text inline?

Any answers or solutions are welcomed.

Thanks.

Thomas
