I understand the suggestion to use a recursive template to filter
the output. The problem I was having was that the sentences can
contain the <span> tags. It seems to me that the fragments that
are being processed are sometimes text and sometimes the child
tags. I guess I'm confused how the pieces an element are processed
when it has tags mixed with text.

Your are right it would normally be difficult but the content is technical
and doesn't usually contain other types of punctuation such as ? and !. I
was thinking of using '. ' as the delimiter. If I happen to get an extra
sentence because of other punctuation it is not a problem. This template is
being used to create a short summary of a piece of a doecument. Also, the
<span> tags don't cross sentence boundaries so that huge mess is avoided.

I guess another possibility it to output n characters and add '...' at the
end to create the summary. Is that any easier?

Thanks for your help,
Jim
