<a>
<b attr="w1 w3 w6">...</b>
<b attr="w2 w12 w3 w7">...</b>
... more <b>s here ...
</a>
when processing an <a> element, i need to calculate the
maximum number of whitespace-separated words for any
"b/@attr" attribute. so just what you see above, the value
would be 4, based on that second <b> child of <a>.
AFAICT, this will involve three steps:
1) collect the "b/@attr" attributes (easy)
2) normalize space and word count each of those attribute values
(again, easy, stealing from kay, p. 527, the "word-count"
template :-)
3) finding the maximum of those values
You can count the words without recursive processing:
$x := normalize-space(@attr)
$y := translate(@attr, ' ', '')
$wc := string-length($x) - string-length($y) +1
since, as i understand it, you can't have a node-set of just
numbers,
Since numbers aren't nodes, how could you have a node-set containing
numbers?
In XPath 2.0 of course you can have sequences of strings or numbers
which makes this kind of thing very much easier.
