[oXygen-user] an xslt challenge

[James Cummings]

Hi Lou,

Would it make sense to use xsl:for-each-group to group the sentences into
<s> units to make this easier? Then I'd probably recursively call a
template or function passing the current collection of <s> units as a
variable item* value, testing if its tokenised number is above or below
$maxWords.

Not got time to write that out as a solution atm, and I'm sure it can be
done without the recursivity as well, but that is the approach that would
have occurred to me at least.
