Re: [xsl] Collect all the truncated fields in an array

[David Mitchell <david.mitchell@xxxxxxxxx>]

Sure.

You need to stop thinking of storing away the results of your
computations as you go.

Instead, think of processing the input twice.

Once to create the structure you have so far (but truncate the values
as you go).

Then, process the input again and create the <TruncatedValues> element
and its content.

You need to read up on template modes.

If you are having these sorts of problems, you may want to invest in a
good book. XSLT Quickly is short and to the point. Any of Jeni
Tennison's books would be excellent.
