RE: [xsl] Center string

["Michael Kay" <mike@xxxxxxxxxxxx>]

I think you need to move from

(0) a set of examples, to

(1) a requirement statement, to

(2) an algorithm, to

(3) an implementation in XSLT code.

Perhaps (1) is something like: generate the output in as few lines as
possible given the maximum line length, and then divide the words between
lines so as to minimize the maximum variation between actual line length and
average line length.

Perhaps (2) is something like:

  (a) compute the minimum number of lines by first trying to pack the words
as densely as possible.

  (b) compute the average line length by dividing the total length by the
minimum number of lines

  (c) flow the words into lines breaking each line at the closest possible
point to the average line length.

If that's OK, then step (3) is relatively straightforward so long as you are
comfortable with recursion, though like most such things it's likely to be
much easier in XSLT 2.0 than in 1.0.
