[xsl] attribute length

["Russ Little" <russ.little@xxxxxxxxxxxx>]

I am attempting to use logic to determine the length of an attribute, but I'm
unable to find anything useful enough to work.

If I have the following:

<CAT NAM="This attribute is meant to be so extremely long that I must force it
into multiple cells on a web page"/>

What I want to do is take the NAM attribute, and put the first 35 characters
into a cell.  Directly below it, I want to generate another cell with two
spaces followed by the next 33 characters.  I want to generate a new cell
directly below the previous one, every 33 characters after the initial 35, and
each should have two spaces in front.  This basic logic would produce the
following:

This attribute is meant to be so ex
  tremely long that I must force it
  into multiple cells on a web page


The tricky part is, once I count to 35 characters (or 33 depending on if it is
the first cell or not), I need to verify the data is being separated at a
space.  In the previous example, the word "extremely" is not separated
smoothly.  The final result should actually be:

This attribute is meant to be so
  extremely long that I must force
  it into multiple cells on a web
  page

How can I use logic to not only determine the length of the attribute, but
depending upon that length, separate the data out into multiple cells on a web
page?
