[xsl] Comparing element values

["Kevin Bird" <kevin.bird@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi

Within the following structure I need to compare the value of two
<price> elements and output the one with the highest value only. In the
example below, the 3rd and 4th <price> elements are being compared.

Any help would be greatly appreciated.

PS: At a later date I would like to be able to compare a range of
<price> elements. Better learn to walk first!
