RE: [xsl] Peculiar Problem in .xsl file

["Michael Kay" <michael.h.kay@xxxxxxxxxxxx>]

I think your code is correct and your processor is buggy. Which XSLT
processor are you using?

When a string is compared to a number, they should be compared as
numbers, not as strings.

Try doing 
<xsl:variable name='month' select='number(substring ($date, 5, 2))'/>

to force a numeric comparison.

[Note, this kind of problem is one of the reasons that many people are
so keen to add stronger typing to the language].
