RE: [xsl] expression syntax

[George James <GeorgeJ@xxxxxxxxxxxxxxx>]

You could use the translate function to strip out the hyphens and make the
dates into integers that can then be compared numerically.

  <xsl:variable name="iToday" select='translate($today,"-","")'/>
  <xsl:for-each select='performance[translate(@date,"-","") &gt;=
$iToday]'/>

But note that this is not appropriate for dates earlier than 1CE (because
these are represented as -yyyy-mm-dd).

Xpath 2.0 appears to be introduce the capability to cast a string as a date
and operator mapping so that you can perform a comparison between two dates
directly.
