RE: [xsl] Greater than and Less than Booleans.

GOT IT!

This removes the dashes and allows the dates to be compared.

<xsl:if test="translate(D1DUE,'-','') &lt; translate(REVODUE,'-','')">

Thanks Michael

Thanks Ben, Brook, & Michael,

I removed the dashes from the numbered date/strings and the &gt; worked; I
guess I will have to figure out another way to display my dates in order to
use these Booleans.

Again Thanks.

Brook,
  There doesn't appear to be anything explicit about this in XSLT 1.0, but 
in XPath 1.0 it has the following paragraph under 3.4 Booleans:

"When neither object to be compared is a node-set and the operator is <=, <,

 >= or >, then the objects are compared by converting both objects to 
numbers and comparing the numbers according to IEEE 754. The < comparison 
will be true if and only if the first number is less than the second number.

The <= comparison will be true if and only if the first number is less than 
or equal to the second number. The > comparison will be true if and only if 
the first number is greater than the second number. The >= comparison will 
be true if and only if the first number is greater than or equal to the 
second number."

This seems to be exactly as Micheal Kay described it.  Hope that helps...
Benjamin
