xsl when boolean expression
Ed,

If I understand you correctly, what you want is as simple as

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:variable name="claim" select="1 > 2"/>

<xsl:template match="/">
  <xsl:choose>
    <xsl:when test="$claim">True</xsl:when>
    <xsl:otherwise>False</xsl:otherwise>
  </xsl:choose>
</xsl:template>

</xsl:stylesheet>

I tested this by running it against itself in Saxon, and it works as expected.

I hope that helps,
Wendell

I have state information I need/wish to capture in a
"boolean" variable.   I need to use the result of the expression in
multiple places; I do not wish to replicate the expression everywhere it
is needed for maintenance reasons.  The value is "static" and I can
establish it at a global context.

I have yet to figure out how to do it.  No matter what I try I get a
position evalution of the variable.  I can print the variable and see
that I am getting the correct boolean value (true or false).    How do
I capture the results of a boolean expression in a variable and how can
I then test the value of that variable?


Please don't ask for details; I don't want specific point-source alternatives for how to work around the issue I want to how to capture the results of a boolean expression and then use those results later in a conditional expression (e.g. xsl:if or xsl:when).

Thanks,
Ed Knoll
