Re: Re: Capturing/testing results of a boolean express

Maybe details are called for, because as I gnaw at this problem and read
archives I realize the trick might be to establish an expression which
returns a "boolean" as opposed to an expression which returns a
"results-tree-fragment".

I have a variable which will have a string value.  I wish to compare
that string value to another string value (which happens to be a literal
value).  I've done this directly in a xsl:if or xsl:when before, but now
I'm trying to capture the results of the expression in a variable.

<xsl:variable name="X" ..../>

<xsl:variable name="flag" select="$X = 'literal-string-value'" />

Is there a way to do this that returns a 'boolean' and not a
'results-tree-fragment'?

<xsl:variable name="flag">
  <xsl:value-of select="$X = 'literal-string-value'" />
</xsl:variable>

Is there a way to take a 'results-tree-fragment' which has the value
"true" or "false" and turn it back into the equivalent 'boolean' value?

Cheers,
Wendell
