xsl boolean() function and True/False

[sonnysavage]

I'm parsing some xml using xsl. I have some xml elements which are given the values of True and False. I want to use those values for a boolean test, but the boolean() function returns true for both of them (it tests whether string length is greater than zero).

Does anyone know of a quick way to convert True and False text strings to one or zero?

Make sure you use the new xsl namespace.
<xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;

http://www.w3.org/1999/XSL/Transform&quot;>

<xsl:value-of select=&quot;boolean('hello')&quot;/>
- this should evaluate to true
<xsl:value-of select=&quot;boolean('')&quot;/>
- this should evaluate to false

The <xsl:stylesheet xmlns:xsl=&quot;

working draft is completely different and things like boolean might not work properly.

But that's exactly my problem, the boolean() function evaluates length for strings. The functionality that I was looking for was this:

boolean("false") = FALSE
boolean("true") = TRUE

Both cases, however, evaluate to true. I ended up storing 1 for true and 0 for false in the XML, and I evaluated it this way:

boolean(number("1")) = TRUE
boolean(number("0")) = FALSE
