[xsl] "Convert" true/false to 0/1

["Aron Bock" <aronbock@xxxxxxxxxxx>]

Hello, I'm using ... xalan I think (actually the ant xslt task, which I 
think uses xalan) ... to process an XML document wich contains some attrs 
with the value "false".  I want the output document to output a "0" for 
false, 1 for true; in cases where the attr holding true/false is missing, 
assume true.

The input XML looks like this:

<data>
    <foo name="apple" edible="false"/>
    <foo name="banana"/>
</data>

I want the output document to look like this:

<data>
   <foo name="apple" edible="0"/>
   <foo name="banana" edible="1"/>
</data>

edible is defined in an assocuiated XML schema as xs:boolean

At some point in the transform I thought the following would work (assume 
$foo refers to a <foo>):

<xsl:choose>
 <xsl:when test="$foo/@edible and $foo/@edible = false">0</xsl:when>
 <xsl:otherwise>1</xsl:otherwise>
</xsl:choose>

But apparently not.  Would somebody suggest a compact way of achieving the 
above, again asuming $foo.

Thanx
