Subject: RE: [xsl] Can I use a boolean variable in an xsl:if test From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Tue, 8 Feb 2005 15:58:35 -0000 |
This: <xsl:variable name="show"> <xsl:value-of select = "$time != 60000" /> </xsl:variable> is not a boolean variable, it is a result tree fragment. If you convert a result tree fragment to a boolean, the result is always true. The correct way to write a boolean variable is: <xsl:variable name="show" select="$time != 60000" /> I simply have no idea why this verbose, inefficient, and often incorrect style using <xsl:value-of> within <xsl:variable> has become so popular.
