Re: [xsl] Can I diplay the <expression> used by xsl:if test="<expression>"?

[René de Vries <RdVries at PCL-HaGe dot nl>]

Hi David,

I want to display the LITERAL text of the test.
So if it would be <xsl:if test="aNode &gt; 0"/> I want to display "aNode
&gt; 0".
Reason is that I want to pass the expression to a template to have it tested
and want to display in the template WHAT I've tested.

Something like this:
<xsl:call-template name="TestTheExpression">
    <xsl:with-param name="TheExpression" select="'aNode &gt; 0'"/>
</xsl:call-template>

<xsl:template name="TestTheExpression">
    <xsl:param name="TheExpression"/>

    <xsl:if test="$TheExpression"> // this won't work, because TheExpression
is now a literal and will evaluate to true....
        ... do something ..
        <xsl:value-of select="$TheExpression"/>
    </xsl:if>
</xsl:template>

Greetings René

don't use xsl:value-of just use
<xsl:text>test something</xsl:text>

Or use xsl:value of and use '...' so it's a string.
