Re: [xsl] match and not match using If

["Eliot Kimber ekimber@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

One issue is probably this line:

>  <xsl:variable name="aN" select="no"/>
> 
You probably expect the variable $aN to have the value "no" but you are
selecting an element named "no" as a child of the current context, which is
very likely not present, so the value will be an empty sequence.

So you probably want:

>  <xsl:variable name="aN" select="'no'"/>
For this kind of issue I like to use messages to check what's going on an in
particular verify my assumptions, e.g.:

<xsl:message> + [DEBUG] $an="<xsl:value-of select="$aN"/>"</xsl:message>

("+ [DEBUG] "is just my convention for formatting messages).

This is also a case where using @as would have revealed your error:

>  <xsl:variable name="aN" select="no" as="xs:string"/>
This will produce a runtime error if there is no <no> element because an
empty string is not a valid value.

Cheers,

Eliot
