Re: [xsl] Outputting White Space Only Nodes from Variables

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi again,

White space ...

<xsl:variable name="generatedTextAfter" as="xs:string"
xml:space="preserve"> </xsl:variable>

Not exactly sure what advantage it gives here, but this is handy to be able
to do. (I wouldn't use it for a space, but I might use it for a chunk of
CSS.)

Cheers, Wendell
