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

["Don Smith dsmith_lockesmith@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

 Thank you both, Liam and Wendell. After Liam's reference to the relevant part
of the spec I checked it and realized the <xsl:text> approach would work and
had my obligatory "D'oh!" moment. I think I'll use that as I find it more
legible.

 Hi,
You could also have:
B <xsl:variable name="generatedTextAfter" as="xs:string?"><xsl:text>
</xsl:text></xsl:variable>

The deal is that directly inside that xsl:variable, a whitespace-only text
node in the XSLT is considered to be 'cosmetic' and dropped. So there is no
space to be placed into the result.
Adding xsl:text forces the text node, which is then cast to a string following
theB @ as .
(What are those robots doing to my notation?)
Cheers, Wendell

I tried,
<xsl:variable name="generatedTextAfter" as="xs:string?" select=" ' '
"/>
and got output.


The relevant text in the spec is this:
