Re: Constructing complex xs:string in variable

Also let's not forget

<xsl:variable name="var" select="''prefix' || $somevar || 'part'"/>

(as long as we are on the topic)

I agree that the distinction between strings and text nodes is a fine one, but
useful and important to understand. It represents one of the boundaries
between the regimented world of the tree and the open world of XPath.

Cheers, Wendell

Yes - I'd probably write,
<xsl:variable name="var" as="xs:string"
  select="concat('prefix, 'part1', ....) "/>

In XSLT 3 you could also do,
<xsl:variable name="var"
as="xs:string">prefix{'part1'}....</xsl:variable>

Assuming some XSL ancestor has expand-text="yes"
