and what about that ?
<xsl:value-of separator="|" select="$concat[string-length(.) gt 0]"/>

I am kindly asking for help with the following problem. It looks like a
FAQ, but I couldn't find it in Dave Pawson's XSLT 2 FAQ section.
I am declaring 3 variables named a, b, c which must receive their values
not from the "select" attribute of xsl:variable, but from its element
contents which contain each zero, one or more instances of xsl:text,
xsl:value-of or xsl:sequence. All 3 variables are meant to convey
strings only - but I suppose, as a consequence of the way they are
declared, they actually carry text nodes.
Which is the easiest way to join these 3 values into the value of a new
variable named result (just a string), given that only those values
which evaluate to non-empty strings should be separated by "|"?
Do I need explicit testing on each value for the empty string or can I
use a more concise technique?
but this does never insert a separator. Replacing xsl:value-of with
xsl:sequence for the variable references always inserts the separator,
even near empty strings which is what I want to avoid.
