Re: [xsl] Inserting a separator only between non-empty strings (XSLT 2)

[Yves Forkl <Y.Forkl@xxxxxx>]

Thank you very much for your explanation, Michael. Now I understand 
better why things have to be this way.

The solution you suggested works perfectly for me. I am just a bit 
disappointed that XSLT 2 doesn't provide with me a more elegant 
construct that would make life even easier for me (like XSLT 2 already 
did in a lot of cases). :-)

Unfortunately, this won't work, as xsl:sequence only allows to use the 
select attribute here, not its element content. However, adapting it a 
little I get

<xsl:variable name="concat" select="($a, $b, $c)"/>
<xsl:value-of separator="|" select="$concat[string-length(.) gt 0]"/>

which seems to work (but I am not sure). Anyway, I prefer Michael's 
solution.
