Another suggestion

   <xsl:value-of select="($a, $b, $c)[.]" separator="|" />

if content contains nodes, including empty ones which you don't want 
output, you can change it to:

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

if you do not want relevant whitespace-only nodes to appear (you can 
also use strip-space or) :

   <xsl:value-of select="($a, $b, $c)[normalize-space(.)]" separator="|" />
