Try this ...

<xsl:template name="mypath">
  <xsl:for-each select="(ancestor-or-self::*|@*)">
    <xsl:choose>
      <xsl:when test=". = /"/>
      <xsl:otherwise>/<xsl:value-of select=
	"concat(name(.), '[', count(preceding-sibling::*[name(current()) =
name(.)]) + 1, ']')"
					/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:for-each>
</xsl:template>

... for an elements-only solution in XSLT, that generates 
"/a[1]/b[3]/c[1]" style xpath for any given context node.

Francis.
