  <xsl:template match="myElement">
    <xsl:text>numberOccurrences[] = {</xsl:text>
    <xsl:for-each select="foo">
      <xsl:value-of select="count(preceding-sibling::foo[@name=current()/@name])+1"/>
      <xsl:if test="position() != last()">, </xsl:if>
    </xsl:for-each>
    <xsl:text>};</xsl:text>
  </xsl:template>

If efficiency is an issue, xsl:key may be of some utility; it would be easy to
set up a key that does the same work as the preceding-sibling business.
