The xsl:for-each select="tokenize()" changes the context item, so key() no longer knows which tree to search in. Change it to

  <xsl:variable name="root" select="/"/>
  <xsl:template match="/">
    <body>
      <xsl:for-each select="tokenize(example/bar/@ids, ',')">
        <xsl:value-of select="."/>:<xsl:value-of
select="key('index', ., $root)" />
      </xsl:for-each>
    </body>
  </xsl:template>
