apply- templates选择子串后

Question

我有以下的XML。

<toc-item>
  <toc-title>
      6A.   <content-style font-style="italic">(Repealed 64 of 1989 s.9)
            </content-style>
  </toc-title>
  <toc-pg>U2/6A</toc-pg>
</toc-item>

我正在运行下面的XSLT。

    <xsl:template name="toc" match="toc">
    <div class="toc">
        <div class="toc-part">
            <table class="toc-div">

    <xsl:analyze-string select="substring-after(.,'.')" regex="(\w)">
        <xsl:matching-substring>
            <xsl:apply-templates select="regex-group(1)"/>
        </xsl:matching-substring>
        <xsl:non-matching-substring>
            <xsl:value-of select="."/>
        </xsl:non-matching-substring>
    </xsl:analyze-string>
</xsl:template>

这里我想要实现的是XML toc-title content-style，<td>后面有一个数字，此处我的输出有2 . < / p>

1. .
之前的数字
2. .之后的内容 如果apply-templates之后除了文字之外没有其他标签，我可以正确地获取文字，并且我想.之后的内容{{1}}，请让我知道我是怎么做的可以做到这一点。

这是demo
