我试图弄清楚这一点，但已经一周了。有人对如何进行有任何建议吗？

我想：在 splitOne 中的 foreach 条目（任何长度的逗号分隔字符串），与每个 splitTwo （任何长度的逗号分隔字符串）进行比较。如果有匹配，则显示节点。如果没有，不要。

如果这是 C#，这已经结束了。但是在 XSLT1.0（并且只有 XSLT 1.0）中，这对我来说是个大问题。

splitOne 是 OUTER LOOP，splitTwo 是 INNERLOOP。

我对 XSLT 以外的其他方法持开放态度，但最终产品必须是 XML。

这是我正在运行的 XML。

    <Program Control="PSF0060 Start Miles (OM)" Value="PSF0060 Start Miles (OM)" assocGroups="1,2" />

  </Module>
</application>

我只需要上面的程序节点，其中 assocGroup 中的值也在 $Groups_From_Logged_In_User

我会做一个身份转换，只<Program>专门处理元素。我会递归地拆分第一个 CSV 并查看它是否出现在assocGroups属性中。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">

  <xsl:param name="Groups_From_Logged_In_User"/>

  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="Program">
    <!-- We have to append a ',' to $Groups_From_Logged_In_User so that we still get 
         something back from substring-before(...,',') in the last iteration -->
    <xsl:param name="list" select="concat($Groups_From_Logged_In_User,',')"/>
    <!-- We also add commas around @assocGroups because we want to check for appearances of ",1," 
         rather than "1", as this would also be found in "11", which is not what we want to find -->
    <xsl:param name="assocGroups" select="concat(',',@assocGroups,',')"/>
    <xsl:choose>
      <!-- We we've chipped everything off the list, we quit -->
      <xsl:when test="$list=''"/>
      <!-- Now we chip off the first bit of the list, wrap it in commas and see whether it appears in $asscoGroups -->
      <xsl:when test="contains($assocGroups,concat(',',substring-before($list,','),','))">
        <xsl:copy-of select="."/>
      </xsl:when>
      <!-- If we didn't find anything, we drop the first value and recurse. -->
      <xsl:otherwise>
        <xsl:apply-templates select=".">
          <xsl:with-param name="list" select="substring-after($list,',')"/>
          <xsl:with-param name="assocGroups" select="$assocGroups"/>
        </xsl:apply-templates>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
</xsl:stylesheet>
