XSLT 1.0.我需要在以下表达式中选择几个节点并排除其他节点

Question

>我需要仅包含来自 E0 兄弟的所有 01 个 recordCode 节点，但需要忽略 E2 和 E3 下的节点，我使用以下代码获得所有 01 后跟 E0。不确定如何创建上面的密钥，这只会导致一个节点的所有 01 都只遵循 E0。这是我目前的 xslt。

Answer 1

只是猜测。但基本上您应该按如下方式更改密钥：
（使用密钥修复进行更新）

<xsl:key name="kApproverDetailArray" match="faRecord[recordCode='01']"
         use="generate-id(
              preceding-sibling::faRecord[recordCode='E0' or recordCode='E2'][1])" />

有了它，您可以遍历以下"faRecord[recordCode='01'] faRecord[recordCode='E0' ]：

 <xsl:template match="facXML">
    <xsl:for-each select="faRecord[recordCode='E0' ]">
      <xsl:for-each select="key('kApproverDetailArray', generate-id())  ">
         <!-- do something -->
      </xsl:for-each>
  </xsl:for-each>
</xsl:template>
