我的代码：

<xsl:for-each select="Transaction/Record[@Name='IDE']" >
<xsl:choose>
<xsl:when test="../Record[@Name='BGM']/BGM01.='414'">
<xsl:call-template name="ChangeResponse"/>
</xsl:when>
<xsl:when test="../Record[@Name='BGM']/BGM01.='406'">
<xsl:call-template name="DropRequest"/>
</xsl:when>
</xsl:choose>
</xsl:for-each>

问题是BGM和IDE是兄弟节点，当IDE是我的当前节点时，我需要转到父节点以获取BGM记录，这导致只返回第一个BGM值。我正试图找到一种方法来获得直接位于IDE值之前的BGM值。我尝试使用前面的同级，但它先查看前面的IDE值，然后再查看之前的BGM值。我需要呆在每个IDE的当前节点中，然后评估前一个BGM的值，但BGM是IDE的兄弟，所以当我在IDE启动时，不确定如何使用xpath来获得BGM。

Answer 1

在xsl:for-each select="Transaction/Record[@Name='IDE']"内部，您应该能够使用preceding-sibling::Record[@Name = 'BGM'][1]找到从当前Record开始的第一个这样的前一个同级。因此，在Record Name = "IDE" RecNum = "8"的示例中，它将选择Record Name = "BGM" RecNum = "2"。
