Question

所以，我有我的XML文件，我正在尝试为预订中的每个DropPoint检索DropPoint的名称，以便将其放在我的表格上。每个预留中的DropPoint字段由IDREF引用。

有没有办法将指定解析到我的表格而不保存id并迭代所有DropPoints以找出我正在处理哪一个？

这是XML文件：

Answer 1

如果您设置了密钥

<xsl:key name="drop-point" match="DropPoints/DropPoint" use="@id">

然后在处理Reservation时，您可以使用<xsl:value-of select="key('drop-point', DropPoint/@id)/Designation"/>输出引用的Designation的{{1}}。

另请注意，DropPoint应为<xsl:template match="/System/Reservations/">，不得尾随<xsl:template match="/System/Reservations">。
