xml - 如何通过id查看xml节点？

Question

我有这个 xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<product name="civil">
<day>Moonday</day>
    <dataseries>
    <data timepoint="3h"> 03:00 </data>
    <data timepoint="6h"> 06:00 </data>
    <data timepoint="9h"> 09:00 </data>
    <data timepoint="12h"> 12:00 </data>
    <data timepoint="15h"> 15:00 </data>
    <data timepoint="18h"> 18:00 </data>
    <data timepoint="21h"> 21:00 </data>
    <data timepoint="24h"> 00:00 </data>
    </dataseries>

如何显示交替节点？这样： 3h, 9h, 15h ... 类似：

  <xsl:for-each select="product/dataseries/data" timepoint="@6h">

但是这段代码是错误的。

Answer 1

尝试关注

  <xsl:for-each select="product/dataseries/data[@timepoint='6h']>

在方括号中可能还有更复杂的条件（例如，使用或运算符、一些算法等）来选择您需要的节点。
