XPath 跟随多个条件的兄弟

Question

我有以下 xml 文档。我正在尝试选择具有相同 value2 且 value3 未关闭的 sibling 的任何子项。

<root>
  <child>
    <value1>Type A</value1>
    <value2>Class 1</value2>
    <value3>Active</value3>
  </child>
  <child>
    <value1>Type B</value1>
    <value2>Class 1</value2>
    <value3>Closed</value3>
  </child>
  <child>
    <value1>Type C</value1>
    <value2>Class 2</value2>
    <value3>Active</value3>
  </child>
  <child>
    <value1>Type D</value1>
    <value2>Class 2</value2>
    <value3>Active</value3>
  </child>
  <child>
    <value1>Type E</value1>
    <value2>Class 3</value2>
    <value3>Active</value3>
  </child>
</root>

我的尝试是:

//child[following-sibling::child/value2=value2 and value3!='Closed']

但这并没有达到将多个条件应用于以下兄弟函数的预期结果。

有什么想法吗？

Answer 1

//child[value2 = following-sibling::child[not(value3 = 'Closed')]/value2]

要应用于任何同级，请将 following-sibling 和 preceding-sibling 轴联合起来。

//child[value2 = (following-sibling::child | preceding-sibling::child)[not(value3 = 'Closed')]/value2]
