XPath selection by innertext
提问by kdt
I'm trying to extract an element with a particular innertext from a parsed XML document. I know that I can select an element that has a child with a particular innertext using //myparent[mychild='foo'], but I actually just want to select the "mychild" element in this example.
我试图从解析的 XML 文档中提取具有特定内部文本的元素。我知道我可以使用 选择一个具有特定内部文本的子元素的元素//myparent[mychild='foo']，但实际上我只想在此示例中选择“mychild”元素。
<myparent>
<mychild>
foo
</mychild>
</myparent>
What would be the XPath query for "foo" that would return the "mychild" node?
返回“mychild”节点的“foo”的 XPath 查询是什么？

Have you tried this?
你试过这个吗？
//myparent/mychild[text() = 'foo']
Alternatively, you can use the shortcut for the selfaxis:
或者，您可以使用self轴的快捷方式：
//myparent/mychild[. = 'foo']

Matt said it, but the full solution:
马特说过，但完整的解决方案：
//myparent[mychild='foo']/mychild
回答by Sándor Krisztián
You might consider using the containsfunction to return true/false if the test was found like so:
contains如果像这样找到测试，您可能会考虑使用该函数返回真/假：
//mychild[contains(text(),'foo')]
