XPath 查找具有特定文本的特定节点 [英] XPath finding certain node with certain text

问题描述

所以我有一个类似的问题:

So I had a question regarding something similar to that at:

获取一个父节点及其子节点，其中子节点具有特定文本

但是情况发生了变化，我发现我的上述想法有些问题.我现在正在尝试查找具有特定文本的节点，因为当我使用 29 时，它似乎还会找到包含 2999 或其他任何包含 29 的节点.

But the situation change and I find some problems with my above idea. I am now trying to find a node with specific text because it seems when I use 29 it will also find nodes that has 2999 or anything else that has 29 in it.

所以我的问题是我该如何转向:

So my question is how can I turn :

$myvar = $xpath->query('(///*[text()[contains(., "something")]])');

所以它会寻找带有特定文本的节点.不适用于具有"特定文本的节点.

so it will look for node with certain text. not for a node that "has" certain text.

推荐答案

只需使用 //*[text() = "29"] 而不是 contains().

Just use //*[text() = "29"] instead of contains().
