xpath查找不包含子节点的节点 [英] xpath find node that does not contain child

问题描述

我正在尝试创建一些xpath，该xpath将查找不包含img标记的所有a标记，以便诸如

I'm trying to create some xpath that will find all a tags that do not contain img tags, so that something such as

<a href="http://aol.com">link</a>

匹配，但是

<a href="http://yahoo.com"><img src="http://yahoo.com/logo.png"></a>

没有.

我当然可以分两部分进行搜索，但是我敢肯定必须使用xpath进行此操作.

Of course I could do this in a two-part search but I'm sure there must be some way to do this with xpath.

推荐答案

//a[not(img)]

请尝试并尽量避免使用//.另请注意，这将仅排除直接 包含img的a.

Try and avoid the // if you can, though. Also note this will only exclude as that directly contain imgs.
