推荐答案

这类工具存在很多问题:

There are a number of problems with such tools:

很少生成的 XPath 表达式是一个好的表达式.除了位置信息之外，没有这样的工具会产生有意义的谓词.

The XPath expression generated rarely is a good one. No such tool will produce meaningful predicates beyond position information.

没有工具(据我所知)会生成一个 XPath 表达式来精确选择一组选定的节点.

There is no tool (to my knowledge) that would generate an XPath expression that selects exactly a set of selected nodes.

除此之外，在没有学习 XPath 的情况下使用这些工具确实是有害的——它们支持无知.

Apart from this, such tools used without learning XPath are really harmful -- they support ignorance.

我建议通过以下书籍和其他资源认真学习 XPath.

I would recommend serious learning of XPath using books and other resources such as following.
