XPATH 1.0 : 匹配非空元素 [英] XPATH 1.0 : match not empty elements

问题描述

我需要匹配既不包含 PCDATA 也不包含子元素的元素.

I need to match elements that contain neither PCDATA nor child elements.

我试过了:

.//myelem[count(nodes())=0]

但是 nodes() 在 XPATH 1.0 中是未知的.

but nodes() is unknown in XPATH 1.0.

您所知道的在 XPATH 1.0 中执行此操作的最简洁方法是什么?

What is the most concise way that you know of to do this in XPATH 1.0 ?

推荐答案

You was close - it is node(), not nodes():

You were close - it is node(), not nodes():

.//myelem[count(node()) = 0]

或者，更地道的:

.//myelem[not(node())]
