使用replaceAll删除部分XPath表达式

Question

String xpath = "A/B/C[Hello world]/D";

In the above string I have to replace the square brackets and the content between it. Final output should be: A/B/C/D .

I have written the below code but it does not work if there is aa space between Hello and World :

String Xpath1 = xpath.replaceAll("\\[[\\S]+\\]", "");

Answer 1

Your regex matches all non-whitespace characters. Therefore, it will not match a space.

It sounds like you actually want to match all characters except ] :

[^\\]]

Answer 2

这应该做的伎俩：

String xpathResult = xpath.replaceAll("\\[.*\\]", "");
