正则表达式精确匹配字符串

Question

I have the following string:

E:\Confluence_Attachments\ver003\10\85\1835010\124\165\4915874\19169322\1

How do I get the substring that begins with ver003?

I want only this part of the string:

ver003\10\85\1835010\124\165\4915874\19169322\1

Answer 1

If I understand your question, you can use .+ and group the desired elements with () and then use a replaceAll like

String s = "E:\\Confluence_Attachments\\ver003\\10\\85\\"
        + "1835010\\124\\165\\4915874\\19169322\\1";
System.out.println(s.replaceAll(".+(ver003.+)", "$1"));

Which outputs (as requested)

ver003\10\85\1835010\124\165\4915874\19169322\1
