[英]regular expression for finding string between [[ ]] and {{}}
How could I find string between [[
]]
? 我怎么能在
[[
]]
之间找到字符串? After searching a answer I find this method below, but I cannot find the regular expression for [[
]]
, neither for {{
}}
. 在搜索答案后,我在下面找到了这个方法,但我找不到
[[
]]
的正则表达式, {{
}}
也没有。
What I want to do is to find eg [[abc]]XXXXXXXXXX[[def]]
, and save abc
, def
as a ArrayList. 我想要做的是找到例如
[[abc]]XXXXXXXXXX[[def]]
,并将abc
, def
保存为ArrayList。
String s = "[[abc]]XXXXXXXXXX[[def]]";
Pattern p = Pattern.compile("[[(.*?)]]")
Matcher m = p.matcher(s);
if (m.find()) {
System.out.println(m.group(i)); // => "abc","def"
}
You must double escape the opening square brackets (you can do the same with the closing) since they are used to define character classes: 您必须双重转义开头方括号(您可以对结束执行相同操作),因为它们用于定义字符类:
Pattern p = Pattern.compile("\\[\\[(.*?)]]");
(exactly the same with curly braces, that are used for quantifiers) (与花括号完全相同,用于量词)
