使用正则表达式切割字符串

Question

我想使用regexp剪切字符串，但不要剪切正则表达式部分......

String path ="house/room/cabinet/my_books/bought/2011/adventure/Black-Ship01/312 pages/...";
String[] substract=path.split("my_");
path=substract1[1].toString();// books/bought/2011/adventure/Black-Ship01/312 pages/...
String[] substract2=path.split("-Ship.."); //split using -Ship and two random simbols
path=substract[1].toString();

RESULT:   path= "books/bought/2011/adventure/Black"
Should be path= "books/bought/2011/adventure/Black-Ship01"

所以如何添加-Ship01 ??

Answer 1

尝试使用positive lookbehind：String[] substract2=path.split("(?<=-Ship..)")。这与模式匹配，但不消耗字符。

Answer 2

我现在想不出更好的方法。但你可以这样做：

public class NewClass
{
    public static void main(String[] args)
    {
        String finalStr = "";
        String patternStr = "(-Ship..)";
        String path ="house/room/cabinet/my_books/bought/2011/adventure/Black-Ship01/312 pages/...";
        String[] substract2 = path.split(patternStr);       
        System.out.println("substract2="+Arrays.toString(substract2));      
        Pattern pattern = Pattern.compile(patternStr);
        Matcher matcher = pattern.matcher(path);    
        matcher.find();
        System.out.println("g0="+matcher.group(0));
        finalStr = substract2[0]+matcher.group(0);
        System.out.println("finalStr="+finalStr);
      }     
}
