在两个已知字符串之间搜索一个字符串 [英] Search for a string between two known strings

问题描述

我有一个包含以下内容的字符串:

I have a String with this content:

href="http://www.website.com/" /> [...] [...]

我只想获取字符串的中心部分.如何获得@"href ="和@""/>"

I just want to get the central part of the string. How is it possible to get the part between @"href="" and @"" />"

注意:即使看起来像xml代码，它也位于NSString内部.

Note: Even if it looks like xml-code, it is inside of a NSString.

推荐答案

我明白了！

这是代码(写得不太好):

This is the code (not very nice written):

NSRange rr2 = [content rangeOfString:@"href=\""];
    NSRange rr3 = [content rangeOfString:@"\" />"];
    int lengt = rr3.location - rr2.location - rr2.length;
    int location = rr2.location + rr2.length;
    NSRange aa;
    aa.location = location;
    aa.length = lengt;
    theString = [theString substringWithRange:aa];
