html - 如何在 iOS 中分隔 xml 标记内的值

Question

在调用 API 时，我收到以下格式的响应:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<response>
    <status>success</status>
    <ads>&lt;a href='http://52.7.130.201/oapi/clickAd;jsessionid=679E3CFF39C3D7792E7F6915318E3156.soma-i-915abc39'&gt;&lt;img src='http://52.7.130.201/oapi/getAd;jsessionid=679E3CFF39C3D7792E7F6915318E3156.soma-i-915abc39'/&gt;&lt;/a&gt;</ads>
</response>

我正在检索标签内的整个值并存储在一个字符串内。下面是它的代码:

 NSString *html = [xml.documentRoot getNamedChild:@"ads"].text;

现在我需要将值分别存储在“ads”标签的“href”和“img src”中。该怎么做？请帮助..

//as the data you have provided

NSString *html =@"<a href='http://52.7.130.201/oapi/clickAd;jsessionid=679E3CFF39C3D7792E7F6915318E3156.soma-i-915abc39'><img src='http://52.7.130.201/oapi/getAd;jsessionid=679E3CFF39C3D7792E7F6915318E3156.soma-i-915abc39'/></a&gt";



    NSString *href;
    NSString *img_src;
    NSRange range = [html rangeOfString:@"href=\'"];
    NSString  *tempUrl=[html substringFromIndex:range.location+6];
    NSRange range2 = [tempUrl rangeOfString:@"\'"];
    href=[tempUrl substringWithRange:NSMakeRange(0, range2.location)];

    range = [html rangeOfString:@"img src=\'"];
    tempUrl=[html substringFromIndex:range.location+9];
    range2 = [tempUrl rangeOfString:@"\'"];
    img_src=[tempUrl substringWithRange:NSMakeRange(0, range2.location)];



    NSLog(@"your href is %@ and your img_src is %@",href,img_src);
