如何从Time字符串中获取location，details和HTML的价值

由于

Answer 1

您可以使用substringWithRange。在两个范围之间传递HTML标记，您将获得它们之间的字符串。

NSRange r1 = [s rangeOfString:@"<b>Time:</b>"];
NSRange r2 = [s rangeOfString:@"<br />"];
NSRange rSub = NSMakeRange(r1.location + r1.length, r2.location - r1.location - r1.length);
NSString *sub = [s substringWithRange:rSub];

Answer 2

您可以使用hpple！

如：

#import "TFHpple.h"

NSData  * data      = [NSData dataWithContentsOfFile:@"index.html"];

TFHpple * doc       = [[TFHpple alloc] initWithHTMLData:data];
NSArray * elements  = [doc search:@"//a[@class='sponsor']"];

TFHppleElement * element = [elements objectAtIndex:0];
[e text];                       // The text inside the HTML element (the content of the first text node)
[e tagName];                    // "a"
[e attributes];                 // NSDictionary of href, class, id, etc.
[e objectForKey:@"href"];       // Easy access to single attribute
[e firstChildWithTagName:@"b"]; // The first "b" child node
