[iphone-objective C]去掉一段String中的HTML標籤

本來想找一個如何能把HTML的String，解析出來的工具。暫時還沒有找到。但是找到一段很不錯的code。

 

可以移調裡面的標籤。 

- (NSString *)flattenHTML:(NSString *)html {    NSScanner *theScanner;    NSString *text = nil;    theScanner = [NSScanner scannerWithString:html];    while ([theScanner isAtEnd] == NO) {        // find start of tag        [theScanner scanUpToString:@"<" intoString:NULL] ;         // find end of tag        [theScanner scanUpToString:@">" intoString:&text] ;        // replace the found tag with a space        //(you can filter multi-spaces out later if you wish)        html = [html stringByReplacingOccurrencesOfString:                           [ NSString stringWithFormat:@"%@>", text]                     withString:@" "];    } // while //        return html; 

}
