本来想找一个如何能把HTML的String，解析出来的工具。暂时还没有找到。但是找到一段很不错的code。

 

可以移调里面的标签。 

- (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; }
