//Remove HTML tags-(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:[NSStringstringwithformat:@"%@>", text] withstring:@""]; }returnhtml;}
