Open Your project in Xcode and drag and drop all `.h`/`.m` files into an appropriate folder 16 | 2. In the project settings add `/usr/include/libxml2` to the “Header search paths” field 17 | 3. Ctrl-Click the Frameworks group choose “Add -> Existing Frameworks” and from the list choose `libxml2.dylib` 18 | 19 | ## Usage 20 | 21 | ```objc 22 | NSError *error = nil; 23 | NSString *html = 24 | @"
    " 25 | "
    • " 26 | "
    • " 27 | "
" 28 | "Hello World 1" 29 | "Hello World 2"; 30 | HTMLParser *parser = [[HTMLParser alloc] initWithString:html error:&error]; 31 | 32 | if (error) { 33 | NSLog(@"Error: %@", error); 34 | return; 35 | } 36 | 37 | HTMLNode *bodyNode = [parser body]; 38 | 39 | NSArray *inputNodes = [bodyNode findChildTags:@"input"]; 40 | 41 | for (HTMLNode *inputNode in inputNodes) { 42 | if ([[inputNode getAttributeNamed:@"name"] isEqualToString:@"input2"]) { 43 | NSLog(@"%@", [inputNode getAttributeNamed:@"value"]); //Answer to first question 44 | } 45 | } 46 | 47 | NSArray *spanNodes = [bodyNode findChildTags:@"span"]; 48 | 49 | for (HTMLNode *spanNode in spanNodes) { 50 | if ([[spanNode getAttributeNamed:@"class"] isEqualToString:@"spantext"]) { 51 | NSLog(@"%@", [spanNode rawContents]); //Answer to second question 52 | } 53 | } 54 | 55 | [parser release]; 56 | ``` 57 | --------------------------------------------------------------------------------
