  • Parses HTML (XML coming soon)
  • Easy access to tag content, name, and attributes.

INSTALLATION

  • Drag the "Hpple" directory to your project.
  • Add the libxml2.2.dylib framework to your project and search paths as described at Cocoa with Love

More documentation and short screencast coming soon...

USAGE

See TFHppleHTMLTest.m in the Hpple project for samples.

#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

TODO

  • Internal error catching and messages
  • CSS3 selectors in addition to XPath
