XPath - Attributes selection

Question

I have this code:

<p class='test'>
    Text1
</p>

<p class='test'>
    Text1
</p>

With Hpple (XPath), I need to read the first <p class='test'>, and the second, but I dont know how to do this.

Maybe like:

//p[@class='test'][1]
//p[@class='test'][2]

Thanks

Answer 1

Try this:

#import "TFHpple.h"

NSData  * data      = [NSData dataWithContentsOfFile:@"index.html"];
TFHpple * doc       = [[TFHpple alloc] initWithHTMLData:data];
NSArray * elements  = [doc search:@"//p[@class='test']"];

TFHppleElement * element = [elements objectAtIndex:0];
[e content];              // Tag's innerHTML
[e tagName];              // "a"
[e attributes];           // NSDictionary of href, class, id, etc.
[e objectForKey:@"href"]; // Easy access to single attribute

You have more elements so loop the 'elements' array, in this case you could do [elements objectAtIndex:0] and [elements objectAtIndex:1].

You can take a look at this tutorial: XPath tutorial it wouuld be:

//p[@class='test']
