<p>I have rewritten your code with <a href="https://github.com/iabudiab/HTMLKit" rel="nofollow">HTMLKit</a>. It looks like this:</p>

<pre><code>NSURL *papersURL = [NSURL URLWithString:@"http://www.arxiv.org/list/cond-mat/recent"];
NSData *papersHTMLData = [NSData dataWithContentsOfURL:papersURL];
NSString *htmlString = [[NSString alloc] initWithData:papersHTMLData encoding:NSUTF8StringEncoding];

HTMLDocument *document = [HTMLDocument documentWithString:htmlString];

NSArray *divs = [document querySelectorAll:@"div[class='list-title']"];

for (HTMLElement *element in divs) {
    NSLog(@"%@", element.textContent);
}
</code></pre>

<p>Back to your question in the comment: </p>

<blockquote>
  <p>Could you give some useful links that you find good to learn about HTMLKit?</p>
</blockquote>

<p>You can check out the examples on the project's GitHub page. The source code is documented and using it is relatively straightforward. If you have basic HTML &amp; CSS experience then using HTMLKit would be just as easy. Unfortunately there are no other resources it to learn it yet.</p>
Parsing a web page with TFHpple
<p>I'm trying to write a very simple iOS app that will parse a webpage (<a href="http://arxiv.org/list/cond-mat/recent" rel="nofollow">http://arxiv.org/list/cond-mat/recent</a>) and display a simplified version of it. I chose to use TFHpple to parse this page. I want to get titles of papers and display them in the TableViewController. The HTML container for paper descriptions looks like:</p>

<pre><code>&lt;div class="list-title"&gt;
&lt;span class="descriptor"&gt;Title:&lt;/span&gt; Encoding Complexity within Supramolecular Analogues of Frustrated  Magnets
&lt;/div&gt;
</code></pre>

<p>Function that I use to parse and get the values is the following (thanks to raywenderlich.com):</p>

<pre><code>- (void) loadPapers{
    NSURL *papersURL = [NSURL URLWithString:@"http://www.arxiv.org/list/cond-mat/recent"];
    NSData *papersHTMLData = [NSData dataWithContentsOfURL:papersURL];

    TFHpple *papersParser = [TFHpple hppleWithHTMLData:papersHTMLData];

    NSString *papersXpathQueryString = @"//div[@class='list-title']";
    NSArray *papersNodes = [papersParser searchWithXPathQuery:papersXpathQueryString];

    NSMutableArray *newPapers = [[NSMutableArray alloc] initWithCapacity:0];

    for (TFHppleElement *element in papersNodes){
        Paper *paper = [[Paper alloc] init];
        [newPapers addObject:paper];

        paper.title = [[element firstChild] content];
    }

    _objects = newPapers;
    [self.tableView reloadData];

}
</code></pre>

<p>This function is supposed to parse the entire HTML page and return data into TableView. However, when I try it returns empty objects into the paperNodes array. Basically, the number of the elements is correct (~25), but they're all empty and I am not sure why.</p>

<p>Any help is greatly appreciated! Thanks!</p>
