title: Objective C, xpath query not working
body: <p>I have next html structure </p>
  
  <pre><code>&lt;div class="item column-1"&gt;
    &lt;h2&gt;
      &lt;a href="/news/1172-zimnee-21-12-2014"&gt;
        some text
      &lt;/a&gt;
    &lt;/h2&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to get content of a tag, I'm using this code </p>
  
  <pre><code>NSURL *newURL = [NSURL URLWithString:@"http://mfc.mk.ua/news"];
  NSData *newsData = [NSData dataWithContentsOfURL: newURL];
  
  TFHpple *newsParser = [TFHpple hppleWithHTMLData: newsData];
  
  NSString *newsXpathQueryString = @"//div[@class='item column-1']/h2/a";
  NSArray *newsNodes = [newsParser searchWithXPathQuery: newsXpathQueryString];
  
  NSMutableArray *newNews = [[NSMutableArray alloc] initWithCapacity: 0];
  
  for (TFHppleElement *element in newsNodes)
  {
      News *news = [[News alloc] init];
  
      [newNews addObject: news];
  
      news.title = [[element firstChild] content];
  
      _objects = newNews;
  }
  </code></pre>
  
  <p>But it returning no results. If I do this:   </p>
  
  <pre><code>news.title = [element objectForKey:@"href"]; 
  </code></pre>
  
  <p>then I'm getting results. What I doing wrong? Please help.</p>
