I've to parse an Html for my iOS app. I read on the web that I should use the Xpath and I found the library TFHpple. I see that this library uses the XpathQuery

I'm interesting in two information about this html:
this <title>Sito 4/home</title>
this <span style="color: rgb(255, 255, 255); ">Scadenza: 29 Ago 2013</span>
For now I wrote this code:
- (void)loadDataFromHtml {
NSURL *url = [NSURL URLWithString:stringUrl];
NSData *data = [NSData dataWithContentsOfURL:url];
TFHpple *parser = [TFHpple hppleWithHTMLData:data];
NSString *XpathQueryStringTitle = @"//title";
NSArray *nodes = [parser searchWithXPathQuery:XpathQueryStringTitle];
NSMutableArray *dataArray = [[NSMutableArray alloc]initWithCapacity:0];
for (TFHppleElement *element in nodes) {
HtmlData *htmlData = [[HtmlData alloc]init];
[dataArray addObject:htmlData];
htmlData.title = [[element firstChild]content];
htmlTitle = htmlData.title;
htmlTitle = [htmlTitle substringToIndex:6];
htmlTitle = [htmlTitle stringByReplacingOccurrencesOfString:@" " withString:@""];
}
}
(Based on this tutorial: http://www.raywenderlich.com/14172/how-to-parse-html-on-ios)
Now my question is how I can find the second information I need? Should I made another NSString to obtain the second information? Can you help me to solve this problem?
Thank you
