[SOLVED] Objective C - hpple getting text from inside TR tags

Objective C - hpple getting text from inside TR tags

First time here.

Im attempting to build a Iphone app that pulls a single string from a HTML table on a website using hpple, The example of the website is here: http://tsy.acislive.com/pip/stop_simulator_title.asp?naptan=37020349&pscode=22&dest=&offset=1

and the code of the website:

<body class="ss_title">
<table class=piptitle cellpadding='0' cellspacing='0' width="100%"><tr><td align="center" valign="middle">Tannery Street - 02:32 (+1h)</td></tr></table>
</body>

I have tried the following method inside my app to get the text "Tannery Street - 02:32 (+1h):

-(void)loadTitleTable{
    NSLog(@"Load Title Method Called Successfully");

                  NSData *htmlData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://tsy.acislive.com/pip/stop_simulator_title.asp?naptan=37020349&pscode=22&dest=&offset=1"]];
                  TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData];
                  NSArray *elements  = [xpathParser searchWithXPathQuery:@"//tr/td"];
                  TFHppleElement *element = [elements objectAtIndex:0];
                  NSString *myTitle = [[element firstChild] content];
                  NSLog(myTitle);
                  _stopNOlabel.text = myTitle;
    NSLog(@"Array: %@", elements);
}

I have tried outputting the array using NSLog and this is what the array outputs:

Array: ( "{\n nodeAttributeArray = (\n {\n attributeName = align;\n nodeContent = center;\n },\n {\n attributeName = valign;\n nodeContent = middle;\n }\n );\n nodeName = td;\n raw = \"\";\n}" )

I hope somebody here will be able to help me resolve this and set the label to the text string.

Thanks. Damien

Solution

Found the best way to do this instead of using Happle is to use a web backend and use JSON data from that rather than scraping in HTML.
