Using wildcards for xpath query in the hpple library for iOS

I am using the hpple library to parse an html document. The document looks something like

<a class="title threadtitle_unread">Promo - 20 Apr 2014</a>
<a class="title">                   Promo - 19 Apr 2014</a>
<a class="title unread">            Promo - 18 Apr 2014</a>
<a class="title special">           Promo - 17 Apr 2014</a>
<a class="title threadtitle_unread">Promo - 16 Apr 2014</a>

I want to retrieve all these nodes using an xpath query. So, I try to do something like

TFHpple *parser = [TFHpple hppleWithHTMLData:htmlData];
NSString *xpathQueryString = @"//a[@class='title']";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:xpathQueryString];

But this understandably returns me only one node which is 

<a class="title">                   Promo - 19 Apr 2014</a>

Can I form an xpath search query with wildcards so it returns me all these nodes? I tried to form the search query as 

NSString *xpathQueryString = @"//a[@class='title']";

but this did not help.

Can I achieve this using hpple? If not, what are my other options?

Thanks

Solution

  • Another possible way is using starts-with() function :

    //a[starts-with(@class,'title')]
