I’ve got anchors with multiple classes - something like <a class=“h5 image js-catalog-click”…

Tried Hpple, Kanna - no luck with XPath like “//a[@class=‘h5 image js-catalog-click’]”

Any ideas how to get the data from such HTML?

Very grateful to the author, and now if you need to use, you need to change a few code, first of all need to change the HTTP for the HTTPS

I changed a place, you can set the author’s head display:grinning:

-(void)loadContributors {
    // 1
    NSURL *contributorsUrl = [NSURL URLWithString:@"https://www.raywenderlich.com/about"];
    NSData *contributorsHtmlData = [NSData dataWithContentsOfURL:contributorsUrl];
    
    // 2
    TFHpple *contributorsParser = [TFHpple hppleWithHTMLData:contributorsHtmlData];
    
    // 3
    NSString *contributorsXpathQueryString = @"//ul[@class='team-members']/li";
    NSArray *contributorsNodes = [contributorsParser searchWithXPathQuery:contributorsXpathQueryString];
    
    // 4
    NSMutableArray *newContributors = [[NSMutableArray alloc] initWithCapacity:0];
    for (TFHppleElement *element in contributorsNodes) {
        // 5
        Contributor *contributor = [[Contributor alloc] init];
        [newContributors addObject:contributor];
        // 6
        //寻找子标签
        for (TFHppleElement *child in element.children) {
            //如果是a  If it is a a tag
            if ([child.tagName isEqualToString:@"a"]) {
                // 7
                //                    contributor.imageUrl = [@"https://www.raywenderlich.com/about" stringByAppendingString:[child objectForKey:@"src"]];
                //继续寻找子标签  Continue to search for child Tags
                for (TFHppleElement *childA in child.children) {
                    //如果是src  If it is src  Here will return the image of URL
                    contributor.imageUrl = [childA objectForKey:@"src"];
                }
                
                    
//                    NSString *str = [temp objectForKey:@"img"];
                
            } else if ([child.tagName isEqualToString:@"h3"]) {
                // 8
                contributor.name = [[child firstChild] content];
            }
        }
    }
    
    // 9
    _contributors = newContributors;
    [self.tableView reloadData];
}
