ios - hpple:是否有可能获得像 javascript textContent 这样的文本值

Question

hpple中是否可以递归只获取子元素的所有文本内容？ TFHppleElement 类中有任何方法吗？例如 JavaScript

document.getElementById("testdiv").textContent

Answer 1

我正在使用这段代码获取新闻标题的所有内容

NSURL *newURL = [NSURL URLWithString:@"http://somesite"];
        NSData *newsData = [NSData dataWithContentsOfURL: newURL];

        TFHpple *newsParser = [TFHpple hppleWithHTMLData: newsData];

        NSString *newsXpathQueryString = @"//div[@class='item column-1']";
        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 content] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

            news.photo_url = [element objectForKey:@"src"];

            _allNews = newNews;
            [self.tableView reloadData];
        }
    }

你可以使用

news.title = [[element firstChild]content] to get children elements content
