我需要将网站的内容解析为我的应用程序中的表格视图。我尝试了 hpple 并且在某些测试用例中它可以工作。但在我的具体情况下，我无法让它工作...... HTML：

</html>

该页面包含两个主要元素 ( <table></table>)，我想用它们来填充我的 UITableView。

我的目标是每个表有一个部分，并且在每个部分中包含表的所有内容。节标题名称应该是“日期”。

TFHpple *Parser = [TFHpple hppleWithHTMLData:HtmlData];

NSString *XpathQueryString = @"/html/body/a";
NSArray *Nodes = [Parser searchWithXPathQuery:XpathQueryString];

for (TFHppleElement *element in Nodes) {
    NSString *temp = [[element firstChild] content];
    if (temp.length == 10) {
        [Day addObject:temp];
    }
}

在我NSMutableArray *Day的保存日期，这工作正常。我得到 2 个名称正确的部分。但是当我尝试接收表格内容时，我无法让它工作......我想要类似的东西

tableElement* newElement = [[tableElement alloc] init];
newElement.day = @"07.07.2015";
newElement.team = @"A";
newElement.name = @"First";
newElement.nr = @"3";
newElement.mate = @"";
newElement.spot = @"";
newElement.map = @"";
newElement.status = @"Test";

然后我可以将newElement日期一的所有（s）存储在一个数组中，并将日期二的所有元素存储在另一个元素中。

编辑：例如newElement.day = @"07.07.2015";，当然需要像newElement.day = [[hppleparse firstChild] content];

这可以通过HTMLKit轻松实现。

以下是使用您提供的 HTML 可以执行的操作的几个示例：

HTMLDocument *document = [HTMLDocument documentWithString:html];
NSMutableArray *days = [ NSMutableArray array];
NSArray *links = [document querySelectorAll:@"a"];
for (HTMLElement *link in links) {
  if (link.textContent.length == 10) {
    [days addObject:link.textContent];
  }
}

// For example you can:
// Get all <tr> elements that are children of the table with className 'k'
NSArray *tableKRows = [document querySelectorAll:@"table.k > tr"];

// Get all <td> elements that are descendants of the table with className 'k'
NSArray *tableKData = [document querySelectorAll:@"table.k td"];

// Collect content of all <td> elements in `array`
NSMutableArray *array = [NSMutableArray array];
for (HTMLElement *td in tableKData) {
  NSString *content = [td.textContent stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
  [array addObject:content];
}

如果您需要任何进一步的帮助，请告诉我。

HTMLKit 是一个纯 Objective-C HTML 解析器，支持 CSS3 选择器。它不是 libxml 或任何其他库的包装器，而是一个完整的符合 WHATWG HTML 规范的实现。
