在处理从网站抓取/获取数据时，我不是最了解的，所以提前道歉。我已在本地将 HTML 文件加载到我的项目中，以便我可以参考和分解元素：

<div class="price">99</div>
<div class="size">M</div>

我想选择这两个 div 类，名称和价格，并相应地提取 99 和 M 的值，我该怎么做？我看着 SwiftSoups

let elements = try doc.select("[name=transaction_id]") // query
let transaction_id = try elements.get(0) // select first element
let value = try transaction_id.val() // get value

但这给了我一个错误。我可以看到您可以选择<P> tags,哪些是段落，但是如何选择特定的 div 类？

再次道歉，如果这是一个初学者的问题。

谢谢你。

如果这些标签具有唯一的类，您可以使用getElementsByClass(_:)函数然后获取第一项，如下所示：

let price = try doc.getElementsByClass("price").first()?.text()
let size = try doc.getElementsByClass("size").first()?.text()
