解析HTML表--Swift3-ParseanHTMLtable—Swift3

1  

You need an HTML parser to go through the response HTML. Do not even think about using regex. The answer below uses HTMLReader, which you can add to your project via CocoaPods. Playground kept crashing on me so I converted your code an IBAction instead:

您需要一个HTML解析器来完成响应HTML。甚至不要考虑使用正则表达式。下面的答案使用HTMLReader,您可以通过CocoaPods将其添加到项目中。游乐场一直撞在我身上,所以我将你的代码改为IBAction:

import UIKit
import MapKit
import HTMLReader

class ViewController: UIViewController {
    var result = [String: [String: AnyObject]]()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func loadHTML(_ sender: AnyObject) {
        let url = URL(string: "https://vtlottery.com/games/instant-tickets/outstanding-prizes")!
        let session = URLSession.shared

        let request = NSMutableURLRequest(url: url)
        request.httpMethod = "POST"
        request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData

        let paramString = "data=Hello"
        request.httpBody = paramString.data(using: String.Encoding.utf8)

        let task = session().dataTask(with: request as URLRequest) { data, response, error in
            guard let data = data, let _ = response where error == nil else {
                print("error")
                return
            }

            var index = 0

            // Many columns has newlines, tabs or spaces for their
            // textual content. Here, define a character set to trim
            // them off
            let spaceCharacterSet = CharacterSet(charactersIn: "\n\t ")

            let html = HTMLDocument(data: data, contentTypeHeader: "text/html; charset=utf-8")
            for node in html.nodes(matchingSelector: "#tblData tbody tr") {
                let columns = node.nodes(matchingSelector: "td")

                let topPrices = columns[3].nodes(matchingSelector: "p").map { $0.textContent }
                let unclaimedTopPrices = columns[4].nodes(matchingSelector: "p").map { $0.textContent }

                // You have to open the Web Inspector in Safari to grab
                // the table's structure
                let rowData: [String: AnyObject] = [
                    "Price"                : columns[0].textContent.trimmingCharacters(in : spaceCharacterSet),
                    "Game #"               : columns[1].textContent.trimmingCharacters(in : spaceCharacterSet),
                    "Game Name"            : columns[2].textContent.trimmingCharacters(in : spaceCharacterSet),
                    "Top Prices"           : topPrices,
                    "Unclaimed Top Prizes" : unclaimedTopPrices,
                    "Total Unclaimed"      : columns[5].textContent.trimmingCharacters(in : spaceCharacterSet),
                    "% Sold"               : columns[6].textContent.trimmingCharacters(in : spaceCharacterSet),
                    "# of tickets"         : columns[7].textContent.trimmingCharacters(in : spaceCharacterSet)
                ]

                index += 1
                self.result["row \(index)"] = rowData
            }

            // It's better if you put a breakpoint on the line below.
            // Swift 3's logging is too verbose at the moment.
            print(self.result["row 1"]!["Unclaimed Top Prizes"])
        }

        task.resume()
    }
}
