let file = "file.txt" if let dirs : [String] = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true) as? [String] { let dir = dirs[0] //documents directory let path = dir.stringByAppendingPathComponent(file); let html = String(contentsOfFile: path, encoding: NSUTF8StringEncoding, error: nil)
Edit:
import Foundation let html = "theHtmlYouWannaParse" var err : NSError? var parser = HTMLParser(html: html, error: &err) if err != nil { println(err) exit(1) } var bodyNode = parser.body if let inputNodes = bodyNode?.findChildTags("b") { for node in inputNodes { println(node.contents) } } if let inputNodes = bodyNode?.findChildTags("a") { for node in inputNodes { println(node.getAttributeNamed("href")) //<- Here you would get your files link } } shareimprove this answer
% Encoding URL Args
var myUrl = "http://myurl.com" myUrl = myUrl.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed)! let url = URL(string: myUrl)
URLs
let myURLString = "https://google.com" guard let myURL = URL(string: myURLString) else { print("Error: \(myURLString) doesn't seem to be a valid URL") return } do { let myHTMLString = try String(contentsOf: myURL, encoding: .ascii) print("HTML : \(myHTMLString)") } catch let error { print("Error: \(error)") }
let myURLString = "http://www.yahoo.com" if let myURL = NSURL(string: myURLString) { var error: NSError? let myHTMLString = try! NSString(contentsOfURL: myURL, encoding: NSUTF8StringEncoding) if let error = error { print("Error : \(error)") } else { print("HTML : \(myHTMLString)") } } else { print("Error: \(myURLString) doesn't URL") }
Swift 3: if let url = URL(string: "https://www.google.com/") { do { let contents = try String(contentsOf: url) { print(contents) } else { // Can't unwrap! } } catch { // contents could not be loaded } } else { // the URL was bad! }
let myURLString = "https://google.com" let myHTMLString = try URL(string: myURLString) .flatMap { try Data(contentsOf: $0) } .flatMap { String(data: $0, encoding: .ascii) }
