// Prompt: write for me a Swift RSS feed parser that takes in a string of XML data and produces a Post object with a title, description, pubdate, and enclosure fields. Use only the swift standard library
// Sure, here's an example Swift RSS feed parser that uses the Swift standard library to parse a string of XML data and produce a Post object with a title, description, pubdate, and enclosure fields:
import Foundation
struct Post {
let title: String
let description: String
let pubdate: Date
let enclosure: String?
}
func parseXML(xmlString: String) -> [Post] {
guard let xmlData = xmlString.data(using: .utf8) else { return [] }
let parser = XMLParser(data: xmlData)
let rssParserDelegate = RSSParserDelegate()
parser.delegate = rssParserDelegate
parser.parse()
return rssParserDelegate.posts
}
class RSSParserDelegate: NSObject, XMLParserDelegate {
var posts: [Post] = []
var currentElement: String = ""
var currentTitle: String = ""
var currentDescription: String = ""
var currentPubDate: String = ""
var currentEnclosure: String?
func parser(_ parser: XMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String] = [:]) {
currentElement = elementName
if elementName == "enclosure" {
currentEnclosure = attributeDict["url"]
}
}
func parser(_ parser: XMLParser, foundCharacters string: String) {
switch currentElement {
case "title":
currentTitle += string
case "description":
currentDescription += string
case "pubDate":
currentPubDate += string
default:
break
}
}
func parser(_ parser: XMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {
if elementName == "item" {
if let pubDate = parsePubDate(currentPubDate) {
let post = Post(title: currentTitle.trimmingCharacters(in: .whitespacesAndNewlines),
description: currentDescription.trimmingCharacters(in: .whitespacesAndNewlines),
pubdate: pubDate,
enclosure: currentEnclosure)
posts.append(post)
}
currentTitle = ""
currentDescription = ""
currentPubDate = ""
currentEnclosure = nil
}
currentElement = ""
}
private func parsePubDate(_ pubDate: String) -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "EEE, dd MMM yyyy HH:mm:ss Z"
return dateFormatter.date(from: pubDate)
}
}
// To use this parser, you can call the parseXML function and pass in a string of XML data. It will return an array of Post objects:
let xmlString = """
<?xml version="1.0" encoding="UTF-8"?>
