HTML Question

SWIFT 3 - take out html tags from string taken from JSON web url

I was wondering how can HTML tags be stripped out of JSON from a web url. Do I have to use

of something similar.

So I am looking to strip out the html tags that are in the summary value. I looked around abit and it says NSString can be used but I was not sure if that was something that could be implemented into Swift 3. Any Help would be appreciated.

My code:

import UIKit
import Alamofire

struct postinput {
let mainImage : UIImage!
let name : String!
let author : String!
let summary : String!


class TableViewController: UITableViewController {

var postsinput = [postinput]()

var mainURL = ""

typealias JSONstandard = [String : AnyObject]

override func viewDidLoad() {
// Do any additional setup after loading the view, typically from a nib.
callAlamo(url: mainURL)

func callAlamo(url : String){
Alamofire.request(url).responseJSON(completionHandler: {
response in




func parseData(JSONData : Data) {
do {
var readableJSON = try JSONSerialization.jsonObject(with: JSONData, options: .mutableContainers) as! JSONstandard
// print(readableJSON)

if let posts = readableJSON["posts"] as? [JSONstandard] {
for post in posts {
let title = post["title"] as! String

let author = post["author"] as! String

guard let dic = post["summary"] as? [String: Any], let summary = dic["value"] as? String else {


if let imageUrl = post["image"] as? String {
let mainImageURL = URL(string: imageUrl )
let mainImageData = NSData(contentsOf: mainImageURL!)
let mainImage = UIImage(data: mainImageData as! Data)

postsinput.append(postinput.init(mainImage: mainImage, name: title, author: author, summary: summary))
DispatchQueue.main.async {


catch {


override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return postsinput.count

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")

// cell?.textLabel?.text = titles[indexPath.row]

let mainImageView = cell?.viewWithTag(2) as! UIImageView

mainImageView.image = postsinput[indexPath.row].mainImage

//(cell?.viewWithTag(2) as! UIImageView).image = postsinput[indexPath.row].mainImage

let mainLabel = cell?.viewWithTag(1) as! UILabel

mainLabel.text = postsinput[indexPath.row].name

mainLabel.font = UIFont(name: "Helvetica", size:14)

let autLabel = cell?.viewWithTag(3) as! UILabel

autLabel.text = postsinput[indexPath.row].author

autLabel.font = UIFont(name: "Helvetica", size:12)

let sumLabel = cell?.viewWithTag(4) as! UILabel

sumLabel.text = postsinput[indexPath.row].summary

sumLabel.font = UIFont(name: "Helvetica", size:12)

//(cell?.viewWithTag(3) as! UILabel).text = postsinput[indexPath.row].author

return cell!

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

You can use this code for stripping html tags

From your previous question

guard let dic = post["summary"] as? [String: Any], let summary = dic["value"] as? String else {
let str = summary.replacingOccurrences(of: "<[^>]+>", with: "", options: .regularExpression, range: nil)


I have checked it and it is working

let summary = "<p>Latin text here</p>"
let str = summary.replacingOccurrences(of: "<[^>]+>", with: "", options: .regularExpression, range: nil)

Latin text here
