How can I traverse HTML DOM with Swift

Question

I have an http POST response which I receive in HTML. Now I want to display the results in my view Controller. How can I parse the DOM of the response to get the elements I want?

This is the response in raw html:

I'm currently trying to use HTMLKit based on a couple tutorials, but I can't truly traverse the DOM with this library. Any ideas?

You can try SwiftSoup library that allows HTML parsing.

Usage

do {
    let html: String = "An example link.";
    let doc: Document = try SwiftSoup.parse(html)
    let link: Element = try doc.select("a").first()!
    
    let text: String = try doc.body()!.text(); // "An example link"
    let linkHref: String = try link.attr("href"); // "http://example.com/"
    let linkText: String = try link.text(); // "example""
    
    let linkOuterH: String = try link.outerHtml(); // "example"
    let linkInnerH: String = try link.html(); // "example"
} catch Exception.Error(let type, let message) {
    print(message)
} catch {
    print("error")
}
