SWXMLHash: how to build struct for very deep XML? - alamofire

Question

I am now working on a complex XML parsing.
Here is the link: https://www.reddit.com/hot/.rss
I use Alamofire to fetch data:
protocol APIUsable {
}
struct API: APIUsable {
static func fetchRedditFeedListData() -> Observable<[Entry]>{
let URL = "https://www.reddit.com/hot/.rss"
return Observable.create { observer in
Alamofire.request(URL).response { response in
guard let data = response.data else {
return
}
do {
let xml = SWXMLHash.parse(data)
let entries: [Entry] = try xml["feed"]["entry"].value()
observer.onNext(entries)
} catch let error as NSError {
print(error.localizedDescription)
}
observer.onCompleted()
}
return Disposables.create()
}
}
}
The following is the struct I build for parsing. And It works well.
struct Entry: XMLIndexerDeserializable {
let title: String
let updated: String
let category: String
let content: String
static func deserialize(_ node: XMLIndexer) throws -> Entry {
return try Entry(
title: node["title"].value(),
updated: node["updated"].value(),
category: node["category"].value(ofAttribute: "term"),
content: node["content"].value()
)
}
}
But I also want to get the image string belong to content, img, src

I have found the solution by myself.
As we can see that there is a HTML in a XML.
So, I use SWXMLHash again to parse content
let xml = SWXMLHash.parse(/*put the content String here*/)
let imageString = xml ["table"]["tr"]["td"][0]["a"]["img"].element?.attribute(by: "src")?.text
then we can get the value of src as string for future use
