Question

我在Swift中遇到XML解析问题。我想使用AttributeDict，但我有很多属性可以使用它。所以我使用Dictionary。但它不起作用，我在这个页面中使用代码：

Get attibuteDict of a subclass Xml parsing - Swift

但它仍然无效。如果你知道，告诉我我的XML数据：

 <root>
        <day1><day1 p1.1="-" pk1.1="-" s1.1="" a1.1="-" p1.2="-" pk1.2="-" s1.2="" a1.2="-"

我的工作代码：

@IBOutlet weak var tableView: UITableView!

func parser = NSXMLParser()
var schedule = NSDictionary()
var elements = NSMutableDictionary()
var element = NSString()

func beginParsing()
{
   parser = NSXMLParser(contentsOfURL: NSURL(string: "SomeUrl")!)! 
   parser.delegate = self
   parser.parse()
}

func parser(parser: NSXMLParser!, didStartElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!, attributes attributeDict: [NSObject : AnyObject]!)
{
   element = elementName
   if (elementName as NSString).isEqualToString("day1")
   {
       //name of subject
       schedule = [p1.1="-", pk1.1="", s1.1="", a1.1="", p1.2="", pk1.2="",
       s1.2="", a1.2="", p1.3="",  pk1.3="", s1.3="", 
       a1.3="", p1.4="", pk1.4="", 
       s1.4="", a1.4="", p1.5="", pk1.5="", s1.5="", 
       a1.5="", p1.6="", pk1.6="", s1.6="", a1.6="", 
       p1.7="", pk1.7="", s1.7="", a1.7="", p1.8="", 
       pk1.8="", s1.8="", a1.8="", p1.9="", 
       pk1.9="", s1.9="", a1.9="", p1.10="", pk1.10="", 
       s1.10="", a1.10=""]

       elements = NSMutableDictionary()
       elements = [:]

  }
}

func parser(parser: NSXMLParser!, foundCharacters string: NSString!)
{
   if element.isEqualToString("day1") {
   func parser(parser: NSXMLParser!, didStartElement elementName: String!, namespaceURI: String!, qualifiedName: String!, attributes: [NSObject : AnyObject]!) {

           element = elementName
           if (elementName as NSString).isEqual("day1") {

           }
       }
   }
} 


func parser(parser: NSXMLParser!, didEndElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!)
{
   if (elementName as NSString).isEqualToString("day1") {
      print(schedule)
   }`

我不创建这个XML数据，这个XML数据给了我我的大学

有几点意见：

您的didStartElement应该只看attributeDict以获取元素的属性。
在这种情况下，您不需要foundCharacters方法，因为您只解析元素标记，而不解析open和close标记之间的任何内容。
如果您需要foundCharacters方法，则不应在其中实施私有didStartElement。
您的示例中唯一的技巧是您使用嵌套的day1标记非常混乱XML。我真的建议将XML改为有意义的东西。

但是，如果你坚持这一点，一个相当灵活的解决方案是保留一堆元素名称（实现为简单数组，elementNames），将elementName推送到didStartElement的堆栈中{1}}（通过添加到elementNames数组的末尾）并在didEndElement中弹出一个（通过调用removeLast）。因此，例如，当您点击XML中的内部day1标记时，elementNames的数组将为["root", "day1", "day1"]。

现在，您可以通过查看day1中的最后两项是否{{1}来查看是否在查看另一个day1内的elementNames day1 }。

例如：

func beginParsing(URL: NSURL) {
    let parser = NSXMLParser(contentsOfURL: URL)!
    parser.delegate = self
    parser.parse()
    print(schedule)
}

var schedule: [String: String]?
var elementNames = [String]()

func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String]) {
    elementNames.append(elementName)
    let count = elementNames.count

    if count >= 2 && elementNames[count - 2] == "day1" && elementNames[count - 1] == "day1" {
        schedule = attributeDict
    }
}

func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {
    elementNames.removeLast()
}

func parser(parser: NSXMLParser, parseErrorOccurred parseError: NSError) {
    print(parseError)
}

Use this class for Parse XML data with the help of SWXMLHash xml parser in Swift language.

https://github.com/drmohundro/SWXMLHash


import UIKit

public struct ParseMyXMLApis {

    //MARK:- Parsing API here
    public static func getparseMyApi(input: String, action:String, completion: (result: String, error: NSError?) -> Void) {

        //Main API here
        let is_URL: String = "Enter your url here"

        let lobj_Request = NSMutableURLRequest(URL: NSURL(string: is_URL)!)
        let session = NSURLSession.sharedSession()

        lobj_Request.HTTPMethod = "POST"
        lobj_Request.HTTPBody = input.dataUsingEncoding(NSUTF8StringEncoding)
        //lobj_Request.addValue("www.cgsapi.com", forHTTPHeaderField: "Host")
        lobj_Request.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
        lobj_Request.addValue(String(input.characters.count), forHTTPHeaderField: "Content-Length")
        lobj_Request.addValue("http://tempuri.org/IService/\(action)", forHTTPHeaderField: "SOAPAction")

        let task = session.dataTaskWithRequest(lobj_Request, completionHandler: {(data: NSData?, response: NSURLResponse?, error: NSError?) -> Void in
            print("Response: \(response)")

            // Checking here Response
        if response != nil {

            let statusCode = (response as! NSHTTPURLResponse).statusCode
            print("Success: \(statusCode)")

            // Checking here Response Status
        if statusCode == 200 {
            //Handling Data here
            if data?.length > 0 {
            let strData = NSString(data: data!, encoding: NSUTF8StringEncoding)
            let xmls = SWXMLHash.parse(data!)
            func enumerate(indexer: XMLIndexer, level: Int) {
                for child in indexer.children {
                    let name:String? = child.element!.name
                    print("\(level) \(name)")
                    let text = child.element!.text
                    if text?.isEmpty == false{
                        print(text)
                        // Finish here Process
                        completion(result: text!, error: nil)
                    }
                    enumerate(child, level: level + 1)
                }

             }
             enumerate(xmls, level: 0)

            }else{
                //Data nil Condition here
                completion(result:"", error:error)
            }

            //Handling Error here
            if error != nil
            {
                print("Error: " + error!.description)
                completion(result:"", error:error)
            }

          }else{
                //Invalid Status
                print("Error: " + error!.description)
                completion(result:"", error:error)
            }

         }else{
            //Response Nil then handle here
            print("Error: " + error!.description)
            completion(result:"", error:error)
         }

        })
        task.resume()
    }

    //MARK:- String To Dictionary Conversion
    public func convertStringToDictionary(text: String) -> AnyObject! {
        if let data = text.dataUsingEncoding(NSUTF8StringEncoding) {
            do{
                let json:AnyObject = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions(rawValue: 0))
                return json
            }catch{
                print(error)
            }
        }
        return nil
    }

}

并调用此类

ParseMyXMLApis.getparseMyApi("Request here", action:"URL here", completion: { (result, error) -> Void in
                if error != nil{
                    //Handel Error here
                           }else{
                    print("Result is here\(result)")
                     }
        else
        {
            //Network Error Handling here
            print("Couldn't connect to network")
             }
      }
