XML Online Parsing C Sharp

Unity Engine
1

Hi guys,

I’m trying to make a form to fill in in a Unity project that collects and sends data to a XML document online.

I managed to make a successful local file that saves absolutely fine, but once I try to hook it up to the internet I get an error and I’m not sure what’s going on. Can someone explain where I’m going wrong?

WORKING LOCAL VERSION

public void NameAndEmail()
	{
		string filepath = Application.dataPath + @"/DataSharing/CustomerData.xml";
		
		XmlDocument xmlDoc = new XmlDocument();
		
		if(File.Exists (filepath))
		{	
			xmlDoc.Load(filepath);
			
			XmlElement elmRoot = xmlDoc.DocumentElement;
			
			elmRoot.RemoveAll();
			// To refresh document.. Only for testing purposes.
			
			XmlNodeList iEmployees = xmlDoc.GetElementsByTagName("Name");
			int iNoEmployees = iEmployees.Count;
			
			XmlElement employee = xmlDoc.CreateElement("Employee_No_" + iNoEmployees.ToString() ); 
			
			if( !PlayerPrefs.HasKey("EmployeeNumber") )
			{
				PlayerPrefs.SetString("EmployeeNumber", "Employee_No_" + iNoEmployees.ToString());
			}
			else
			{
				employee = xmlDoc.CreateElement( PlayerPrefs.GetString("EmployeeNumber") );
			}
			
			
			XmlElement employeeName = xmlDoc.CreateElement("Name");
			employeeName.InnerText = sName;
			
			XmlElement employeeEmail = xmlDoc.CreateElement("Email");
			employeeEmail.InnerText = sEmail;
			
			employee.AppendChild(employeeName);
			employee.AppendChild(employeeEmail);
			elmRoot.AppendChild(employee);
			
			xmlDoc.Save(filepath); // save file.
		}
		else
		{
			Debug.Log("XML Document Not Loaded Correctly");
		}
		
		LoadGame();
	}

NOT WORKING ONLINE VERSION

IEnumerator NameAndEmail()
	{
		string url = "http://www.nigelclark.com/test/blank.xml";
		WWW www = new WWW(url);

		yield return www;

		//XmlDocument xmlDoc = new XmlDocument();
		
		if(www.error == null) 
		{	
			string xml = www.text;
			XmlDocument xmlDoc = new XmlDocument(); 
			
			xmlDoc.LoadXml(xml); 
			
			XmlElement elmRoot = xmlDoc.DocumentElement;
			
			//elmRoot.RemoveAll();
			// To refresh document.. Only for testing purposes.
			
			XmlNodeList iEmployees = xmlDoc.GetElementsByTagName("Name");
			int iNoEmployees = iEmployees.Count;

			Debug.Log(iNoEmployees);
			
			XmlElement employee = xmlDoc.CreateElement("Employee_No_" + iNoEmployees.ToString() ); 
			
			if( !PlayerPrefs.HasKey("EmployeeNumber") )
			{
				PlayerPrefs.SetString("EmployeeNumber", "Employee_No_" + iNoEmployees.ToString());
			}
			else
			{
				employee = xmlDoc.CreateElement( PlayerPrefs.GetString("EmployeeNumber") ); 
			}
			
			
			XmlElement employeeName = xmlDoc.CreateElement("Name");
			employeeName.InnerText = sName;
			
			XmlElement employeeEmail = xmlDoc.CreateElement("Email");
			employeeEmail.InnerText = sEmail;
			
			employee.AppendChild(employeeName);
			employee.AppendChild(employeeEmail);
			elmRoot.AppendChild(employee);
			
			xmlDoc.LoadXml(xml); 
			//xmlDoc.Save(xml);
			//xmlDoc.Save(filepath); // save file.
		}
		else
		{
			Debug.Log("XML Document Not Loaded Correctly");
		}
		
		LoadGame();

		yield return null;
	}

I’m getting this error:

XmlException: Document element did not appear.  Line 1, position 1.
Mono.Xml2.XmlTextReader.Read ()

System.Xml.XmlDocument.ReadNodeCore (System.Xml.XmlReader reader)

XMLInformation+<NameAndEmail>c__Iterator7.MoveNext () (at Assets/Code/XMLInformation.cs:82)

But I’m not sure what I’m actually doing wrong?

Can anyone help?

Thanks!
