Error - Get text for XML and cause error "NullreferenceException: Object reference not set to....."

Hello Everybody!

My name is Ares and i tryng creat an app, but have a problem... Before testing, get one exception:
NullReferenceException: Object reference not set to an instance of an object.

Im using unity 5.6 and EasyAr for my project.


When starting the program, it brings all the information from the server, however after this it generates this error and hangs. I added a validation in the "GetText" to just know if it has information and the label is filled normally, but the error persists.

My Code:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using System.Xml;
7. using System.Text;
8.  
9.  
10. public class texto_Aries : MonoBehaviour {
11.  
12.     public Text myText;
13.  
14.     // Use this for initialization
15.     void Start () {
16.     }
17.  
18.     // Update is called once per frame
19.     void Update() {
20.  
21.         if (getText() != null) {
22.             string hoscopo = getText();
23.             myText.text = hoscopo;
24.         } else {
25.             myText.text = "Consultando os astros! Em breve teremos informações para você!";
26.         }
27.     }
28.  
29.     public string getText()
30.     {
31.         XmlDocument rssXmlDoc = new XmlDocument();
32.         string descricao = "";
33.  
34.         rssXmlDoc.Load("http://www.bemdesaude.com/rss/horoscope/aries.html");
35.  
36.         // Parse the Items in the RSS file
37.         XmlNodeList rssNodes = rssXmlDoc.SelectNodes("rss/channel/item");
38.  
39.         StringBuilder rssContent = new StringBuilder();
40.  
41.         // Iterate through the items in the RSS file
42.         foreach (XmlNode rssNode in rssNodes)
43.         {
44.             XmlNode rssSubNode = rssNode.SelectSingleNode("description");
45.             descricao = rssSubNode != null ? rssSubNode.InnerText : "";
46.         }
47.  
48.         return descricao;
49.     }
50. }

Help me please!

 

Well, first off, doing this in Update is not a good idea. You're hitting your server once a frame by doing this. I doubt that is what you want or even need to do.

Otherwise, if you're getting null, check where it's failing with debug.log statements to print out values.

 

really is not the goal. However, in Start also the problem persists. I tested this method in visual studio and it worked normally, I can not get the null object.

 

I am trying to instantiate the Text class. When debugging, I noticed that the "myText.text" is null. But it's not working ...

Code (CSharp):

1.     void Start () {
2.             myText =  GetComponent<UnityEngine.UI.Text>();
3.            
4.             if (!string.IsNullOrEmpty(getText())) {
5.                 horoscopo = getText();
6.                 myText.text = horoscopo;
7.             }
8.        
9.     }
