XML update from different objects issue

Hi guys

I know that there are hundreds of threads talking about xml, how to load and save it, etc etc
I open this post just to ask if someone can help me with a little problem that I'm not sure how to fix

I have a scene where I read an xml file and update it using serialize method as I show:

Code (CSharp):

1. TextAsset textAsset = (TextAsset)Resources.Load(NameXml, typeof(TextAsset));
2.         SHOWPOIMANSION1 SPM1 = new SHOWPOIMANSION1 ();
3.         SPM1 = SPM1.Load (textAsset);
4.  
5.  
6.         if (obj.name == "POI_MesaDespacho_1") {
7.                         SPM1.ShowPOI_MesaDespacho_1.POI = 1;
8.                 } else {
9.                         SPM1.ShowPOI_CajaFuerte_1.POI = 1;
10.                 }
11.      
12.         var serializer = new XmlSerializer (typeof(SHOWPOIMANSION1));
13.         var stream = new FileStream (Application.dataPath + "/Resources/" + NameXml + ".xml", FileMode.Open);
14.  
15.         serializer.Serialize (stream, SPM1);
16.         stream.Close ();
17.  

SHOWPOIMANSION1 is a class defined with some elements, one of them is "ShowPOI_MesaDespacho_1" but there are more

My problem is that when I apply the same code for other element, doesn't keep the first change applied to xml file
Looks like if always load the first xml file that I loaded when I started to use it

Anyone know why append that? maybe I should close the file in some way or similar?
Problem is that don't update correctly objects, load first xml file that existed and always that write or update something, do that against the first xml load, not to the last update

any advise?

 

Resources.Load() loads an asset form an asset container and not from an folder.
That way you can not write the XML file at at run time. (This works in the editor but not the final game).
If you need to read and write an XML file , you should use the streamingAssets folder.

Thanks ffMalzbier

I have my xml file under Assets/Resources/ directly, that is where Resources.load() search for assets
That works properly so I'm not sure if that's the problem

I'm going to try that about streamingAssets

 

When you build your game , the files in the resources folder will be packaged into a container file called resources.assets . You can read with Resources.Load() but you can not write to it. streamingAssets will do what you are searching for. (You can't use Resources.Load() in that case)

 

StreamingAssets was final solution, thanks!!
