How to add xml to project build

How do you load xml file? From WWW class or you create script and it create public TextAsset variable?

I load it using System.X$$anonymous$$L; libraries:

 var serializer = new XmlSerializer (typeof(TranslationsContainer));
                         var stream = new FileStream ((Application.dataPath + PATH), File$$anonymous$$ode.Open);
                         TranslationsContainer container = serializer.Deserialize (stream) as TranslationsContainer;
                         stream.Close ();

I found in this article that there is no physical text file included to the build in any case. In my game was a problem to load xml, thats why I thought that file was not included. I unpacked apk and didn't find there my xml, and tried to include xml. Now I will try another way to resolve my problem.
