Calling an XML outside of unity

Questions & Answers
1

OK I know how to call and display xml file in unity from the asset list, but what do I need to change so that I can call from an xml that I just dump into the build folder so that I can edit it outside of unity without have to rebuild the project every time

Below is the ENTIRE project code it uses only one script at the moment
I want to call from an xml outside of unity

UPDATE–I have used the first answer to call the xml from outside the program by declaring the file path. But this is not enough as I need to call the file without knowing the exact location and if I could force the XML to build in the resource folder than part of the problem would be done

Is it possible to use a Application.datapath to call the XML without declaring an exact location?

Try using the StreamReader class from the System.IO namespace.
Here is the MSDN link

You would read the xml file from the path then use the text from the stream to load your xml
For example

    string path = "C:/myfolder/myproject/data.xml"
    
    StreamReader reader = new StreamReader(path)
    xmlDoc.LoadXml(reader.ReadToEnd())
    reader.Close()
