Issue while converting from JSON to XML

When I am converting the below JSON to XML, it seems that __text property is being stripped off from the XML. 

{
    "root": {
        "number": {
            "__text": "1\n-\n222\n-\n500"
        }
    }
}

Can anyone tell how the __text property changes and what __text represents?

Below is a fiddle and library used

The __text property changes from the Javascript syntax of a multi-line string to the XML syntax of a multi-line string. This means that \n is converted to a newline.

1\n-\n222\n-\n500

will then become

1
-
222
-
500

which is the same, in different notation

Without knowing the library you're using, I'd guess that __text represents the content of the property you're describing.

Looking into the source of the library it seems like _ indicates an attribute and the attribute __text is a special attribute to indicate the text contained inside an XML element when the element also has attributes.

Here is an updated fiddle that should help you to understand this better: https://jsfiddle.net/gtLBx/924/

Here are the source code snippets, that imply the things I assumed:

  1. _ is an attribute, because of line 31:

    config.attributePrefix = config.attributePrefix || "_";

  2. _text is the name of an internal attribute, because of this line 272:

    result.__text = result.__text.join("\n");
