Saving Cell Contents To XML File Saved As Current Workbook File Name

I have numerous spreadsheets that I need to open and unhide a sheet, that has XML data stored in cell A1. What I need to do is copy that data in cell A1 and paste it into a text document and save that as an XML file saved as the XLS workbook name with a date stamp.

I'm running into many issues, the main issue is the saving as current file name, and the formatting of the text/XML file.

Here is my current code, which doesn't reference the current file name and is just very generic. Once I get the saving as file-name correct and the formatting of the xml file correct, I will work on it a bit more.

Code:
Sub Test()
Dim Rng As Range
Dim wb As Workbook
Set Rng = Range("A1:A2")
Set wb = Workbooks.Add
With wb
Rng.Copy
