Need To Convert An XML File Into Something Readable

[SonicBrewtality]

A friend of mine has downloaded some texts from his mobile because he needs proof of something for a court case, this means dates of the texts are needed. It's downloaded as an xml file but it comes up as a bunch of code. The only really readable thing are the texts themselves but the dates are just a string of numbers now. Is there anything that can make this readable?

Here's a screen of the file opened in Internet Explorer

Try opening it with Microsoft Excel.
