XML errors

Hi there,

XML file can’t open properly and shows this warning.

This page contains the following errors:
error on line 121274 at column 1: Extra content at the end of the document
Below is a rendering of the page up to the first error.

I have downloaded the file and check with editor. Problem is in last 4 lines. Like it is duplicated.
