Duplicate content produces fatal error / remove it

After this line (under everything as a comment), is duplicate content and produces several errors: 

---Error----

Warning: simplexml_load_file (): menu.xml: 89: parser error: Extra content at the end of the document in C: \ server \ data \ localweb \ Find \ functions.php on line 14 

Warning: simplexml_load_file (): ======= in C: \ server \ data \ localweb \ Find \ functions.php on line 14 

Warning: simplexml_load_file (): ^ in C: \ server \ data \ localweb \ Find \ functions.php on line 14 

Fatal error: Call to a member function children () on a non-object in C: \ server \ data \ localweb \ Find \ functions.php on line 15 

---Easy solution--

Because of these errors, the script does not work. The solution is to remove these extra lines (which are in the comments) and worked perfectly. 

Thanks John for your amazing work, and thanks for sharing it publicly. I really appreciate it, greetings, mau5datri@gmail.com
