Php version to run the script and convertible file location

[inessaah]

Hello!
I've been trying to use your script with php 7.1.7 and got an error message

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Markdownify has a deprecated constructor in C:\distr\testrail-migrate-testlink-1.9\testrail-migrate-testlink\lib\markdownify\markdownify.php on line 58

So, please, tell in which version of php script will work or tell what do i havу to fix in it.
Also i've got a problem with location of convertible file - where should it be located. I've put it in the directory where script is, but got an error message

File 1.xml not found

You need PHP 5.x.
