index.xml does not act as the default entry for apache?

I need to config my Apache server that shows the content of a index.xml file like a index.html without the need to put it(index.xml) at the end of the URL like this:

http://localhost/xml/details/13986

instead of

MEDevel.com: Open-source for Healthcare and Education

Collecting and validating open-source software for healthcare, education, enterprise, development, medical imaging, medical records, and digital pathology.

Visit Medevel

http://localhost/xml/details/13986/index.xml

Currently, if I remove the index.xml from the URL it shows the files list of that folder in the browser and I need to add index.xml to the end of the URL to get the content.

Note: I need this because some old code using this URL without index.xml and I can’t change it. For some reason, it doesn’t work for me on my computer and I need to add this to the URL to get the content.

Do you have any idea about this config?

>Solution :

Change the configuration in apache2.conf

DirectoryIndex index.html instead of DirectoryIndex index.php

and restart you apache
