Eclipse provides a mechanism to programmatically identify file types based on their actual content. The org. eclipse. core. contenttype. contentTypes extension point can be used to define a content type described by a "describer," which is a class capable of recognizing specific types of content given an input stream. Editors designed to work with a specific content type can be bound to it instead of a file extension.

We need to specify the content type in the plugin.xml like below

<extension point="org.eclipse.core.contenttype.contentTypes">
<content-type base-type="org.eclipse.core.runtime.xml"
             file-extensions="xml"
             id="ca.ecliptical.examples.contenttype.apples"
             name="Apples File"
             priority="normal">
  <describer class="org.eclipse.core.runtime.content
                    .XMLRootElementContentDescriber">
     <parameter name="element"
                value="apples">
     </parameter>
  </describer>
</content-type>

below is the references and it works fine

Check the file's Open With context menu, and the defaults on the File Associations preference page.
