xQuery on returning maximum element

I am relatively new to xQuery. And I have been struggling to get a working solution for this. Basically i have the following xml:

<skills>
    <skill name="xQuery" level="2"/>,
    <skill name="R" level="1"/>,
    <skill name="Python" level="4"/>,
    <skill name="Python" level="5"/>,
    <skill name="Java" level="2"/>,
    <skill name="C" level="2"/>,
    <skill name="C" level="5"/>
</skills>

My expected resut is:
<skill name="XQuery" level="2"/>,
<skill name="Python" level="5"/>,
<skill name="R" level="1"/>,
<skill name="Java" level="2"/>,
<skill name="C" level="5"/>

For all elements with the same name, I would like to return the maximum value.
