How to generate RDF RML file from XML data?

I want to generate RML file From XML.
Input data in XML format
and output as RDF RML File.
Input:
<Events> ...
<Exhibition id="398">
<Venue>STAM</Venue>
<Location>
<lat>51.076891</lat>
<long>3.717222</long>
</Location>
</Exhibition> ...
</Events>

Output:

<#EventsMapping>
rml:logicalSource [
rml:source "http://ex.com/events.xml";
rml:referenceFormulation ql:XPath;
rml:iterator "/Events/Exhibition" ];

rr:subjectMap [
rr:template "http://ex.com/{@id}" ];

rr:predicateObjectMap [
rr:predicate ex:location;
rr:objectMap [
rr:parentTriplesMap <#LocationMapping> ] ].

give me your kind suggestions for generating RML file from XML data and if possible suggest in java for the library if available.
Also, Suggestions accepted.

Hi,
I have a common strategy for generating RDF from XML
- step one: I use XSLT for creating and RDF-XMLM version of the RDF
- step two: I use apache jena for different serialisations of the RDF XML

Hi, thanks for reply Geert Bormans. Before I am using the same way as you suggested but now in our functionality, we need to map with RML file then convert it to RDF so that I need to generate RML file first for mapping purpose. as you see in my example I need the same mapping file from XML input.
