xml to json to jsonp converter

Does such a converter exist?

For example, I want to convert the following:

http://w开发者_如何学Pythonww.bbc.co.uk/travelnews/tpeg/cy/regions/rtm/wales_rss.xml

to pure jsonp.

Something like this query using YQL ?

select * from xml where url='http://www.bbc.co.uk/travelnews/tpeg/cy/regions/rtm/wales_rss.xml'

XSLT can be used to convert from XML to JSON. From there it's trivial to convert to JSONP.

if it's just a one time conversion you could use:
