How to transform nested dictionaries into xml structure?

Say, I have the following data structure:

data = {'cheese': 
   [{'url': 'url a', 'phone': 'phone a', 'products': ['butter', 'cheese'], 'name': 'name a'}],
       'butter': 
   [{'url': 'url b', 'phone': 'phone b', 'products': ['butter'], 'name': 'name b'}, {'url': 'url a', 'phone': 'phone a', 'products': ['butter', 'cheese'], 'name': 'name a'}]}

And I want to create the following xml-file based on it:

xmlTemplate = """<root>
    <product>
        <type>cheese</type>
        <consumer>
            <url>url a</url>
            <phone>phone a</phone>
        </consumer>

        <type>butter</type>
        <consumer>
            <url>url a</url>
            <phone>phone a</phone>
        </consumer>
        <consumer>
            <url>url b</url>
            <phone>phone b</phone>
        </consumer>

    </product>
</root>"""

I tried to use string formatting to create such xml, but I could not figure out because of nested list and dictionary. Does anybody know how to do this? Or maybe it's better to use some other method?
