unfold one element to several elements according to it

Hello everyone,
is it possible to do the translation? you can add other
elements/attributes in the original xml if the info is not enough.
thanks.

Original:
<product id="1" owner="a,b,c">
<title owner="a,b">foo</title>
<title owner="c">bar</title>
</product>

After translation:
<product id="1" owner="a">
<title>foo</title>
</product>
<product id="1" owner="b">
<title>foo</title>
</product>
<product id="1" owner="c">
<title>bar</title>
</product>
