次の文字列があります。

"Sweden, Västmanland, Västerås" 
"Sweden, Dalarna, Leksand" 
"Ireland, Cork, Cobh"
"Ireland, Clare, Boston"
"Ireland, Cork, Baltimore"
"Sweden, Dalarna, Mora"

次のようにxmlに変換したい：

<?xml version="1.0" ?> 
<data>
<country name = "Ireland">
    <region name = "Clare">
        <settlement name  = "Boston"/>
    </region>
    <region name = "Cork">
        <settlement name = "Baltimore"/>
        <settlement name = "Cobh"/>
    </region>
</country>

<country name = "Sweden">
    <region name = "Dalarna">
        <settlement name = "Leksand"/>
        <settlement name = "Mora"/>
    </region>
    <region name = "Västmanland">
        <settlement name = "Västerås"/>
    </region>
</country>
</data>

不必要に車輪を再発明するために、この変換を行うのに役立つpython3の組み込みライブラリは何ですか?
