You won't be able to get anywhere close to this, for several reasons:
- tags can't start with a digit
- values can't be tags
- unless you override in XmlElement etc., tags will be derived from field
names
Maybe like this:
<myBean>
<entry>
<key>flower</key><valueList>rose lily</valueList>
</entry>
<entry>
<key>fruit</key><valueList>apple orange</valueList>
</entry>
</myBean>
