Why do you need to restructure the xml? You can just keep the attributes. To add the salaries there are quite a few options, as XML is just as flexible as well.

Using a List (XSD List) type:

    <employees>
      <employee name="John Crichton" gender="male" salaries="10000 10000 1000" />
      <employee name="Aeryn Sun" gender="female" />
    </employees>

And using mixed content (complexType):

    <employees>
      <employee name="John Crichton" gender="male">
        <salary>10000</salary>
        <salary>10000</salary>
        <salary>10000</salary>
      </employee>
      <employee name="Aeryn Sun" gender="female" />
    </employees>
