I currently use a piece of XML like the following

<Person>
    <Name>Frank Smith</Name>
    <Id>100023412</Id>
    <DOB>12/05/1954</DOB>
    <LasLogin>01/09/2010</LasLogin>
    <FavOS>Windows</FavOS>      // Wild card that may occasionally appear
</Person>

What I am stuck with, is when using XStream I need to be able to ignore certain tags that appear (in the case above 'FavOS') These tags may not be known or change in the future. Is there a way to Ignore all tags that do not match what is currently implemented?

(Using XStream 1.3.1)

java xstream
