[jQuery] Filter xml

[kwilder]

Hi, I have this:

<Root>
        <Item RecurranceInterval="1" Type="Month" Name="Beginner"></Item>
        <Item RecurranceInterval="12" Type="Month" Name="Beginner"></Item>
        <Item RecurranceInterval="1" Type="Month" Name="Intermediate"></Item>
        <Item RecurranceInterval="12" Type="Month" Name="Intermediate"></
Item>
        <Item RecurranceInterval="1" Type="Month" Name="Advanced"></Item>
        <Item RecurranceInterval="12" Type="Month" Name="Advanced"></Item>
        <Item RecurranceInterval="1" Type="Month" Name="Pro"></Item>
        <Item RecurranceInterval="12" Type="Month" Name="Pro"></Item>
</Root>

I want to return, let's say, the entire set where the
RecurranceInterval equals "12", like this:

<Root>
        <Item RecurranceInterval="12" Type="Month" Name="Beginner"></Item>
        <Item RecurranceInterval="12" Type="Month" Name="Intermediate"></
Item>
        <Item RecurranceInterval="12" Type="Month" Name="Advanced"></Item>
        <Item RecurranceInterval="12" Type="Month" Name="Pro"></Item>
</Root>

I've tried the filter method, but I can't get it to work.  Any help
would be appreciated.

Thanks.
