Consider adding the metadata for navigation, if not there already, as nodes.
Then, you can use XPath to prune out the nodes you want. For example:

<SideMenu>
    <LinkName>Policies</LinkName>
    <LinkURL>policies.aspx</LinkURL>
    <Section>Home</Section>
</SideMenu>

NOTE: The XML here is DataSet style, but the principle is still the same.

With XPATH, you can set up a query that only finds those side menu items
that are in section Home. The reason I use DataSet XML for menus is we are
aiming for eventually moving the menus to a database, with an admin utility
for all of our applications. By starting with XML that is DataSet oriented,
I can easily change to the database, when finished, without rewriting the
bind.
