How to get the SiteMap object from a configuration in hst:hst/hst:configurations programmatically?

Hi!

We are interested in getting the Sitemap object programmatically for a given configuration in our hst:hst/hst:configurations node.

Is it possible to get this object knowing the id of the configuration node that contains the sitemap?

To illustrate this requirement, see the image below

So, knowing the name of the configuration node (common_en), get the Sitemap object contained in it programmatically, if possible, at valve level.

Thanks in advance.
