Yes, you can do it in a programmatic way. But that URL (/sitemap.xml),
even it's common used, it's not mandatory, so you can't use it as a
constant. But there is one way, not so direct, but at least one that is
standard:

1) From /robots.txt you can take the Sitemap's URL ("Sitemap:" as [1]
specifies)
2) According the extension proposed by DERI [2], you can check if the
sitemap points a SPARQL enpoint looking for the
sc:sparqlEndpointLocation element.

Hope that helps.

Best,
