Can I mark an XML element as untranslatable based on its attribute?

My client sent me an XML file containing multiple languages. Each language is stored in the same element, but the language is contained in the attribute.

I only have to translate the English strings. Can I create a parser rule in SDL Trados Studio 2017 that can do that?
