Need a CS6-InDesign-Macro that changes the appliedLanguage of some text elements

Attached please find a page in indd. This page has many text-elements. They are in Layers. I need a script that - changes the appliedLanguage in each text-element inside the Layer "Deutsch" to "German: 2006 Reform" ("de_DE_2006") - changes the appliedLanguage in each text-element inside the Layer "Französisch" to "French" ("French") - changes the appliedLanguage in each text-element inside the Layer "Englisch" to "English: UK" ("English: UK") - changes the appliedLanguage in each text-element inside the Layer "Russisch" to "Russian" ("IDX_Russian") Attached is a screenshot so you see how the layers render. Please be aware we dont need the correct page. We need an CS6-InDesign-Macro-script (!) that makes the changes.
