Separation of multiple languages in one document

Hello,

I would like to set up a workflow for classifiying patent documents as relevant/not relevant regarding certain technologies or processes. Basis for the classification should be the set of claims. In many documents (especially european patents), the claims appear in more than one language, mostly English, German and French, at the same time in one document. My question is: Is it possible to separate for example the german, english and french text blocks from each other so that hey could be furtherly processed by a separate workflow branch or s separate workflow ?

Kind regards

Michael
