I need only content details from my code

Hi,

See collected the Master page text content details from below code using Indesign javascript:

if(master[i].textFrames[j].parentPage != null)

{

      contents +="\""+ master[i].name + "\",\"" + master[i].textFrames[j].contents + "\"\r";

}

If my contents is empty in my master page(for instance B-Master page), I don't need that details from above code, I need only contents on Master page detail only, anybody can help me for new code. FYI I don't need the highlighted details in below snapshot.
