What are these textnode?

I am using jQuery to get all strings on my web page, I use the following code but gets a lot of objects, it does not make sense because there are only 20 strings on my page, after looking into details, I found strange elements are also treated as textnode, please see screenshot attached, do you know how i can get rid of them?

jQuery(":not(:empty):visible()").contents().filter(function(){return this.nodeType===3})
