Checked checkbox by keyword or class?

checked a checkbox by keyword? or maybe by class? I have many unordered items to place in other folders (file management over the web) Each element has a name and format, also each format has a class, let's see this image:

Here we see how the files are presented, as I mentioned earlier they have a name and format. It is also seen that each format is shown with a different class, those that are audio type, text type, tablets, etc.

HTML:

Let's see, I would like a script that runs through all the files, take part of the text and check it

For example, if I want to select all the elements that contain the keyword 'MacOS', then select all those that contain the word 'MacOS' or maybe its format. I have not seen anything like this either in additions or script.

I ask, can you create something like that?

If you can not create something like that, then I guess you could take your 'class' and automatically select all the matching ones

In summary: A script that only marks the '.rar' for example, among all the others-

I leave a DEMO on JSFiddle
