But I do not get such errors when I am trying to compile all with dmd:
dmd findlinks.d dhtmlparser.d quoteescaper.d

it's produce proper exe file.

If suggest, that I created proper dub.json file, how I can use it.

Now I have small app named find_links.d I put it in new dub project. And what next? How to link it's with DHTMLParser?
