I am using a calibre recipe (Weltonline; german daily newspaper) to fetch news daily. Everything works fine, but in the final epub file after every news article there is plenty of (web-) rubbish I want to get rid of. Therefore I use Sigil and work on the epub I have downloaded from my calibre server. I delete everything between two string groups:
( <div class="calibre7">

Now I have seen that there is a way to preprocess regex expressions while fetching the news with calibre. But I have also seen that python requires a slightly different approach towards regex and I am no expert in different regex dialects nor am I a python programmer.Took me quite a while to figure out the regex above
Could someone tell me how to use the above regex in the forementioned recipe in a way to use this preprocessing?
