Now this list is pretty long. What you want to do is to check out just the albums with the most number of votes. So how can txtproc help you achieve this?

First, you need to make this list available to txtproc for processing. The easiest way to do this is to select the list in your browser and copy it to the clipboard (with Ctrl + C).

We use the following three processing functions for the final result:

1. RemoveEmptyLines to make the list more compact
2. ReplaceRegex to remove the release dates (because they interfere with step 3)
3. SortLinesByNumber to sort the list by first number found on each line

The three steps can be used in a pipeline like this:

on Linux:

xclip -o -selection c | ./txtproc -eremoveemptylines | ./txtproc -ereplaceregex -p"July \d+" -p" " | ./txtproc -esortlinebynumber

on Windows:

./txtproc -v -eremoveemptylines | ./txtproc -ereplaceregex -p"July \d+" -p" " | ./txtproc -esortlinebynumber

which results in:
