I have multiple .opml files (that list rss feeds I subscribe to in xml i.g.) with different contents on different devices. How can I merge them without duplicates? Are there tools for this?
You must log in or # to comment.
If still needed, I have some ideas though only partially automated.
If I remember correctly, OPML files’ syntax is pretty straight forward so you could merge them manually.
If feeds are divided in groups, you probably need to merge per group.
With a text editor that has both line sorting and regex replacing functions (e.g. Sublime Text), select each the range to be sorted and sort them one selection at a time (F9 on Sublime Text), then with regex, replace
^(.*)(\r?\n\1)+$for\1(remember to activate regex search if needed).And explaining the regex, I can’t remember how I got to that, but it finds lines that appear immediately after the ones they repeat and replace for the first case of the repeated lines. However, if line 1 is repeated on line 50, as an example, and all lines between them are miscellaneous ones, the regex won’t pick them.
