Hello Everyone, A.] The objective is to set up a filter, which is applicable to file names. The filter should find the file names in which the track number matches the following numbering style: 101 206. 710. 911. — Three numerals followed by a dot, all of which are located at the very beginni…

[image] ragtag: Three numerals followed by a dot try: %_filename% MATCHES "^\d\d\d\." the \d stands for a digit - and 3 of them for 3 digits. So, to filter for [image] ragtag: 1-15 Try: %_filename% MATCHES "^\d-\d\d\." or %_filename% MATCHES "^\d+-\d+\." and you can join them: …

For those asking what the ^\d+- means: [image] A digit ("number") that exists at least once or unlimited times, followed by a - in the first occurence and followed by a . ("dot") for the second occurence. The dot is a special character in regular expressions and has to be escaped with a \.

Thank you very much to you both, @ohrenkino and @LyricsLover . Especially also, to both of you for adding the explanations in there, too. I am beginning to recognise some of the patterns now.

I would like to revisit this topic with a question (or two): %_filename% MATCHES "^\d\d\d."` the \d stands for a digit - and 3 of them for 3 digits. Since the "^\d\d\d." indicates 3 digits, what does the filter-syntax for "any number" of digits look like? Something like this, maybe?: \d*\ W…

[image] ragtag: parenthesis around the filter-syntax [image] ragtag: `\d* would be "any number, including no number at all". If there should be at least 1 digit: \d+ AFAIK there is no special purpose for parenthesis in the filter regular expressions. I wonder where you found that.

would be "any number, including no number at all". If there should be at least 1 digit: \d+ Thank you very much, @ohrenkino AFAIK there is no special purpose for parenthesis in the filter regular expressions. I wonder where you found that. My question concerning the parenthesis arose from …

The ^ and $ sign are also special characters in regular expressions. The ^ means at position "Start of line" The $ means at position "End of line" "Line" in our case is the content of a tag or a filename for example. Please have a look at the documentation: [image] Regular Expressions –…

[image] ragtag: Could you please confirm whether parenthesis are to be used whenever an regular expression operator, such as one of the following, are deployed: No, the parenthesis are there to "collect/remember" the matched digits or characters. For example, if you want to replace the match…

[image] ragtag: For instance example, in the album field, I want to find anywhere in the description, the words: (CD(followed by any number)^ If you really want to search for opening bracket ( CD opening bracket ( any number, including no number at all closing bracket ) it would be som…

Thank you, @LyricsLover I have much to work with. My problem stems from using the caret "^", the regex special character, as part of the album name for multi-disc albums, for example: Album name A (CD3^6) Album name B (CD07^16) Therefore, the caret is part of the field description, and part of t…

[image] ragtag: Therefore, the caret is part of the field description, and part of the expression Ahh, I see. If you search for a text or number which has to be mandatory at the start position or at the end position, you have to use the ^ as very first character in your regular expression an…
