Filter for all titles with words in lower case

[wab66]

Hey,

I already looked through the FAQ but couldn't find a solution for this filter query.

I'm looking for a filter too display only titles which contain at leat one word in lower case.

Any thoughts?

Thx

\b\l+\b

Hey Dano,
this seems to be quit good but unfortunatelly I still have a few results which seem to belong
to the ' which is interpreted as a space so that the rest is interpreted a lower case word .

Examples:

Non C'e
I'll Follow The Sun
C'mon People

And could you explain the structure with a few words

Thx for the fast response.

\b is a word boundary.
Here is a definition of it:

There are four different positions that qualify as word boundaries:

*  Before the first character in the string, if the first character is a word character.
* After the last character in the string, if the last character is a word character.
* Between a word character and a non-word character following right after the word character.
* Between a non-word character and a word character following right after the non-word character.

\l simple stands for a lower character.

If you don't want that ' is a word boundary you must define your own:
(^| )\l+\b
That would be a simple example that says that a word can start either if it is the first character or if there is a space before it.

Hey Dano,
thanks, that works perfectly for a first approach to find german songs (which usally contain Umlaute or/and lower case words in title or artist).
Than I can tag them easily.

Do you have a link for the other options and their explanation. Right now I worked with the script options for retagging.

Thanks once more for this super fast solution.

What do you mean by options?

I came across this thread as I am trying to do the same thing: filter for any lowercase words in the title. However, I'm not sure how to use "\b\l+\b". Would it be something like this?

%_title% HAS \b\l+\b

• OR -

%_title% MATCHES \b\l+\b

I've looked over the help files and tried a bunch of different combinations but can't figure out how to get this to work.

Any help would be most appreciated. Thanks!

... filter for any lowercase words in the title.

Mp3tag has in the filter section a preset to ignore case, therefore the regular expression for MATCHES has to be set to switch off ignore case in order to respect case.

TITLE MATCHES "(?-i)\b\l+\b"

Thank you for the explanation!
I ran into the same issue as Wolfgang B, needing to exclude ' as a word boundary.

I added dano's bit to the expression, which appears to do what I need:

TITLE MATCHES "(?-i)(^| )\b\l+\b"

However, even though this works, is it "correct"?

Thanks again!
