![]() ![]() The Mp3tag manual tells you about escaping special characters too.įor example, the square brackets have a special function within Mp3tag. The \d tells the RegEx machine, that there is a generic digit expected, not the character d. The dot and the square brackets are escaped to tell the RegEx machine, that these characters have to used literally and not as a RegEx command. Opening Square Bracket, Digit, Point, Digit, Closing Square Bracket Opening Square Bracket, Digit One, Point, Digit Two, Closing Square Bracket this is a sequence of literal characters. So if you want to detect this string by a Regular Expession. Escape all special characters which are reserved within Mp3tag by enclosing into a pair of Single Apostrophes.Escape all characters which have to be escaped for usage within a Regular Expression by prefixing one Backslash.You see that there are two stages of escaping to consider: '' -> '' to remove those timestamps.Īnd the only thing I missed before is that single quote enclosing the search string. If all works satisfying, then run your scripting work against your production files. Try out your scripting work with a test file. using an action "Format value".įormatstring: $regexp(%TEXT%,'(\n|^)(.+?)(\r|$)',$1$2$3)Īdapt the elaborated proposal to your needs. ![]() This removes all characters within the leading square brackets and the square brackets too at the beginning of each line. So only the usage of Regular Expression comes into mind, provided that the Regular Expression implementation within Mp3tag supports multi-line processing or at least placeholders for "CarriageReturn" and "LineFeed" characters.īecause the Mp3tag RegEx implementation allows the usage of \r \n placeholders, we can write such RegEx expression (there might exist other expressions, which will give the same result): This might be more complicated, because Mp3tag does not support repeated operations in one go on a tag field, will say, we cannot create a loop when processing one tag field content (there might be a possibility when exporting tag field content using the Mp3tag Export Scripting Language"). You want to manipulate multiple lines of text at once, which are stored in one tag field, previously read in from a text file. ![]() If your problem would be such simple, then you have now all tools at hand to solve it.īut you want to do text processing with more than one line of text. This splits the incoming string into parts, detects the part which is indicated by the round brackets, then returns the value by the $1 referer. Using Regular Expression function $regexp() This skips the first 10 characters and returns the remaining characters starting at position 11. If the timestamp has always the length of 10 characters, you can use an expression: Using simple scripting functions $len(), $sub(), $mid(). The textline is stored in a tag field "TEXT". The following two examples are restricted to a single line only. Mp3tag supports different tools to solve such approaches. Others may ask: "How can I remove the leading part, which is enclosed in square brackets." Some people ask: "How can I remove 10 characters from the left side of the string". You ask: "How can I remove the lyrics timestamp". You want to remove some characters from a text line: Your examples from above demontrate that you did not learn how to drive your car and how to understand the meaning of the signs in the street, but anyway you are driving the car. To avoid collisions with the Mp3tag scripting language, a regular expression sometimes need 'escaping' of special characters. square brackets, single apostroph, double apostroph, percent sign (documented in the Mp3tag manual).įurther more there are special restrictions when using the Regular Expression functionality.Ī regular expression can be seen as a 'scripting language' for it's own. If you are working with Mp3tag scripting language, then take into account, that special characters from the character set are reserved for special tasks, e. If you need further informations about general usage of computer or programming knowledge, which has nothing to do with Mp3tag in depth, then browse the internet to find an answer. While reading the Mp3tag manual, let you be guided by the offered syntax descriptions for using this or that function. ![]() Read user questions and answers to learn from other people's examples. Read the Mp3tag manual before you try to solve a problem, that is new for you. Freekey, it looks like that you spend much time to try out things, which will not work per se. ![]()
