What is the best way to strip out a changing segment of text from a string?

let: string str = 
"a=<random text>
 a=pattern:<random text (may be fixed length)>
 a=<random text>";

In the given string above, let's assume that a= and pattern are constants. It is possible that there may or may not be a line break (\n) after each line. Can you suggest a way to eliminate a=pattern:<random> from the string variable str?

Answer №1

To efficiently remove specific text, consider utilizing regex capturing groups to specify the content surrounding the text you wish to eliminate.

let updatedString = originalString.replace(/(start=.+(\n)?)(textToRemove:.+)((\n)?end=.+)/, "$1$4")
