Regular expression: match all content up to a certain word(s)

Question

Regular expression: match all content up to a certain word(s)

I have two different versions of a string that look like this:

The Student's Companion *Author: Alcock, Pete;May, Margaret;Wright, Sharon*MIL EAN/ISBN: 9781283333115

Java Programming: Java Expert*Author:Sarang, Poornachandra*MIL EAN/ISBN: 9781280117268

Now, I am trying to extract the first authors, which are Alcock, Pete and Saran, Poornachandra.

Currently, in Javascript, I am attempting the following:

var regex = new RegExp("(Author:)\\s(.+)(?=;|MIL)");
var regexVal = value.match(regex);
console.log(regexVal);

OR

var regex = new RegExp("(Author:)\\s(.+)(?=MIL)");
var regexVal = value.match(regex);
console.log(regexVal);

The second Regex functions well when there is only one author, however, if there are multiple authors, I need it to capture the value until the first ; not MIL

| should match either part, so shouldn't it stop at the first ;?

Best regards, Ravish

Here are some regular expressions you can use:

const pattern1 = /Name:\s([^\n]+)/;

If the string doesn't contain any asterisks:

const pattern2 = /Name:\s((?:(?!123)[^\n])+)/;

or

const pattern3 = /Name:\s([^;])+?)(?=;|123)/;

I successfully resolved my issue by adjusting the regular expression pattern to:

(Creator:)(([^;])+)(;|MIL)

This updated regex implies that the string must start with "Creator:", exclude any semicolons in between, and end with either a semicolon or 'MIL'.

Appreciate the help!
