Regex to match a string after colon ":"

Question

I need to identify a sub string from any string based on a regular expression.

For Example, take the following strings:

1. It sent a notice of delivery of goods: UserName1
2. Sent a notice of delivery of the goods: User is not found, UserName2
3. It sent a notice of receipt of the goods: UserName1
4. It sent a notice of receipt of the goods: User is not found, UserName2

I want to get the text after colon

1. UserName1
2. User is not found, UserName2
3. UserName1
4. User is not found, UserName2

Solution 1

You can use the regex like this:

":(.*)"

Then, you should use something like this one (on Java):

Matcher m = Pattern.compile(":(.*)").matcher(text);

if (m.find())
{
    System.out.println(m.group(1));
}

Solution 2

I think this is what you're looking for:

(?<=:).*

is there a way to do this so it excludes the colon? so for something:value, i would want it to return "value"

@Dan Hastings, did you try the code I've posted? It doesn't include a colon.

For me it returns the string with a colon at the start

@DanHastings But it can't. My example on Java works perfectly, so I can't tell you what you're doing wrong. You may ask a new question and provide the code that returns a string with a colon.
