How we can manage regex in Java?
Yes, I did search regex topics, but I think it is strange in Java. What I would like to do is
My team <[email protected]>
with regex, I would like to get string between < > as [email protected]
Pattern p = Pattern.compile("(.+?)\\<.*?\\>?");
The above one didn't work.
Since it appears you're dealing with standard format email addresses (RFC 822) you might want to consider using the JavaMail API. It's designed to work with everything within the spec, whereas with regex you might miss some cases. The code for what you want is simple too:
String input = "My team <[email protected]>";
String email = new InternetAddress(input).getAddress();
Something like this, maybe?
final Pattern p = Pattern.compile("(.+?)<(.*?)>");
final Matcher matcher = p.matcher("Foo bar <[email protected]>");
if (matcher.matches()) {
System.out.println(matcher.group(2));
}
Edit: please also see @WhiteFang34's answer below which is a much better approach if you are dealing with email addresses.
find() can be used with "<(.*?)>", better for loop/multiple e-mails in text; final is also not needed (@Sae1962)Actually you need to call the find() method on a Matcher object in order to walk through your string. And as Petri Pellinen stated you should check for the right grouping.
Try the following code:
String str = "My team <[email protected]> My team <[email protected]> \n " +
"My team <xxx-yyyy@uucom> My team <[email protected]> " +
"My team <[email protected]> My team <[email protected]>";
Pattern p = Pattern.compile("\\<(.*?)\\>");
Matcher m = p.matcher(str);
while(m.find()){
System.out.println(m.group(1));
}
and check the groups fetched.
Results are:
[email protected]
[email protected]
xxx-yyyy@uucom
[email protected]
[email protected]
[email protected]
cheers!
