获取字符串的特定子字符串

Question

I was wondering if anyone could help. I have one big string which would be similar to below:

Name="firstName" Description="this is a test description" date="01/01/2016".  

What I want to do in java is to simply abstract a small part of this string, namely the bit after description which is in quotes which would ideally give me "this is a test description". Would anyone be able to guide me on how to achieve this?

Thanks.

Answer 1

You can use the following regex: .*Description=\\"([\\\\w ]+)\\".*" . The string you want is capture group 1. For example:

    Pattern pattern = Pattern.compile(".*Description=\"([\\w ]+)\".*");
    Matcher matcher = pattern.matcher(input);
    System.out.println(matcher.group(1));

Answer 2

If the string is exactly as you have there?

Let's say the string looks like this, you could use split.

 String description = str.split("\"")[3];

This will give you exactly the part between the Description quotation marks, with just a split. You can run it here with a small example

As a small note: this assumes there are no " inside the actual content parts. (In firstname, I'm assuming this is a safe guess, but I'm not sure if the same can be said for the description part)
