The most important part of the solution involves using the Pattern. As the name implies, this tells the Pattern class to look across multiple lines when parsing the String.

Another important part of the solution is to use a while loop with the find method to make sure you find all occurrences of your regex pattern in the input String. If you only use an if statement with the find method, you will only get the first match. By Alvin Alexander.

Copyright by Refsnes Data. All Rights Reserved. Powered by W3.Problem: In a Java program, you want a way to extract a simple HTML tag from a Stringand you don't want to use a more complicated approach. Solution: Use the Java Pattern and Matcher classes, and supply a regular expression regex to the Pattern class that defines the tag you want to extract.

Then use the find method of the Matcher class to see if there is a match, and if so, use the group method to extract the actual group of characters from the String that matches your regular expression.

In the following source code I demonstrate how to extract the contents from a code tag from a longer HTML string:. By using a group to extract the contents between the HTML opening and closing code tags, the output from this program is:. I then access this group using this line of code:.

In a more robust example, where you want to find and extract the contents of every code tag, your code would look more like this, using a while loop with the find method:. This code repeatedly calls the find method and prints the contents of the matching group until find doesn't locate any more matching patterns in the given String. In summary, if you wanted to see a simple way to extract an HTML regular expression pattern from a String in Java, I hope this is helpful.
