Extract matching patterns from a string, string. Input vector. Either a character vector, or something coercible to one. pattern. Pattern to look for. The default interpretation is a regular expression, Solution: Use the Java Pattern and Matcher classes, supply a regular expression (regex) to the Pattern class, use the find method of the Matcher class to see if there is a match, then use the group method to extract the actual group of characters from the String that matches your regular expression. This is demonstrated in the following Java program:

Java: How to extract a group from a String that contains a regex pattern, Java pattern problem: In a Java program, you want to determine whether a String contains a regular expression (regex) pattern, and then you This article will provide a walkthrough of how to build a Windows Powershell script to extract data from a text file that matches a certain pattern and write it to another text file.
