In this part of my Java Video Tutorial, I cover Java Regular Expressions. You use regular expressions when you want to search for data. You then use codes to define what that data looks like.
So, if you are looking for a 5 digit number, you could type \\d{5} and Java does the rest!
The code that follows the video will help you see how easy regular expressions are.
In this part of the JavaScript Video tutorial I will introduce Regular Expressions. A large number of people have trouble with Regular Expressions. I think it is because the name is so confusing? They aren’t!
A Regular Expression is a series of codes used to describe a series of characters in a string.
They are used to search for a specific string of characters in another string.
In todays Programming tutorial I show you how to grab information from a website using Regular Expressions in PHP. The information was particularly hard to get for the following reasons:
I did it though using Regular Expressions and I’ll show you how.
In this video tutorial I show you how to do many things with MySQL. I cover the following MySQL Statements in depth:
Here I show you how to use many string manipulation methods in PHP. Also, I finish showing you how to use regular expressions.
You should watch the previous 2 PHP Regular Expressions video tutorials before you continue on to this one. They are avaialable here PHP Regular Expressions & PHP Regular Expressions Pt 2
I specifically cover the following PHP Methods in this tutorial:
In this video I’ll continue to show you how to retrieve specific information using Regular Expressions and PHP. I’ll specifically cover how to find:
In this video, I provide a bunch of examples on how to use Regular Expressions in Python. I show you how to search for numerous different types of data and output and manipulate that data.
I’ve provided all of the code after the video and if you have any questions, leave them in the comment section below.
In the next article, I’ll show you how to grab information from any web page and do what ever you want with that information.

Today I’m going to continue teaching you everything about Javascript. If you haven’t read my other Javascript tutorials they are available here:
You must read these tutorials before you have any hope of understanding the code that is coming. Like in the last tutorial I will teach you Javascript by walking you through a working script. As the title says above, this tutorial will focus on Regular Expressions, Form Validation and Event Handlers.
