| A C# Web Spider written as a Web Service |
| C#Today |
| A Web Spider is a program that is used to navigate sites, follow links and collect various information. It is sometimes called a Web Robot. In this article. ST Tan & Aldy Karna discuss the subject, and show how a Web Spider can be written in C#. |

| Formatting with Regular Expressions |
| 4Guys from Rolla |
| If you're familiar with regular expressions, you know that they can be used for pattern matching and replacement in strings. Regular expressions true power lies in its ability to search for certain patterns and replace these patterns. For example, say that you have the contents of an HTML page in a string, and you want to find any occurrence of a particular word and highlight it in the user's browser. This can be done, rather simply, with regular expressions. |

| Masked Edit Control written in C# that uses Regular Expressions |
| C# Help |
| We programmed a masked textbox control with C# that will convert the mask into a regular
expression for each character in the field. It is designed to accept a user defined mask
or a regular expression that defines each character in the field. If you pass it the mask
as a string using the characters listed below, it will build the regular expression for you.
It then loads the regular expression into an array which is used to validate and control the
behavior of the field. There is an error provider message and a tooltip associated with the
control. |

| The best regular expression on the Internet |
| STANDARDIO.ORG |
| Recently I decided I wanted to build an Internet spider. There was no client paying for it, no boss asking for it. It’s just something I’ve always wanted to do. Thanks to the .NET Framework objects System.Net.HttpWebRequest and System.Net.HttpWebResponse, this is relatively easy. The hardest part I ran into while writing the code was scanning for HREF’s on a page. I thought this might be the easiest part when I started, but in terms of lines of code per hour, this was by far the most difficult portion of my spider. In this scenario a regular expression is needed to scan the HTML the spider has downloaded for more HREF’s so it can continue crawling the web. |

| Using Regular Expressions |
| 4Guys from Rolla |
| Regular expressions are a neat and efficient way to perform extremely powerful string pattern matching and replacing. For example, imagine that you had an HTML document and you wanted to pick through it to retrieve all the text between any bold tags (between <b> and </b>). Although this can be done with String class methods such as IndexOf and Substring, it would involve an unnecessarily complex loop with some ugly code. Instead, a relatively simple regular expression could be used.

| Working with Web Data in C# (Screen Scraping) |
| C#Today |
| Think of the World Wide Web as a giant database management system in which the web sites are the databases and the web pages are the database tables. Now think about how useful it would be to gather data from those tables in a form that could be processed, queried, and combined with other, otherwise unrelated, data in new combinationsusing C# and the .NET framework. In this article, Tony Loton looks at how to: drive HTTP GET and POST requests to web sites using the WebRequest and Stream classes, capture the responses via the WebResponse class, and pick out specific nuggets of information from a web page using regular expressions and the Regex class. The end result is a small but useful engine and a demonstration application, that goes a long way towards allowing data to be selected from web pages as though selecting from relational database tables, using SQL syntax. |
