Need help with regular expression

I need help design a reg exp.
I am parsing an html file to get the input values, here is one example

<input VALUE="Staff Writer" size=60 type="text" name="author">

Can I grab the value "Staff Writer" if name = "author"? is it possible using
regexp?

Thanks

The following sites provide a wealth of information on regular expressions.

A tutorial & reference on using regular expressions:
http://www.regular-expressions.info/

The MSDN's documentation on regular expressions:
http://msdn.microsoft.com/library/de...geElements.asp

Instead of writing your own parser or using RegEx, have you considered using
a SgmlReader (HTML reader)?

Hope this helps

Thanks for the links. Now I can get most of the information except for one
thing. There is a <textarea> tag anding with </textarea> and I am trying to
capture the text between these two tags and I am not getting it. Could it be
becuase of new line characters?
Here is my regex string
textarea.*name= ""text"" cols=60>(?:""(? <1>[^""]*)""|(?<1>\S+)) .*<textarea>

Thanks

I must create a routine that finds tokens in small, arbitrary VB code snippets. For example, it might have to find all occurrences of {Formula} I was thinking that using regular expressions might be a neat way to solve this, but I am new to them. Can anyone give me a hint here? The catch is, it must only find tokens that are not quoted and not commented; examples follow

Usually when you make regular expression to extract text you are starting from simple expression. When you got to know target text, you are extending your expression. Subsequently very hard to ready long set of special symbols and impossible to improve such expression. We have to create ’smart’ regular expression. Instead of write one line expression we prepare multi line text from which we shall generate our long expression. Here is a simple...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
