Looking for a Regular Expression that will extract all links out of Href=""
View 5 RepliesI would like to be able to extract a number from within a string formatted as follows:
"<[1085674730]> hello foo1, how are you doing?"
I'm a novice with regular expressions, I only want to be able to extract a number that is enclosed in the greater/less-than and bracket symbols, but I'm not sure how to go about it. I have to match numeric digits only, but I'm not sure what syntax is used for only searching within these symbols.

But that captures the symbols around the number as well as the number itself. I would like to only capture the number that is encased in the symbols and filter out the symbols themselves.

View 2 RepliesThis is a related to a previous question I have asked here, see the link below for a brief description as to why I am trying to do this.Regular expression from font to span (size and colour) and back (VB.NET).Basically I need a regex replace function (or if this can be done in pure VB then that's fine) to convert all ul tags in a string to textindent tags, with a different attribute value for the first textindent tag.For example:
<ul>
<li>This is some text</li>
<li>This is some more text</li>[code].....
Basically I want the first ul tag to have no indenting, but all nested ul tags to have an indent of 20.

View 3 RepliesI need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
