View 6 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.
I was wondering why some of the implementations were not working. In fact, the only one that did work was the one described by Matthew Flaschen. 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.
I'm trying to use regular expressions to take this number and only filter out any dashes, and just see a number:1-742-852-5412..I've tried ^d{7,}$, however, it doesn't recognize the numbers becuase it's including the dashes. how put together a regular expressions this disgregards the dashes?

I have just coded the below regular expression. I have a mini rich text editor on a web page (very similar to the one I am using to post this question) and I want to make use of a double asterisk to indicate which words/phrases should be wrapped in a strong tag. The aim is to allow the user to add pre-defined HTML elements without actually having to submit HTML.

Maybe I am over-optimising this, but I want to know if this can be made more efficient?
It is a little like a search and replace, I want to replace any string that contains any substring in parentheses with the same string but the words in parentheses colored RED: Eg
Take this text in TextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
and convert to this text in RichTextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
I had a regular expression which parses out value.

I want to extract a URL value from an INI File as such:
[DEFAULT]
BASEURL=http://www.stackoverflow.com/
[InternetShortcut]
URL=http://www.stackoverflow.com/
So I can get the URL value as the only Match from the Regular expression - but I don't understand enough about them (yet) to do this. I have seen RegEx examples that will parse any INI file and get the Name, Value Pairs I just want to get the URL value only from a file no matter what else it contains. My aim is to have something like this:
Dim _pattern As New Text.RegularExpressions.Regex("RegEx")
Dim _url As String = _pattern.Match(iniContentString).Value
It seems simple but I cannot seem to create a specific case RegEx where I want everything from "URL=" to the vbCrLf at the End to be my "Match". I have refered to Regular-Expressions.info which has been a help before but still cannot get this simple example to work.
have a regular expression in .NET, which will allow only 24 hr time format in the textbox.

I am trying to validate a csv file of domain names (eg. @google.com, @xyz.co.uk, @xyz.edu etc.) I am using the following Regular Expression:
Regex(@"@(?:[a-zA-Z0-9-]+.)+[a-zA-Z]{2,4}$", RegexOptions.Compiled);
Is there scope for improvement on the above?
Regex(@"@(?:[a-zA-Z0-9-]+.)+[a-zA-Z]{2,4}$", RegexOptions.Compiled);
Using the above, I want to pass only values like @gmail.com, @xyz.edu, @co.uk etc...
But I find that the values like abc@gmail.com (valid email ids) also pass through.
