Regex - .net Regular Expression To Match Two Words Separated By Comma Not Working?
Mar 4, 2010I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)", RegexOptions.Singleline)
output = re.Replace(userName, "$2 $1")
So why doesn't the following code store "#Test##Person#" in output variable.
Dim output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)")
For Each Match As Match In re.Matches(userName)
output &= "#" & Match.ToString & "#"

View 4 RepliesC# - Using Regex To Match Any Character Until A Substring Is Reached?
Jul 18, 2011I'd like to be able to match a specific sequence of characters, starting with a particular substring and ending with a particular substring. My positive lookahead regex works if there is only one instance to match on a line, but not if there should be multiple matches on a line. I understand this is because (.+) captures up everything until the last positive lookahead expression is found. It'd be nice if it would capture everything until the first expression is found.
Here is my regex attempt:
@@FOO[(.*)(?=~~)~~(.*)(?=]@@)]@@
Sample input:
@@FOO[abc~~hi]@@ @@FOO[def~~hey]@@
Desired output: 2 matches, with 2 matching groups each (abc, hi) and (def, hey).
Actual output: 1 match with 2 groups (abc~~hi]@@ @@FOO[def, hey)
Is there a way to get the desired output?

.net - Extract A Particular Value From An INI File Using A Regular Expression?
Dec 22, 2009I 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.

Use The Regular Expression To Extract The Username And Password?
Jan 4, 2010I've got a question about Regular Expression in Visual Basic. I normally program in PHP and I can do the following in PHP, is this also possible in VB? Text to match:
user-123456:3a9va6
user-748538:870fas
user-384593:fs8s9s
user-575432:0das0d
Then I can use the following Regular Expression to extract the username and password:
(user-[0-9]{6}).*([a-z0-9]{6})
If I use it with the following php code, it generates a 2-dimensional array with every user and it's password in the $matches array:
PHP
preg_match_all("/(user-[0-9]{6}).*([a-z0-9]{6})/siU", $input, $matches, PREG_SET_ORDER)
Then I'm able to loop through all user and their username:
PHP
foreach($matches as $match)
{
echo $match[0].":".$match[1];
}

View 4 RepliesVS 2010 Proper Regular Expression (Regex) Pattern?
Apr 24, 2012It seems up until now I've never used Regex, nor even heard of it. But once I did I realized how extremely useful this is. Having said, it's been 2 days since I've began looking into constructing my own patterns. My most recent being for decimals. Is the pattern I provided below "proper"? and are there also any improvements I could be making for a more efficient patter, which would minimize any possibility of a loophole? [code] So for my use, this is doing what it's supposed to being doing under every test I can through at it. But do mind the 0. and .0, I have a function to normalize these as they are proper, I just pad the left and right accordingly. I found most regex questions asked here..and yes I am doing this in vb.net so it fits. If not, then feel free to move this post somewhere else better suited for the topic of discussion.
