My coworker needs me to write him a regular expression for his vb.net app.I do not know vb and he does not know regex.The regex he needs is:/.*web id: ?(d+).*/iBasically he needs to search a string for something like "web id: 345" or "web id:2534" and retrieve the ID.He took what I gave him above and was able to put this together:
Dim strPattern As String = ".*web id: ?(d+).*"
Dim strReplacement$ = "$1"
GetWebId$ = Regex.Replace(LCase$(strNote$), strPattern$, strReplacement$)

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.

I'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];
}

I'm sure it can be done easily with a regular expression, but I just can't get the hang of it.
I need a regular expression that requires at least ONE digits and SIX maximum. I've worked out this, but neither of them seems to work. ^[0-9][0-9]?[0-9]?[0-9]?[0-9]?[0-9]?$ ^[0-999999]$
View 4 RepliesIt 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.

View 5 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.
I have written code to pull some data into a data table and do some data re-formatting. I need some help splitting some text into appropriate columns.
CASE 1
I have data formated like this that I need to split into 2 columns.

column is the first 11 characters That is easy.column 2 should contain all the text after the first 11 characters up to but not including the first number.The last column is all the text after column 2
I know it may be quite easily for you. i have a text which contains 40 lines, I want to remove lines which starts with a constant text. check below data.
When I used (?mn)[+CMGL:].*($) it removes the whole text , when I use (?mn)[+CMGL:].*(
) , it only leaves the first line.

I 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 & "#"
