Regex - Regular Expression That Requires At Least ONE Digits And SIX Maximum
Jan 21, 2011
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]$

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$, strReplacement$)
[code].....

I'm trying to find the right RegEx to capture some (potentially) repeating data. I don't know how many times it will repeat. If I give an exanple of the data and what I want to capture can anyone point me in the right direction? It's the .Net regex engine (Visual Basic)

Excel returns a reference of the form
=Sheet1!R14C1R22C71junk
("junk" won't normally be there, but I want to be sure that there's no extraneous text.)I would like to 'split' this into a VB array, where
a(0)="Sheet1"
a(1)="14"
a(2)="1"
[code]....
I'm sure it can be done easily with a regular expression, but I just can't get the hang of it.

It 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.

This 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 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.
+CMGL: 0,1,,159

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 & "#"

I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

Im wanting to use a textbox for the entry of Decimal figures (currency). Is there any way I can have it so if a user does not put a decimal figure (ie 15 instead of 15.00) it will put it on.
I tried a masked textbox, but that means i have to set the maximum number of digits before the decimal too which is no good.

I have the following regular expression for validating a file name:

I can get it to work in VB.NET but not C#. I can't figure out why it works in one but not the other.

As far as I can tell the patterns are identical in both languages with escaping. When I run the VB code I get a match. When I run the C# code I get nothing.

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.
[code...]
Maybe I am over-optimising this, but I want to know if this can be made more efficient?

and convert to this text in RichTextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
