Regex - .net Regular Expression To Match Two Words Separated By Comma Not Working?

Mar 4, 2010

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 & "#"
Next

VS 2010 RegEx - Split On Comma Character, Excluding Those In Quotationmarks?

Aug 9, 2011

Given an input string like the following:I, Need, Some, Coffee, Before, I, "Fall, Asleep" I need to split this into parts like so:

I
Need
Some

[code]...

Splitting on the comma character alone is easy enough, but how can I handle the quotationmarks? Regular expressions is not on my strong side, and I have been googling for quite a bit without any good results.

Get A Regular Expression That Can Validate That A String Is An Alphanumeric Comma Delimited String?

Jun 23, 2011

I need a regular expression that can validate that a string is an alphanumeric comma delimited string.

Examples:

123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid

This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$

Comma Delimited Line Split?

Jan 9, 2011

I have spent a long time debugging an application that occasionally goes awry, it ends up that the problem is that the comma delimited text files that I am looping through occasionally inserts a comma within one of the fields.

At any rate, I was loading the text file into Excel to try and spot the error which was of no help, somehow Excel parsed out the field correctly and didn't use that extra comma as a delimiter. Is there any way I can get my application to do the same?

And example field value is: "7-8-ALL (1,2&3)", but of course my split code turns this into two separate array values.

.NET Regular Expression To Split Multiple Words Or Phrases?

Mar 19, 2010

I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring?

Private m_Reg As Regex
m_Reg = New Regex("([^""^s]+)s*|""([^""]+)""s*")

VS 2010 Proper Regular Expression (Regex) Pattern?

Apr 24, 2012

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.
