Say I have this list (with unknown delimiters):
ABC-12345, DEF-34567; WER-12312
ERT-23423
I know the regex to mach what I need is: [A-ZÆØÅ]{3}-d{5}. But how do I use the Group or Capture of the .net Match class?
This is my first attempt:
Public Function ParseSites(ByVal txt As String) As List(Of String)
Const SiteIdRegEx = "([A-ZÆØÅ]{3}-d{5})"
Dim list As New List(Of String)

I'm trying to find a way where i can make it loop through the results of my capture group regex query.
For instance if i have this:
VB.NET
Dim matches = Regex.Matches("<h1><span>test</span></h1>", "(?<=<h1>(<span>)?)(?<data>.+)(?=(</span>)?</h1>)")For Each item In matches.OfType(Of Match)()Console.WriteLine(item.Value)Next
And i'm trying to get the contents of <data>, how do i do it without it printing out the junk before it and after it?
quantifier isn't working, its supposed to make the <span> tag optional in the query, but it isn't.
I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?
(<td [^>]+>
ss|[^, ]<a href=""http://www.test.com/member.php?action=profile[^>]+>(<span [^>]+><strong>|<span [^>]+>|))[^<]+(<span [^>]+>|</strong></span></a>|</a>|</span></a>)
How do i turn that into a capture group so it only gets the text that is bold and removes the rest?Also how do i loop through all the result from that captured group text?
I was able to extract href value of anchors in an html string. Now, what I want to achieve is extract the href value and replace this value with a new GUID. I need to return both the replaced html string and list of extracted href value and it's corresponding GUID.
My existing code is like:
Dim sPattern As String = "<a[^>]*hrefs*=s*((""(?<URL>[^""]*)"")|('(?<URL>[^']*)')|(?<URL>[^s]* ))"

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)

I have the following text that I am trying to parse:
"user1@emailaddy1.com" <user1@emailaddy1.com>, "Jane Doe" <jane.doe@ addyB.org>,
"joe@company.net" <joe@company.net>
I am using the following code to try and split up the string:
Dim groups As GroupCollection
Dim matches As MatchCollection
Dim regexp1 As New Regex("""(.*)"" <(.*)>")
matches = regexp1 .Matches(toNode.InnerText)
For Each match As Match In matches
groups = match.Groups
message.CompanyName = groups(1).Value
message.CompanyEmail = groups(2).Value
Next
But this regular expression is greedy and is grabbing the entire string up to the last quote after "joe@company.net". I'm having a hard time putting together an expression that will group this string into the two groups I'm looking for: Name (in the quotes) and E-Mail (in the angle brackets).
the regex:
# Region
<tr>
s*<tds+class="grey11">Region:</td>s*
<tds+class="b11s+b">(?<Region>.+?(?=</td>))</td>
s*

I've been working straight since yesterday trying to get this to work. I'm a noob to RegEx and I've tested out about 5 different RegEx "builders" but each of them require you to navigate through the options to build the Regex...each of them has failed when I try to use them.Is there an application out there free/paid where you select the line you want to grab and the RegEx is auto generated from that highlight rather than having to try to build the line of code?

View 1 RepliesSo I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

I want to divide the content in my application to groups each group has its own rectangle border with the group name located at the top border, i've seen it before and i'm not sure what is the correct name of this control, anyone knows what I'm talking about ? EDIT: Ok, I found the Groupbox Control but how do i use it? should i just drag other controls inside it or i should add controls directly into it?

When I first saw Silverlight, I thought that there was a How Do I: video that demonstrated how to capture the PC screen and save it in a WMV file. Since I can't find anything like that I'm wondering if I was dreaming or it has been removed from the Net. My goal is to create a video capture Class that I can use to demonstrate my program and add the feature in my program so the user can record any issues they are having with my program and send it to me. This way I can see what issues they are having with my program.
View 2 RepliesI want to allow my user to add urls to a database, much as a user might add file names. I have a form with a label, a textbox, and a browse button. I would like the browse button to load the user's default browser and then have the final url appear in the textbox when the browser closes. I have not been able to do that, but I have come close. I have not found a way to capture the url from an arbitray browser, so I instead load ie.exe and then capture the url with an OnQuit handler. That works (even verified by the debugger) but I am unable to get the url to appear in the textbox without actually clicking in the textbox once ie closes. I would like a suggestion as to how to avoid making my user click in the textbox and, if possible, to load the user's default browser and still capture the url. Here is my code for the Browse button (IE is defined at the class level as Dim WithEvents IE As SHDocVw.InternetExplorer):
theURL = ""
IE = New SHDocVw.InternetExplorer
AddHandler IE.OnQuit, AddressOf HandleIEQuit
