I have this

How do I use a regex inside this string?
Using VB.NET, Is there a way to do this RegEx call in 1 step... instead of 2-3? I'm trying to find the word "bingo", or whatever is between the START and END words, but then also inside the inner FISH and CAKES words. My final results should be just "bingo".
Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"

I want to get a string between 2 strings using Regex.The the string I have is "<b>hello</b>", now I want to get the string between <b> and </b>. I guess its something like Regex(String, "<b>(.+)</b>" but I'm not sure how to do it. I know there is this function called GetBetween but I guess this is a better way.
View 9 RepliesI'm trying to figure out how to use regex to grab the information between the double quotation marks, it will always be in this format:
Client: ("COMMAND", "DATA(if it exists)", "ARG1(if it exists)", "ARG2(if it exists)", "ARG3(if it exists)")
It will ALWAYS have the "COMMAND" string there no matter what, and when the "DATA" string

I am trying to perform calculations on Regex substrings. I would like to do something like (see $2)
lblResult.Text = reg_exp.Replace(txtInput.Text, "$1" & "$2" * 0.039 & "$3" & "$4" & "$5")
I can only do this like:
For Each RxMatch In reg_exp.Matches(Me.txtInput.Text)
Me.lblResult.Text = Me.lblResult.Text & _
RxMatch.Groups.Item(1).ToString & _
Math.Round(CDbl(RxMatch.Groups.Item(2).ToString) * 0.03937, 4) & _

To search a pattern containing parenthesis, they must be escaped using backslashes. So to search for (Streetname) you must use (Streetname). If you don't use , whatever is between () will be retained and available for reference through the variables $1, $2 etc... Exemple, in the sentence "It's worth noting that (StreetName) can be anything...(Post), (TreeStump)", $1=StreetName, $2=Post, $3=TreeStump

Just have a list of words, such as:
gram (g)

I have buttons generated through code (dynamically). I have to associate an event (the same) to them. I use AddHandler button.click, AddressOf mysub.The issue is that mysub gets a string (mysub(string)), but AddressOf doesn't accept a parameter inside the routine. How can I do this? Using also an alternative to AddressOf.

This is the String:
Quote:
<a title="I Need this String" href="/page/view_7894135/I_Need_This_String.html" class="tinylink">I Need this String</a>
This was my RegEx but it doesent work. I tried everything:

the string ordering does not matter Z, X, or c can be any order in the string but the regex must fail if all three are not present. I can easily do Three different regex but was wonder can this be done with one expression?

I'm trying to find a pattern in a string, I guess is very easy but I'm terrible in regular expressions. I have a big text and I need to find all the next type of pattern:
{a|b|c}
That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using vb.net 2005.
how can I get the protocol and the domain form a string?

I am trying to gather all numbers in this string which is the name of an image file. The name of the string is ABC09072009XYZ777000111.jpg. When I use
Dim rx as new Regex("d")
Console.Writeline(rx.match(input))
It only returns the first set of numbers before the xyz. I need them all.
I have a string (bufferedstring) which contains:
blah blah blah Version V3.5/7(030114) blah blah blah blah
I'd like to parse out the Version V3.5/7(030114) part using a Regex or Substring, but not sure how. The surrounding text could be dynamic in length and the 6 numbers between the parenthesis could be a different length as well (maybe 4).
how would I get just that string out?
I have a long string of HTML code that contains several quotes around objects in the string. I have a Regex.Replace() function to change the "img src" tag, due to the way its stored in a database.
Here is my string: <p><strong><u><font color="#cc0099">RICH TEXT BOLD UNDERLINE. PICTURE TO APPEAR BELOW</font></u></strong></p><p><strong><u><font color="#cc0099"/></u></strong></p><p><img src="/inlineimages/WorkOrder/6/1245981403232.jpg"/> </p><p /><p>W00T!</p>
[Code].....
Notice how the "<font color=" has single quotes around its value, and "<img src=" has single quotes, with a double quote jammed in between?
Also, is there an automated way to go from my initial string, to the "Dim input As String" I created? I had to manually type that out, editing the quotes just to try and make it work.
I have a string like
FVAL(XXX)="TRUE" AND FVAL(TT)="FALSE"
I want to replace all "TRUE" and "FALSE" by TRUE AND FALSE.
Now the resultant string should be
FVAL(XXX)=TRUE AND FVAL(TT)=FALSE
Will the code shown below be upto the mark for this.
Regex.Replace("FVAL(XXX)=""TRUE"" AND FVAL(TT)=""FALSE""", "[""]TRUE[""]", "TRUE", RegexOptions.IgnoreCase)
I have a simple string : s:10:"char1";s:2:"13";i:1;a:8:, i'd like to match that 13 from inside " ", in PHP i would do something like :
/s:dd?:"char1";s:dd?:"(.*?)";i:dd?;a:dd?:/i but i'm not good in vb's match methods,so please give me full example how i can match what i need ( it is possible to be multiple matches (2) ).
