Parsing Out The Contents Within Brackets Using Regex?
Dec 20, 2011
I'm sure this is simple and I'll probably be embarrassed to have this question in my profile but I can't seem to get this Regex correct.
I'm tring to extract just the digits from the last group of the following string:
Properties[1].Securitymeasures[14].AdditionalSecurityType
so I want to have a regex that will return 14
The Regex I have come up with is:
[(d)+]
However - the match is returning "[14]" - including the brackets and I do not understand why. I have surrounded the d with parenthesis which should mean that this is the data I want to capture.

I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))

I am trying to build an application which does the following :
1) write some text in a richtextbox
2) when user clicks a button, the app will replace the text with another text in {} braces.
what I want is that the next time, the regex searches for any text it should exclude those which are present in {}. for eg : my world is good world and a happy world and will be a better world for everyone. first pass - change word "world"

Just have a list of words, such as:
gram (g)
kilogram (kg)
pound (lb)
just wondering how I would get the words within the brackets for example get the "g" in "gram (g)" and dim it as a new string. Possibly using regex?

I have some existing code that looks something like this:
[tag:cb cbid="12345" cbwidth="200" cbclassname="calloutbox" cbposition="left"] Lorem ipsum dolor sit amet, consectetur adipiscing elit.
[tag:cb cbid="123" cbwidth="200" cbclass="calloutbox2" cbposition="left"] Suspendisse eleifend enim a magna pretium porttitor.
I need to write a VB .Net global function that will match these [tag:cb] and take the optional parameters and rewrite the string with Html tags.
<div id="12345" width="200" class="calloutbox" position="left">content (based on id)</div>

I'm parsing fixed length file with .NET 3.5 and Regex. This file is from bank. In customer name sometimes there is one characters from this set &,(),[],',"". These are characters, so far I've encountered. There can be anything else. Because of this my regex is failing. My regex is [A-Za-z0-9s-.,'""""(){}[]]{35}. Is there any wild card I can use for special chars rather than specifying individually. I also tried . but didn't work.

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.

<dd itemprop="softwareVersion">1.8.1.0</dd>
1.8.1.0 is not the same all the time, It changes and it could be 2.01.01 , 3.2 , 5 , 1.21 etc
Is there anyone who can make a regex for it ?

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

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?

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?

What is the difference in usage of brackets around namespace? such as:
[Assembly].Load("assemblyname")
Assembly.Load("assemblyname")
What makes the brackets special?
I know the usage of the brackets in variable declaration... meaning allow usage of reserve keyword.

Public Class Form1
Private Sub Button18_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button18.Click
Dim i As Integer = 0
Dim j As Integer = 0
Dim x As Integer = TextBox1.Text.IndexOf("sin", i)
