I am trying to validate via RegEx as follows.If Regex.IsMatch(Output, "" & "Serial)" & "") Then'do something
end if but i get this Argument exception

parsing "Serial)" - Too many )'s. I do understand the error, but how should i modify the RegEx expression?

UPDATE. The word "Serial)" is generated dynamically. That means at least for me i could get another exception for another character too.

Concatenating A Variable With A Regex Group Match In Regex.replace?

Apr 5, 2012

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?

.net - Replace In Regex Match?

Mar 26, 2012

I'm using the following VB.net Code to find phone numbers in HTML and make them "clickable":

Regex.Replace(pDisp.Document.Body.innerHTML, "([0-9+ ]{3,6}[s]{1,1}[0123456789 -/]{4,15})", "<a href=http://DIAL/$1>$1</a>")

There appears an issue if the numbers contain white spaces, for example:

089 12233 455

This will be replaced with:

<a href=http://DIAL/089 12233 455>089 12233 455</a>

Is there a way to get

<a href=http://DIAL/08912233455>089 12233 455</a>

instead?

Convert This PHP RegEx Match Pattern To .Net?

Feb 8, 2012

This is a pretty complex regular expression that returns an array of key/value pairs from a proprietary string of data. Here is sample of the data, in case the express can not be used in .Net and another method needs to be used.

0,"101"1,"12345"11,"ABC Company"12,"John Doe"13,"123 Main St"14,""15,"Malvern"16,"PA"17,"19355"19,"UPS"21,"10"22,"GND"23,""24,"082310"25,""26,"0.00"29,"1Z1235550300000645"30," PA 193 9-05"34,"6.55"37,"6.55"38,"8.05"65,"1Z1235550300000645"77,"10"96,""97,""98

If you look closely you see its key,"value",key,"value" The only guarantee on formatting is that each key value pair is separated by a comma, and each value will always be encased in double quotes. The main problem (the reason you cant explode it) is the poor choice of the previous coder to separate keys and values with the same character as the entries. Anyways, out of my hands. Here is a working PHP example.

function parseResponse($response) {
// split response into $key, $value pieces
preg_match_all("/(.*?),"(.*?)"/", $response, $m);

Regex LookAround : Match A Certain Input?

Sep 15, 2010

I'm having a problem trying to match a certain input.The rules of the input is the following: Whole numbers are entered into a text box and they must be separated by a space. There can be anywhere from 1 to infinite numbers. The last character entered must be a digit (no trailing space). Every space delimite must be only 1 space. I'd prefer to handle this all in regex.

My regex:
(?=\d$)^(\d+[\x20]?)+$
([\x20] is a space character)

It doesn't like the lookahead before the carot nor does it like a lookbehind after the $. If I leave the lookahead out, ^(\d+[\x20]?)+$ will match as needed for everything except to ensure the last character entered is a digit.

REGEX Match With Math And Replace

Jun 3, 2011

I'm wanting to search a RTB for all X coordinate values and convert them to SI mm units.

I have two issues: 1. My code is stopping after the first instance of match.success, I'm guessing i'm using nextmatch incorrectly? I have also tried matchcollections with no success.

2. I fear once we get it progressing to the next X value, any multiple X values with the same dimension will be replaced with my replace command, causing the new value to be converted again.

Dim MatchObj As Match = Regex.Match(RichTextBox1.Text, "[Xx](?<X>(d*.{1,1}d{1,4}))(s)*")

C# - Using Regex To Match Any Character Until A Substring Is Reached?

Jul 18, 2011

I'd like to be able to match a specific sequence of characters, starting with a particular substring and ending with a particular substring. My positive lookahead regex works if there is only one instance to match on a line, but not if there should be multiple matches on a line. I understand this is because (.+) captures up everything until the last positive lookahead expression is found. It'd be nice if it would capture everything until the first expression is found.

Here is my regex attempt:

@@FOO[(.*)(?=~~)~~(.*)(?=]@@)]@@

Sample input:

@@FOO[abc~~hi]@@ @@FOO[def~~hey]@@

Desired output: 2 matches, with 2 matching groups each (abc, hi) and (def, hey).

Actual output: 1 match with 2 groups (abc~~hi]@@ @@FOO[def, hey)

Is there a way to get the desired output?
