Asp.net - .Net Regex Match Grouping And Repetition Question?
May 27, 2009
I have the following VB.Net 2.0 in an ASP.Net app:
output = Regex.Replace(output, "<p>(?:(?:<!--.*?-->)|&(?:nbsp|#0*160|x0*A0);|<brs*/?>|[su00A0]+)*</p>", String.Empty, RegexOptions.Compiled Or RegexOptions.CultureInvariant Or RegexOptions.IgnoreCase Or RegexOptions.Singleline)
Am trying to match characters or combination of the characters i specify in any order they appears
vb Regex.IsMatch(teststring "[nuls]")
what i want matched is either any single character, or combination of any of them in any oder. this means that it should not match any character not specified in the pattern.
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'm creating a program in VB.NET to output multiple images. Some images will have the same file name. If there is multiple files with the same name I want to add "_1_" to the end of the file name. If the "_1_" file already exists I want to increment the 1 to be "_2_". If this file already exists I want to continue incrementing the number ultil it doesn't exist. So for example "filename", filename_1_", "filename_2_", etc. Here is the code that I have tried
The quick brown fox jumps over the lazy dog" is an English-language pangram, alphabet! that is, a phrase that contains all of the letters of the alphabet. It has been used to test typewriters alphabet. and computer keyboards, and in other applications involving all of the letters in the English alphabet.I need to get the "alphabet." word in regex. In the above text there are 3 instances. It should not include "alphabet!". I just tried regex with
MatchCollection match = Regex.Matches(entireText, "alphabet.");
but this returns 4 instances including "alphabet!". How to omit this and get only "alphabet."
I would like you to help me out with the strings, which I find it difficulty to get from the html class. The first string I uses as pattern1 string, which it connected to the server to get the showtitle string from the html class, it is working fine. I couldn't be able to get the string on the second paragraph from the html class with pattern2 string, as the text goes on the blank. I need to get the string from the html class. The third pattern string, I am trying to get the string at the end of the html class so I got the blank text.
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, $m);
I'm having a problem trying to match a certain input.The rules of the input is the following: Whole numbers are entered into a text box and they must be separated by a space. There can be anywhere from 1 to infinite numbers. The last character entered must be a digit (no trailing space). Every space delimite must be only 1 space. I'd prefer to handle this all in regex.
My regex: (?=\d$)^(\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.
1 <span class='Txt9Gray'>Decisions ( </span> I'm trying to grab the '1' from this string. Before the '1' is another span, but I can't use that as a marker because it can change from page to page. Is there any regex expression that can simply grab the '1'.
The word 'Decisions' will always exist. That's my main way to find this line. Here's what I have been trying to no avail:
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)*") If MatchObj.Success Then
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) ).
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)
Well my question is simple, I want to match a string with following attributesNo white spaceMust start with a letterMust not contain any other special characters other than nderscore

I have to match string like "DAY1","DAY2","DAY3"....."DAY31" with regex in vb.net. I tried something like this - ^?DAY(0[1-9]|[12][0-9]|3[01])$ but it did not work.
The pattern should have succesfull match if the source string is either DAY1 or DAY2 or DAY3 to DAY31 like so.
