Regex - Mass Search And Replace With Wildcards Or Reg Expression MyString.Length To Len(MyString)
Oct 14, 2010
I have a large ASP.NET project where I want to do a mass search and replace (about 3500 instances)
I want to change
If strErrorMessage.Length > 0
If strSomeString.Length > 0
If strWhatever.Length > 0
and any other similar call to the Length method from a string to the following
If Len(strErrorMessage) > 0
If Len(strSomeString) > 0
If Len(strWhatever) > 0
Anyway to reliably do this in one shot?
I can do a search and replace for something like If *.Length > 0 --> If Len(*) > 0
This just won't work though as it won't understand how to rearrange it properly. Currently have VS2010 and N++ at my disposal.

Using VB or C#, I am getting a string of variable length from the database. This information is sensitive information that only certain users will be able to see.I have two cases that will use the same logic (I think).scenario 1: replace all characters with xscenario 2: replace all characters with x except the last 4 characters (assume length > 4 - this check is being done).I thought that this would be easiest using Regex.Replace(input, pattern, replacestring). As opposed to a lot of string handling with substrings and forcing a length of 'x's.

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 am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.

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

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")

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.

determine the length of the value/string returned from a regular expression and convert it to a different string layout Alternate:replace the . with a / in the regular expression?replace a character with another character in a regular expression AND determine the length of that expression to replace it with a string output using that regular expression?IE if the regular expression returns 3.0.4.u1, i need this to read c3/0/4 up 1 instead.Below is the code I have so far (cut from the total program)
' original text
Dim myText As String = rawData
' capture the interface pattern (first # in string)
Dim interfaceUS As String = "s(d.d.d.ud)|(d.d.ud)"

somebody put a regex expression that will:find a chunk that starts with [% and ends with %] within that chunk replace all xml special characters with:& quot; & apos; & lt; & gt; & amp;leave everything between <%= %> or <%# %> as is except make sure that there is space after <%# or <%= and before %> for example <%=Integer.MaxValue%> should become <%= Integer.MaxValue %>
source:[% 'test' <mtd:ddl id="asdf" runat="server"/> & <%= Integer.MaxValue% > %]
result:'test' <mtd:ddl id="asdf" runat="server"/> & <%= Integer.MaxValue %>

I'm looking to do is scrub an html file for anything that resembles an IP address or any set of numbers for that matter. Normally what I would do is just using things like string.split to split out the html around areas that I want to search. What I am looking to do is be able to essentially search a large amount of characters for anything that matches this reg ex pattern.
Dim pattern As String = "^(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]):(d{1,4}|[0-5]dddd|[0-5]dddd|6[0-4]ddd|65[0-4]dd|655[0-2]d|6553[0-5])$"

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?

I am trying to replace text in my xsl file. I have to replace all the http and https. But I can leave any links that start with <a href>
Ie; http://www.google.com has to replaced. But < a href="google.com">google.com</a> has to remain as it is.
I am using regex to find all the http(s) and a hrefs in the text. I am struck here.
My code is,
Dim href As New Regex("(<a.*?>.*?</a>)", RegexOptions.IgnoreCase)
Dim hrefs As New Regex("http(s)?://([w+?.w+])+([a-zA-Z0-9~!@#$\%^&*()_-=+\/?.:;',]*)?", RegexOptions.IgnoreCase)
[Code].....
I am trying to use Regex.Replace to replace my https. But I am unable to write the evaluate function.
My regex.replace replaces all the values with a single value.

"^[_a-z0-9-]+(.[a-z0-9-]+)@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,4})$"
I noticed that in order for the e-mail address to validate, I need to put in at least 3 characters before the @ symbol. Is this a requirement? What if I just want to have an e-mail address with 1 or 2 characters before the @ symbol?

My coworker needs me to write him a regular expression for his vb.net app.I do not know vb and he does not know regex.The regex he needs is:/.*web id: ?(d+).*/iBasically he needs to search a string for something like "web id: 345" or "web id:2534" and retrieve the ID.He took what I gave him above and was able to put this together:
Dim strPattern As String = ".*web id: ?(d+).*"
Dim strReplacement$ = "$1"
GetWebId$ = Regex.Replace(LCase$(strNote$), strPattern$, strReplacement$)

I need to use RegEx.Replace to replace only certain named groups in my input string.
So I might have a pattern like:
"^(?<NoReplace>.+)(?<FirstPeriod>(d{2})|CM|RM|PM|CN|RN){1}(?<LastPeriod>(d{2})|CM|RM|PM|CN|RN){1}((#(?<NumberFormat>[#,.+-%0]+))*)$"
Tokens such as CM, RM are being replaced using Regex.Replace with a MatchEvaluator. However, this should only be replacing characters in the FirstPeriod and LastPeriod groups.
Example input:
"FIELDCNS 01CM"
Desired output:
[Code]....
Is this possible or am I best just pulling out the parts I want to replace and re-assembling afterwards?
