.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?
Oct 8, 2011In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

View 9 RepliesRegex.Replace With A String Of HTML
Jun 25, 2009I 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.
Regex - Replace Space In A String At Random Position In .net?
Mar 1, 2012I want to select a random space in a string and replace it with a word (%word%) but there is a problem. The position cannot be fixed as i want it to be inserted at a random break. Few things which iam considering :
1)break the string at a space and merge it with the word
2) find a random space and replace it with the word. I like this point and so far all i have is break the selectedtext into string array and then iterate over each line. But i don't know how to find a random string position? Any short and sweet code please?

Regex Replace All Characters In Variable Length String?
Oct 6, 2010Using 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.
View 2 Replies.net - Replace Content In A String Based On Regex.Matches MatchCollection?
Mar 5, 2009I've been working on this RegEx for the past day or so and I think I have it worked out so that it returns the data I want. First a little background.I have a content editor that users will be able to edit web pages. They can format text, add links, etc.. standard content editor stuff. When they click save, the editor provides the ability to get the content (editor.Content) and put it into a string. What I want to do is get any links (<a> tags) and find out if they are internal or external links and if they are PDF files.
Here is the Expression I've come up with:
<a[^<>]*hrefs*=s*[""'](?<domain>https?://[^/s'""]*)*/?(?<path>/?[^s""]+?)?[[>""']
With this, I am able to separate the domain (if it has one) and the path out. Then, I loop through the matches...
dim matchColl as MatchCollection = Regex.Matches(editorContent, regExString)
For Each m as Match in matchColl
If m.Groups("domain").value <> myInternalDomain and m.Groups("domain").value <> "" then
'this is an external domain... do some stuff
[code]....
My question is this... the parts where I 'do some stuff' to the values, what would be the best way to get that back into my 'editorContent' string? I could probably put the editorContent into a StringBuilder and do a whole bunch of replaces on it, but is that very efficient?So, for example, with the PDF, I want to specify that it open in a new window (target="_blank") and for the external URL, add some javascript code into the onclick attribute.

Replace Comma In String But Only At Specific Position
Dec 12, 2011I am reading a csv file in VB.net and saving the line to a SQL database. At a later point in my code, the SQL line is retrieved in the application, and the Split function is used to get 'field' values. The Split is done taking comma as the separator. The application processes many other files (including excel), and the split function is used for all of them. The problem I am now facing is that one of the csv files I read, has a field value that starts with " followed by multiple values separated by a comma and ends with another ". The normal reading of the csv file results in each of those single field values is taken to be a separate value.
An example line is:
Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
Where there should only be separated to 4 columns, they get separated to 9 columns instead. What I want to do is replaced the commas after 'Bus' and until 'Toll' with a '?' instead. I have tried using Replace, including the overloaded one with starting position, but it ends up replacing ALL the commas in the line with '?'
Attempt 1:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine(intStartPos), ",", "?")
end if
Where vstrLine is Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
and intStartPos is the first instance of a comma after the "
It returns only the '?' and not the string with 1 comma replaced by '?'
Attempt 2:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine, ",", "?", intStartPos)
end if
It returns a string with all commas replaced with '?'
Concatenating A Variable With A Regex Group Match In Regex.replace?
Apr 5, 2012I 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?
