C# - How To Write A Multi-line RegEx Expression
Jan 12, 2010I have a vb.net class that cleans some html before emailing the results.
Here is a sample of some html I need to remove:
<div class="RemoveThis">
Blah blah blah<br />
Blah blah blah<br />
[Code]...
I am already using RegEx to do most of my work now. What would the RegEx expression look like to replace the block above with nothing?
I tried the following, but something is wrong:
'html has all of my text
html = Regex.Replace(html, "<div.*?class=""RemoveThis"">.*?</div>", "", RegexOptions.IgnoreCase)
C# - Regex To Remove Single-line SQL Comments?
Mar 23, 2012give me a working regex expression (C#/VB.NET) that can remove single line comments from a SQL statement ?I mean these comments:
-- This is a comment
not those
/* this is a comment */
because I already can handle the star comments.I have a made a little parser that removes those comments when they are at the start of the line, but they can also be somewhere after code or worse, in a SQL-string 'hello --Test -- World' Those comments should also be removed (except those in a SQL string of course - if possible).Surprisingly I didn't got the regex working. I would have assumed the star comments to be more difficult, but actually, they aren't.
As per request, here my code to remove /**/-style comments (In order to have it ignore SQL-Style strings, you have to subsitute strings with a uniqueidentifier (i used 4 concated), then apply the comment-removal, then apply string-backsubstitution.
static string RemoveCstyleComments(string strInput)
{
string strPattern = @"/[*][wds]+[*]/";
//strPattern = @"/*.*?*/"; // Doesn't work

Splitting A CSV File Line Array Using Regex
Jan 5, 2011I used to do a bit of coding in early versions of VB years ago but moved on to things like RPG400, CL and SQL on an AS/400 box. As I am no longer in this career, I havent touched an AS/400 for a while either.
I am currently working on a visual basic console application in Visual Studio 2005 which takes various csv files from an osCommerce web shop, processes them and writes the data to TAS Books accounts software with the aid of the Infoplex COM module.
I have 2 functions, one reads each line of a csv file into an array, and the second function uses Regex to split the lines array into the various fields before they are added to a structure.
There are something like 5000 records (lines) in the csv file, one example is as follows;
[Code]...
My problem is that due to the formatting of the product description in the example csv line above, it fails the Regex match and therefore fails to read.
I know this is because my pattern is wrong, but I'm not sure how to solve it, I think all I really need is for Regex to split the line by the "," between each element, this might be a little difficult because some of the descriptions contain both , and " but never one after the other.

VS 2008 Regex Designer - Show The User The File - Allow Them To Select A Line To Match And / Or Extract From
Aug 23, 2010This may take some explaining but the concept is pretty simple. A user will select a file which contains data that they wish to extract from, so keeping it simple they pick a file like so:
[Code]....
So, I need to show the user the file, allow them to select a line to match and/or extract from. So they select the first line ready for a match, they then select a word/s to mark as a constant for matching, so in this case it would be: MyGroup A simple version for text match would be like "MyGroup *" Now, I need to convert this to regex dynamically (I assume its the best method), its not a one off, the data that is selected is all open and up to user selection. There could be multiple selections and multiple extractions on the same line!

Parsing Multi-line Clipboard Text Into A Single Line And Pasting Into A Textbox?
Feb 7, 2011a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
