Multiple Regex Replacements In C#?
Nov 10, 2010
I am trying create a Regex-based replacement for an article to automatically convert embedded references (many of them) in posts into the appropriate link and title format.
For example, given this:
I have already blogged about this topic ((MY TOPIC ID: "2324" "a number of times")) before. And I have also covered ((MY TOPIC ID: "777" "similar topics")) in the past.
... I want to get this:
I have already blogged about this topic <a href='/post/2324'>a number of times</a> before. And I have also covered <a href='/post/777'>similar topics</a> in the past.
I currently have this:
/* Does not work */
public static string ReplaceArticleTextWithProductLinks(string input)
{
string pattern = "\(\(MY TOPIC ID: \".*?\" \".*?\"\)\)";
string replacement = "<a href='/post/$1'>$2</a>";
return Regex.Replace(input, pattern, replacement);
}
But it seems to return lines that contain <a href='/post/'></a> without appending matches instead of $1 and $2.
Question: What is the easiest way to do convert the string #1 above to string #2 above?

YARPQ - Yet Another Regex Pattern Question:
What I am trying to figure out is how to use a custom delimiter, single character or set of characters, to wrap a block of text inside a larger body of text and then pull that text out via regex. I have successfully done this with a single instance of wrapped text. If I have multiple instances, it blows up. Here is an example.
This would be my text block with the internally wrapped text:
[Code]....
When my current regex runs on this block, the greedy nature gives me a match starting with my first wrapped block delimeter and ending with my second wrapped block end delimeter. So my regex of @"#Delim(.*)#EndDelim" doesn't work in this instance. I am trying to figure out how to exclude the #EndDelim from my grouping. Simply using ([^#EndDelim]*) doesn't work as it tells regex to ignore the individual characters inside the brackets and not the actual word so this breaks if I have any of those characters inside my wrapped block of text.
I am probably making this harder than it needs to be. Does anyone know of a good solution or how to ignore entire words in regex?

I've tried to do my homework on this...
I'm migrating a site from classic asp to asp.net 4.0
Before I rework all the code, I wanted to get clarification that the way i think my database code should be updated is fairly correct. (I'm using SQLClient objects)
First, when old code would use forward only recordsets or access single record/value, I'm fairly sure i'd use SqlCommand and SqlDataReader. That is pretty straightforward.
Now, when my old code navigates a recordset (movePrevious, find, etc.)... I believe the way to go is with SqlDataAdapter and DataTable to retrieve the data and DataView to filter/find/navigate the data.
I'n looking to do a quick migration... i don't want to get too bogged down in the new entity framework... so - just trying to stick with similar objects/logic.
I know this is one of those questions that doesn't really have a right/wrong answer... and I think that is part of my problem in finding an answer - there are so many.

using asp.net 4 we do a lot of Word merges at work. rather than using the complicated conditional statements of Word i want to embed my own syntax. something like:
Dear Mr. { select lastname from users where userid = 7 },
Your invoice for this quarter is: ${ select amount from invoices where userid = 7 }.......
ideally, i'd like this to get turned into: string.Format("Dear Mr. {0}, Your invoice for this quarter is: ${1}", sqlEval[0], sqlEval[1]);

I have a dummy html file:
.....<body>
<p><a href="http://www.google.com">link 1</a></p>
<p><a href="http://www.google.com">link 2</a></p>
<p><a href="http://www.google.com">link 3</a></p>
<p> </p>
</body>
I need to add a autoincrement int after the http://www.google.com, though unique for each occurance so the result will be:
<body>
<p><a href="http://www.google.com" 1>link 1</a></p>
<p><a href="http://www.google.com" 2>link 2</a></p>
<p><a href="http://www.google.com" 3>link 3</a></p>
<p> </p>
</body>
Obviously with .replace I get [URL] 3 2 1 > 1 and so on... I am thinking of contructing a two dimensional Array where myArray[0][0] will be the first match like myArray[URL][0] the second element the second match. myArray[URL][1] and so on. So then I would iterate through the second dimension of the array. Will this work? I am thinking that it won't...

i have an requirment where an user can enter multiple email address.
The validation should ensure that he should enter address in the format "something@abc.com".
my existing validation ensures that some text is entered before "@" symbol and "abc.com" is the domain.
@"w+([-+.']w+)*@abc.com$";
I would need my regex to check for the delimiter ";" between two mail id's .
valid: a@abc.com |
a@abc.com;b@abc.com|
invalid: a@abc.comm | a@abc.com,b@abc.com | @abc.com |
a@abc.comb@abc.com|
I've tried many links but ther were of no use and i'd be grateful if someone could help me modify the current one to suit my requirments

I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.
I was trying to follow this tutorial on msdn, but it doesn't quite fit perfectly with my problem:
[URL]
Code:

In my asp.net application i have url [URL] to match it i have regex
"~/(.+)" which works perfectly fine. But if i navigate to www.site.com/login.aspx again regex matches with this expression "/(.+)".
In Simple words i want a regex which only match the extenionless url. IF extension is present in the url then do not match it
<RewriterRule>
<LookFor>~/(.+)/(.+)/(.+)/</LookFor>
<SendTo>~/Shop/Item.aspx?cn=&1&it=$2&ft=$3</SendTo>
</RewriterRule>

I try to replace [h2] to <h2> I use this coding:
string o = "<h2>test</h2>";
o = Regex.Replace(o, "[h2]", "<h2>");
o = Regex.Replace(o, "[/h2]", "</h2>");
But the result after the first regex is:

with a regex that would replace the following. The only thing that would remain the same is the div tags, the id's and classes could change and so could the content.
<div id="nav" class="whatever">Content is whatever</div>

string lNewHTML = Regex.Replace(lOldHTML, "(word1|word2|word3)", "<a href="page.aspx#$1">$1</a>", RegexOptions.IgnoreCase);
The code works, but I need to include some exceptions to the replace - e.g. I will not replace anything i an img-, li- and a-tag (including link-text and attributes like href and title) but still allow replacements in p-, td- and div-tags.

How do I solve the problem below? I'm creating a simple content management system, where there is a HTML template with specific markup that denotes where content should be:
<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>
Separate from this, there is content in a database field that looks a little like this:
<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test text<!-- #EndEditable -->
As you can guess I need to merge the two, that is, replacing
<!-- #Editable "Body1" -->
with: This is Test Text. I've begun the code here. But I'm having problems using the Regex Replace function that should be located at the very bottom of that For/Each.
//Html Template
string html = "<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>";
//Regions that need to be put in the Html Template
string regions = "<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test #EndEditable -->";
//Create a Regex to only extract what's between the 'Body' tag
Regex oRegex = new Regex("<body.*?>(.*?)</body>", RegexOptions.Multiline);
//Get only the 'Body' of the html template
string body = oRegex.Match(html).Groups[1].Value.ToString();
// Regex to find sections inside the 'Body' that need replacing with what's in the string 'regions'
Regex oRegex1 = new Regex("<!-- #Editable "(.*?)"[^>]*>",RegexOptions.Multiline);
MatchCollection matches = oRegex1.Matches(body);
// Locate section titles i.e. Body1, Extra
foreach (Match match in matches)
{
string title = oRegex1.Match(match.ToString()).Groups[1].ToString();
Regex oRegex2 = new Regex("<!-- #BeginEditable "" + title + ""[^>]*>(.*?)<!-- #EndEditable [^>]*>", RegexOptions.Multiline);
//
//
// Replace the 'Body' sections with whats in the 'regions' string cross referencing the titles i.e. Body1, Extra
//
//
//

I am currently using this regex to get the page number from the url:
@"/(d+)$";
Which worked fine for urls like:
/some_category/2
/some_category2/323
My urls now have some additional querystring values (optionally), so the current regex is not working for these cases.
So now I need a regex to support:
/some_category/2
/some_category2/323
/some_category2/323?a=1&b=2
/some_category2/323?&c=123&a=1&b=2
I am using a route with wildcards so I can use the built in asp.net mvc for this.

Do I need to use RegularExpressionValidator?
More over, I also need to validate the credit card number, I found a few RegularExpressions for that in the net but each one is different from the other and I am not sure which one to use.. Does anyone know od a working expression that will suit all credit cards?
