Hello there,
I need some clever regular expression writing in IIS7 to redirect traffic from one site to another, the pages are similar in structure but information needs re-writing.
Here's an example:
http://www.mysite.com/manufacturers/Name_of_Manufacturer_6828/Name_OF_Product_43146.htm
needs to be structured as the following
http://www.newsite.co.in/free-msds-download/name-of-manufacturer/name-of-product/
Here's what needs changing:
1). Only Alpha, Numeric and hyphen's allowed.
2). Change '_' to '-'.
3). Remove the '_NUMBER' directly after the manufacturer name and before the '/'.
4). Remove the '_NUMBER' directly after the product name and before the '.htm'.
5). Remove the '.htm' and replace with a '/'.
It needs writing into the code below please as a permanent 301 redirect:

Hi,
You can use the JavaScript below,
var str="http://www.mysite.com/manufacturers/Name_of_Manufacturer_6828/Name_OF_Product_43146.htm";
str=str.replace("http://www.mysite.com/manufacturers/", "");
var key=str.split("/");
var manufacturer=key[0];
var product=key[1];
var to_index=manufacturer.lastIndexOf("_", manufacturer.length);
manufacturer=manufacturer.substring(0, to_index);
manufacturer=manufacturer.replace(/_/gi, "-");
product=product.replace(/.htm/gi, "");
to_index=product.lastIndexOf("_", product.length);
product=product.substring(0, to_index);
product=product.replace(/_/gi, "-");
var cleanUrl="http://www.newsite.co.in/free-msds-download/"+manufacturer+"/"+product+"/";
document.write(cleanUrl);
variable cleanUrl holds the url you are looking for.Hope this will help.

I am going to make a few assumptions. Since you said this is in IIS, you probably can't create .Net or JavaScript code to handle the redirect (i.e., all redirects must be done using some regexes in a configuration file). Also, I assume the number of underscores in the "mysite.com" URL is variable.
I don't think you can do this with one redirect, but you can create several. For example, you can start off with these (create more to handle more underscores):
^http://www\.mysite\.com/manufacturers/(?<MAN>[a-z0-9]+)_[0-9]+/(?<PRO>[a-z9-9]+)_[0-9]+\.htm$
http://www\.newsite\.co\.in/free-msds-download/${MAN}/${PRO}/
^http://www\.mysite\.com/manufacturers/(?<MAN1>[a-z0-9]+)_(?<MAN2>[a-z0-9]+)_[0-9]+/(?<PRO>[a-z0-9]+)_[0-9]+\.htm$
http://www\.newsite\.co\.in/free-msds-download/${MAN1}-${MAN2}/${PRO}/
^http://www\.mysite\.com/manufacturers/(?<MAN>[a-z0-9]+)_[0-9]+/(?<PRO1>[a-z9-9]+)_(?<PRO2>[a-z9-9]+)_[0-9]+\.htm$
http://www\.newsite\.co\.in/free-msds-download/${MAN}/${PRO1}-${PRO2}/
^http://www\.mysite\.com/manufacturers/(?<MAN1>[a-z0-9]+)_(?<MAN1>[a-z0-9]+)_[0-9]+/(?<PRO1>[a-z9-9]+)_(?<PRO2>[a-z9-9]+)_[0-9]+\.htm$
http://www\.newsite\.co\.in/free-msds-download/${MAN1}-${MAN2}/${PRO1}-${PRO2}/
That is simple enough, but that could end up being a lot of rules if you have a large range of underscores (e.g., "the_name_of_some_long_product" and "the_name_of_some_long_manufacturer"). Alternatively, you can redirect all of the "mysite" URL's that match the pattern you want to a single URL on "newsite" that takes the original URL as a query string. The page on newsite can then parse the query string and perform a redirect using C# or VB.Net code, which gives you more flexibility than a configuration file.
Note: the above regexes are untested and may contain mistakes, but you get the idea.

I need to check whether password has at least 6 characters with at least 1 letter and one special character. I am checking the condition !Regex.IsMatch(strPassword,"(?!^[0-9]*$)(?!^[a-zA-Z]*$)^([a-zA-Z0-9]{6,24})$"). But it doesnot allow special character.
I need to change the expression to check if there is at least one special character.
Please help me out.

|
|

^(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[^a-zA-Z0-9]).{6,}$
- ^ checks for the start of the input string.
- (?=.*[a-zA-Z]) checks that there are at least one letter.
- (?=.*[0-9]) checks that there are at least one digit.
- (?=.*[^a-zA-Z0-9]) checks that there are at least one special character (not a letter nor digit).
- .{6,} checks that there are at least 6 characters.
- $ checks for the end if the input string.

I need help with regular expression for a javascript I'm working on.
I have some html code into a variable that is named xmlDoc. The string includes a table and there are some things there that I want to pick out with regex.
<tr class="myGreyRow">
<td>6</td>
<td id="fn1">Prentice, Bob</td>
<td>340584305858</td>
<td>Logged out</td>
<td>
<a class="listlink" href="javascript:doEditAgent("56746")">Edit</a>,
<a class="listlink" href="javascript:doRemoveAgent("56746", "fn1")">Delete</a>,
<a class="listlink" href="javascript:doLoginLogout("4", "56746","fn1")">Log in</a>
</td>
</tr>
In this code I want to pick out:
1. The name, "Prentice, Bob"
2. The status, "Logged out"
3. The content from doLoginLogout(), "4", "56746","fn1"
What pattern(s) should I use?
There are five rows similar to this in the table that I need to do this on.

Hi Everyone,
I am trying to figure out how to parse html line and take from it the $ sign and a the monetary value.
For example:
The price of the book is $15.00 and the price of the computer is $1,299.99 cents.
Thank you.

\$(\d{1,3}(,\d{3})*)(\.\d\d)?

Thanks for the reply. I doesn't seem to work.
Can you explain briefly what you are attempting to match with that expression?
Thank you.

It does work. Try this in a console app:
static void Main(string[] args)
{
Regex rx = new Regex(@"\$(\d{1,3}(,\d{3})*)(\.\d\d)?");
foreach (Match m in rx.Matches("This matches $4.12 dollars. It also matches $32.32 or $15 or $2.11 or $0.12 or $156,789.33 or $12,345.67"))
{
Console.WriteLine(m.Value);
}
Console.ReadKey();
}
Output:
$4.12
$32.32
$15
$2.11
$0.12
$156,789.33
$12,345.67
Of course, you must reference the System.Text.RegularExpressions namespace. Also, here is a page you can use to help learn regular expression syntax:

Thank you for the sample and the link. It works.

I ran that Regex against your test case and it works perfectly. What output are you getting? What does your code look like that's calling it?

In general it isn't a good idea to parse html/xml via regular expressions.
Instead one should use a html/xml parser.
One might use regex if all of the following is true.
1. The source(s) for html/xml are limited. Thus for example there is only one source and there is unlikely to be another.
2. The source is machine generated (thus a library was used to create it rather than an adhoc code of some sort.)
The reason this isn't a good idea is because there are many variations in the way html/xml can be formatted. By the time one has accounted for all of those variances either one has a parser or one has a maintenance problem (or maintenance nightmare).

Hi Guys,
I have three Regex and would like to know if it's possible to combine them into one.
I'm validating phone numbers in the form:
- 0219081234
- 021 908 1234
- 021-908-1234
here are my regex for the above in order:
- var phoneRegex1 = /^(\d{3})(\d{3})(\d{4})$/;
- var phoneRegex2 = /^(\d{3})(\-)(\d{3})(\-)(\d{4})$/;
- var phoneRegex3 = /^(\d{3})(\ )(\d{3})(\ )(\d{4})$/;
Thanks in Advance,
Morgs

Just use ? operator
Like this:
^\d{3}-?\s?\d{3}-?\s?\d{4}$
You can flame me whichever way you want and I wouldn't care a bit.
But if you group me with some idiots, I'll turn into your worst nightmare.

Thanks a ton Firo,
will give it a try...

I think that would match values like:
123456-7890
123456 7890
123456- 7890
123-4567890
123-456 7890
123-456- 7890
123 4567890
123 456-7890
123 456- 7890
123- 4567890
123- 456-7890
123- 456 7890
123- 456- 7890
Which are not in his spec.

If you want to ensure that the separators (if any) between the groups are the same, I think you need to use a backreference[^].
Something like this perhaps:
(?'Area'\d{3})(?(?=(\s|-))(?'Sep'(\s|-)))(?'Prefix'\d{3})(?(Sep)\k<Sep>)(?'Number'\d{4})

I think this is what you need.
^\d{3}(-|\s)?\d{3}(-|\s)?\d{4}$
|
|
|
|
|
Have a look at this pattern:
^\d{3}[\s-]?\d{3}[\s-]?\d{4}$

I'm looking for a regex which can match the a value between brackets and deal with a seperator character within.
This is the format I'm after:
[?#?]
where ? can be one or more characters and # is '+', '-' or '='
It should match the following.
[1+1]
[A=T]
[AB=#1#2#3]
So far I've got this:
\[.*[\+-=]?\]
But it doesn't work well, it includes text between the 'tags'.
[A=B]ShouldNotInclude[1=3] (but it does )
I'm obviously doing something wrong,the whole regex probably.
Anyone got an idea?
Found the problem, not the solution.
Problem is that it jumps to the last ']' character it can detect.

Got it:
\[(.*?)[\+-=](.*?)\]

What you saw is called 'greedy' matching. The better regex engines support non-greedy matching operators, which behave a bit more intuitively, even if they make the regex unreadable!
