Regular Expression to Match


Here is the kind of text I want to match via a regular Expression

The id="dgSchedule" is always present in the TAG but its location may differ

The table is span over multiple line/contains white spaces/tabs...

I have the regular expression to match the start and end tag respectively over a single line

\<table .*\>


The problem is to match the whole table span over multiple lines

<table cellspacing="0" rules="all" border="1" id="dgSchedule" style="border-style:None;height:100%;width:100%;border-collapse:collapse;">
	<tr class="blackbar" align="center" style="background-color:#7FB4DE;font-family:Verdana;font-weight:bold;height:20px;">
		<td>From Place</td><td>To Place</td><td>Time</td><td>Bus Type</td>

	</tr><tr style="background-color:#DEECF5;">
	</tr><tr style="background-color:#EFF5FA;">
	</tr><tr style="background-color:#DEECF5;">

Problem Excluding Section In Quotes From Regular Expression Match


Hi There,

Currently I have the string:

"WHERE Column_1_Name = 1 AND Column_2_Name = 'Test Column Criteria'"

& my desired matches are as follows:




However, so far, I can only achieve

'Test Column Criteria'

via: (([a-z][\w]+)|('[\w ]+'))(?!('[\w ]+'))




via (('[\w ]+')|([a-z][\w]+))(?<=\3)


All help appreciated much appreciated.

(I'm using the .net engine, case insensitive)

Can we use regular expression to match numbers not preceded by a specified set of characters


I have been trying to come up with a RegEx that would match numbers (including decimals and negative numbers) that are not preceded by a specified set of characters. For example:

Specified set of characters (not including comma): c, t

Input string: “This c2 is one element. And t-4a, d25, c2.54, v4.28, q58 are other elements”

Desired result (the numbers not preceded by c and t):

The pattern I tried: [^ct](-?\d+\.?\d*|\.\d+)

The matches I got (Note: I fetched the results from Group 1):


I don’t want the numbers in bold to be returned since in t-4a the integer -4 is preceded by t, and in c2.54, 2.54 is preceded by c.

Can we refine the above pattern or is it even possible?

Thank you.

Regex regAppDH = new Regex(@"/String1/String2/String3/stirng4(\[[0-9]|[1-9][0-9]\])/string5/stirng6\[[0-9]|[1-9][0-9]\]")

Need a regular expression


I have a required field validator for a texbox, but I just found out that the texbox can have a space in it (for a delimiter, let's say).

I checked the .net and regexlib.com, but couldn't find what I was looking for.

I simply need a regular expression that basically excepts any character string including spaces in it or even a space by itself

Can someone help me out?

Matching set of characters via regular expression

I need to be able to match sets of quote and space characters in a string and replace these accordingly. I currently have this done in 2 lines of code, but would like to use regular expression so that I can use only 1 line of code. See below: var Qt = unescape("%22"); //quote char var Sp = unescape("%20"); //space var Cr = unescape("%0d"); //carriage return var Lf = unescape("%0a"); //line feed var CrLf = Cr + Lf;  //carriage return & line feed stringOut = stringIn.replace(Qt+Qt+Sp+Qt,Qt+Qt+CrLf+Qt); stringOut = stringOut.replace(Qt+Qt+Sp+Qt+Qt,Qt+Qt+CrLf+Qt+Qt);   I want to replace space in string like in pattern below with carriage return line feed: (in hex) 22 22 20 22 or 22 22 20 22 22. This needs to return 22 22 0D 0A 22 or 22 22 0D 0A 22 22   Line in green above will only match and replace 22 22 20 22 , but I want have regular expression into 1 line of code which  will match and replace either 22 22 20 22 or 22 22 20 22 22

Need a Specific Regular Expression

I am clueless when it comes to building regular expressions. I know what they are, but haven't been able to master them. I found this regular expression which will validate a Sprint/Nextel Direct Connect number - all numbers, only asterisks allowed. ^\d+\*\d+\*\d+$ http://www.regexlib.com/REDetails.aspx?regexp_id=1730 Can someone modify it for me so that it checks for a minimum and maximum number of numbers in the string and checks that there are (2) asterisks? If you can use a minimum of (6) and a maximum of (12), I should be able to figure out how to modify it myself after I call Sprint on Monday.  David H
