This sort of example for extracting integers from a string is common: string input = "10 blah 20 30 nonsense 40 50"; string[] numbers = System.Text.RegularExpressions.Regex.Split(input, @"^[\d]"); But how can I account for numbers with a decimal point? e.g. string input = "10 blah 20 30 nonsense 40.5 50" used with the above regul...

Hi, I'm trying to use regex to parse some plain text and add a definition from a glossary to any words that match it. I'm doing it like this: for ( $i = 0; $i < count($terms); $i++ ) { $search = '|(?<=\b)('.preg_quote($terms[$i]['title']).')(?=\b)|i'; $replace = '<a class="tt2" rel="tooltip" title="'.$terms[$i]['pageBody'].'">...

For example if the table contains the following data: -- ID, Address -- | 1, "Test1" | | ...

The first two I've done, but I'm having a hard time matching if it's the first character in a string.

Yes, I know, I know, parsing HTML with regular expressions is very bad. But I am working with legacy code that is supposed to extract all link and style elements from a html page. I would change it and use the dom extension instead, but after the regex there is a huge code block which relies on the way preg_match_all returns the matched ...

case 1: IN: example.com?p1=val1&p2=val2&p3=val3 OUT: example2.com?p1=val1&p2=val2&p3=val3&p4=val4 -- p4=val4 was added to the end, the rest of the parameters were preserved case 2: IN: example.com?p1=val1&p4=badvalue OUT: example2.com?p1=val1&p4=goodvalue -- the value of p4 was changed, so we need to scan for the existence of the ...
I have an application that accepts an address and writes it to the db. I then want to take that address and convert it to something I can send through Google Maps, so I need to replace all the spaces with "+" symbols. I understand how to do that with a regex: address.gsub(/\s/, "+") And can create a variable that does it, voila. But I...
I'm currently trying to learn regular expressions with some simple "real world" examples. Take in consideration the following string: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9.2a1pre) Gecko I want to find the RV value (1.9.2a1pre). I need to apply the following rules: RV: can be in any case (RV, rv, rV, Rv...). RV...
For some reason, I can't seem to find a good answer for this one. I have been trying to escape out the caret (\^), and to use the hex, octal, and other codes for the character using \xdd, \dddd, etc... But my replace regexp won't replace the caret (^) with anything. It seems to simply break the expression. Here is the code I am using:...
I wrote this validation method but am having issues with it. function validate_password(pwd) { var score = 0; // Min length is 8 if (pwd.length<8) return false; // Is lower present? if (/[a-z]/g.test(pwd)) { console.log('a-z test on "'+pwd+'":' + /[a-z]+/g.test(pwd)); score++; } ...
Hi. I'm a bit confused about different regex formats.
