First off, rolling your own regexp to parse URLs is a terrible idea. You must imagine this is a common enough problem that someone has written, debugged and tested a library for it, according to the RFCs. URIs are complex – check out the code for URL parsing in Node.js and the Wikipedia page on … Read more
Usually a back-reference is either $1 or \1 (backslash one) for the first capture group (the first match of a pattern in parentheses), and indeed Sublime supports both syntaxes. So try: my name used to be \1 or my name used to be $1 Also note that your original capture pattern: my name is (\w)+ … Read more
Assuming you want the whole regex to ignore case, you should look for the i flag. Nearly all regex engines support it: /G[a-b].*/i string.match(“G[a-b].*”, “i”) Check the documentation for your language/platform/tool to find how the matching modes are specified. If you want only part of the regex to be case insensitive (as my original answer … Read more
Pass re.IGNORECASE to the flags param of search, match, or sub: re.search(‘test’, ‘TeSt’, re.IGNORECASE) re.match(‘test’, ‘TeSt’, re.IGNORECASE) re.sub(‘test’, ‘xxxx’, ‘Testing’, flags=re.IGNORECASE)
For this specific example, var thenum = thestring.replace( /^\D+/g, ”); // replace all leading non-digits with nothing in the general case: thenum = “foo3bar5”.match(/\d+/)[0] // “3” Since this answer gained popularity for some reason, here’s a bonus: regex generator. function getre(str, num) { if(str === num) return ‘nice try’; var res = [/^\D+/g,/\D+$/g,/^\D+|\D+$/g,/\D+/g,/\D.*/g, /.*\D/g,/^\D+|\D.*$/g,/.*\D(?=\d)|\D+$/g]; for(var … Read more
str.replace() v2|v3 does not recognize regular expressions. To perform a substitution using a regular expression, use re.sub() v2|v3. For example: import re line = re.sub( r”(?i)^.*interfaceOpDataFile.*$”, “interfaceOpDataFile %s” % fileIn, line ) In a loop, it would be better to compile the regular expression first: import re regex = re.compile(r”^.*interfaceOpDataFile.*$”, re.IGNORECASE) for line in some_file: … Read more
Try this: ((.|\n)*)<FooBar> It basically says “any character or a newline” repeated zero or more times.
Use a character set: [a-zA-Z] matches one letter from A–Z in lowercase and uppercase. [a-zA-Z]+ matches one or more letters and ^[a-zA-Z]+$ matches only strings that consist of one or more letters only (^ and $ mark the begin and end of a string respectively). If you want to match other letters than A–Z, you … Read more
Instead of .* use .\{-}. %s/style=”.\{-}”//g Also, see :help non-greedy
I like to use: myString = Regex.Replace(myString, @”\s+”, ” “); Since it will catch runs of any kind of whitespace (e.g. tabs, newlines, etc.) and replace them with a single space.
