Sorry, I am not a reg expert. I would like to ask for help how to take certain words out of a string.
Here is a example, I have a long string like this:
[SubClassOf(<file:F:/Projects/OIL/DAMLOilEd/ontologies/ka.daml#Lecturer> <file:F:/Projects/OIL/DAMLOilEd/ontologies/ka.daml#Person>)]
I need to extract the words Lecturer and Person out of the long string. The reg will perform something like start with # and end with >.
For anything between # and >:
'(?<=#)[^#>]*(?=>)'
This will match everything (excluding # and >) inside #> and the result won't include the # and > at starting and ending.
Put dot and / inside a character class so that it would match .png or /png strings. var imageReg = /[\/.](gif|jpg|jpeg|tiff|png)$/i; Your regex would return true if there is a dot exists before png but here there exists a forward slash , so it fails....
Just get the dot outside of the captruing group and then make it as optional. @"[+-]?\d+\.?\d*" Use anchors if necessary. @"^[+-]?\d+\.?\d*$" ...
Use \d+ to match one or more digits. \b(?:http:\/\/)?(?:www\.)?example\.com\/g\/(\d+)\/\w put http:// and www. inside a capturing or non-caturing group and then make it as optional by adding ? quantifier next to that group. For both http and https, it would be (?:https?:\/\/)? DEMO...

You are trying to write a python code using ruby syntax. This is not a best approach to GTD. Slashes are handled right-to-left, yielding not what you expected. As soon as one finds herself putting three or more backslashes inside the string, she should admit, she’s doing it wrong. At...
To only allow digits, comma and spaces, you need to remove (, ) and -.

Use {} instead of () because {} are not used in XPath expressions and therefore you will not have confusions.

You turn off case sensitivity using an i inline flag in regex: (?i)https?:\\/.* See Foundation Framework Reference for more information on available regex features. (?ismwx-ismwx) Flag settings.

Could not figure out a regex solution, but here's a non-regex solution. It involves parsing numbers (not in curly braces) before each comma (unless its the last number in the string) and parsing strings (in curly braces) until the closing curly brace of the group is found. If regex solution...

At least, you can rely on the tag names and text, navigating the DOM tree horizontally - going sideways. These are all strong, p and span (with id attribute set) tags you are showing. For example, you can get the strong text and get the following sibling: >>> from bs4...

Using sqlite3 from bash on OS X seems fairly straightforward (I'm no expert at this, by the way). You will need to find out which table you need. You can do this with an interactive session.

You can use the regex in a negative look-ahead and then add a \w shorthand class to match alphanumeric symbols, or [a-zA-Z] with \b word boundaries: (?![0-9-+*/()x]|abs|pow|ln|pi|e|a?(?:sin|cos|tan)h?)\b[a-zA-Z]+\b See regex demo Since we are only allowing letters with [a-zA-Z], we can reduce this further to (?!x|abs|pow|ln|pi|e|a?(?:sin|cos|tan)h?)\b[a-zA-Z]+\b See another demo...
I would try with: Pattern regex = Pattern.compile("(?<= )\\d(\\d*[,\\.]?\\d+)*(?=[ .]?sq)"); where: (?<= ) - there is space before \d - starts with digit (\d*[,\.]?\d+)* - next is digit or digits, there could be comma or point with more digits - and it can repeats like in 100,000,000 (?=[ .]?sq) -...
A work-around for the lack of variable-length lookbehind is available in situations when your strings have a relatively small fixed upper limit on their length. For example, if you know that strings are at most 100 characters long, you could use {0,100} in place of * or {1,100} in place...
Use the alternation with $: import re mystr = 'HelloWorldToYou' pat = re.compile(r'([A-Z][a-z]*)') # or your version with `.*?`: pat = re.compile(r'([A-Z].*?)(?=[A-Z]+|$)') print pat.findall(mystr) See IDEONE demo Output: ['Hello', 'World', 'To', 'You'] Regex explanation: ([A-Z][a-z]*) - A capturing group that matches [A-Z] a capital English letter followed by [a-z]* -...
A variant of n-dru pattern since you don't need to describe all the string: SELECT '#hellowomanclothing' REGEXP '(^#.|[^o]|[^w]o)man'; Note: if a tag contains 'man' and 'woman' this pattern will return 1. If you don't want that Gordon Linoff solution is what you are looking for....

There's a bug in your code. As a string is immutable in JavaScript, replace doesn't change it but returns a new one.

In order to match the string with a literal backlash, you need to double-escape it in a raw string, e.g.: re.search(r'@CAD_DTA\\">(.+?)@[email protected]@CAD_LBL',result.text) ^ ^ In order to get the index of the found match, you can use start([group]) of re.MatchObject IDEONE demo: import re obj = re.search(r'@CAD_DTA\\">(.+?)@[email protected]@CAD_LBL', 'Some text [email protected]_DTA\\">I WANT...
I don't understand why it would give me two hellos back? Because the first entry in the array is the overall match for the expression, which is then followed by the content of any capture groups the expression defines. Since the expression defines one capture group, you get back...
The quotes are an issue but not the issue you are running into when you escape them. Your delimiter is terminating your regex just before the closing a which is giving you the unknown modifier error. It appears you don't have error reporting on though so you aren't seeing that....
Updated: This will check for the existence of a sentence followed by special characters. It returns false if there are no special characters, and your original sentence is in capture group 1.

What you're looking for is called a character class. A character class is a group of characters that you're saying can be matched at that position in the string. To make a character class you enclose your list of matchable characters in square brackets, like this: [.,:;!?] This will match...
Some notes about your original regex: a lookahead only makes sense at the end of the string; you were probably looking for a non-capturing group, e.g. T(?:P-) instead of T(?=P-), but you don't even need those if they appear exactly once (i.e. if there's no need to put a *,...
This is one way to do it, using preg_match: $string ="SomeStringExample"; preg_match('/^[b-df-hj-np-tv-z]*/i', $string, $matches); $count = strlen($matches[0]); The regular expression matches zero or more (*) case-insensitive (/i) consonants [b-df-hj-np-tv-z] at the beginning (^) of the string and stores the matched content in the $matches array. Then it's just a matter...
You can make use of the multiline flag, and ^ and $ anchors that will match at the string start and string end repsectively: (?m)^.*lonfksa\.newsvine\.com.*$ Mind that you need to escape a dot in regex to make it match a literal dot. Your regex (?s)lonfksa.newsvine.com(?s) contains unescaped dots that match...

You could convert this to a slightly more maintainable format, without getting into regular expressions. This is one way to use an array to accomplish your goal: // Super-quick one-liner: var str = '2042038423408'; var matchCount = $.grep(['12', '23', '34', '45', '56', '67', '78', '89', '90', '01'], function(num, i) {...

The pattern attribute has to match the entire string. Assertions check for a match, but do not count towards the total match length. Changing the second assertion to \w+ will make the pattern match the entire string. You can also skip the implied ^, leaving you with just: <input pattern="(?!34)\w+"...
