Couple of questions. What regex flavor are you using POSIX, PCRE, .NET, Java, etc?
Is this part of a compiled/interpreted program (e.g C++, C#, python), or is it part of something more like a shell script?
I'm trying to use it within Pabbly Connect, which is an integration system like Zapier or Make. I can use the following spreadsheet type formulas found here https://www.pabbly.com/spreadsheet-formulas/ and similar usually to Google sheet formulas.
it doesn't work well when there's a street direction afterwards like "123 Easy Street N"
Your pattern explicitly requires at least two letters at the end of the line, with a non-word character before them. "123 Easy Street N" only has one letter at the end of the line, and is therefore not a match for your pattern.
NB: Your pattern could be simplified to:
You need to consider the data you are trying to match, and come up with a pattern to match it. Given your example, you could try:
which would match "Street" in both "123 Easy Street" and "123 Easy Street N".
"These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer
I'm trying to skip over the single character direction indicator and match "Street" whether the single character is there or not,
So match the following so it returns 'Main' in the match for any of the following
1. 123 Main
2. 123 Main View
3. 123 Main N
4. 123 Main View S
First clause matches the street.
Second clause optionally matches a single last character.
Why the extra parens in the second clause? Because I prefer to always have a match for optionals. So in this case first match is street name and second match (always there) is either something like 'S' or it is empty/null. If the parens were not there then there might or might not be a second match (you would need to test for it.)
since more than two decades programming with VC++ I never used Regular Expressions.
But now I need... The solution in VS2022 contains some thousands line looking like:
What I need is removing the ampersand (&) from these code expressions.
I found a way to search for such an expression. It is something like something like
But I could not find a working expression for Replace.
Visual Studio's "Replace in Files" option (Ctl-Shift-H) allows you to use regular expressions, for both the find and the replace parts, and even offers a drop down of selections for the more common situations.
Thank you Richard.
I know about these options in Visual Studio.
What I don't know is how to remove an & from a code line that I already found (using regular expressions) but leave all the other texts before and after this & unchanged!
I need to write a regular expression search which will locate when a line ends with the same text as the preceding line, but does not have the same first 10 characters. So in this example:
[11:12:21] Hello this is Tom. How are you?
[11:14:08] Hello this is Tom. How are you?
. . . I would need to search for consecutive lines for which the text was the same after the time entered in brackets.
I know that this search:
. . . will locate the first 11 characters and remove them.
. . . will locate lines where the first 10 characters are the same and remove them.
But I can't figure out how to structure the search so it checks the text from position 11 to the end of the line, and then checks if the text on the next line from the 11th character to the end of the line is the same.
You cannot do what you are asking with a regular expression.
(There is in fact a very wrong way to attempt this which is ridiculous and would lead to nothing but a maintenance nightmare.)
However in a programming language that uses regexes the algorithm that you would create would look like the following
1. Read a line
2. Parse the line to remove the timestamp.
3. Does it match the previous one? (Do whatever you want)
4. Otherwise save it for the next time
5. Go back to step 1 until there are no more lines to read.
My campaigns all follow the same naming convention, i am trying to use a Regex_Extract formula in DataStudio to create a new custom dimension that only displays the 4th last element in the below campaign: "ctatext"
