Regular Expressions

You don't say what environment you are working in, so it's hard to give you useful code. However, you can probably get what you want by either doing a search & replace operation, possibly repeated, or by using some kind of "regex iterator" approach. For C++, it would be a regex iterator (iterate over all the matches of THIS pattern in THAT string). For something like Python it would be find all occurrences of THIS pattern in THAT string. In order to drop the "8;" from your example sentence, you'd want to provide a better pattern than just "some digits." Instead, use something like /(\d+):/ to match on one-or-more digits followed by a colon. You want to capture the digits, not the colon. If you can just iterate over all matches in the string, that will probably be enough. If you're doing sed or some other editor, you'll have to search and replace the line. If possible, see if you can do something like a non-greedy match (.*?) to match all the text between matches, and then replace it with a comma. (FYI: The ? operator is a non-greedy modifier in Perl-style regex engines. Other regex engines may not support this at all, or they may have a different syntax-- for example, Vim would use .\{-} for that.

Never heard of DataCleaner. Don't use it and not going to start. If it's some tool you found somewhere, your best source of support is going to be whoever wrote it. Your BIGGEST mistake was never telling anyone you were using some tool to do this work instead of writing your own code to do it.

Thanks man

So, this is my attempt I tried the following regex in Java 8, (?i)(Helló) (Wórld) which matches HeLlÓ WóRlD the replacement string \U$1 \L$2 should become HELLÓ wórld, but it doesn't work. Can someone please help me???

Adding the leading zeroes with only a Regular Expression replacement may prove difficult. If you're trying to match the two formats, it may be better to convert the other way. What are you really trying to do?

Check the raw source of the string you're trying to match. It could be that the ° character is actually °, °, or °. Or it could be a different Unicode character entirely - for example: º = º / º / º ˚ = ˚ / ˚ / ˚ ᵒ = ᵒ / ᵒ ゜ = ゜ / ゜ ᣞ = ᣞ / ᣞ ⁰ = ⁰ / ⁰ Your minimum temperature regex doesn't try to match the character, but your maximum temp regex does.

Does it have to be regex? There's StringUtils.leftPad () if you want to pad with leading 0s, as long as you know the total length you want. Or use a format string to do it. String paddedStr = String.format("%09d", originalVal); (I think) We won't sit down. We won't shut up. We won't go quietly away. YouTube, and My Mu[sic], Films and Windows Programs, etc. and FB

I am not a regex expert I am afraid. But You can go to RegExr: Learn, Build, & Test RegEx[^], and try different sets to see what may work.

Your function works fine for me if you pass in the correct values. const string input = "\"\"|*\"I have delimiter |* and an escaped \\\" quote in me\"|*100|*200|*300|*\"am a string\"|*\"\""; string[] result = Split(input, "|*", @"\""", false); Split | C# Online Compiler | .NET Fiddle[^] "These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer

Thanks Richard. I finally ended up working out the following: (?<=Cycle)\d{4} This returns the '0001' like I want. I actually came close to working this out before posting, but failed to notice that I had a space before the \d. Duh.

This doesn't look like a suitable case for regular expressions. You'd have to build a regex pattern containing every possible sequence to test for, because regex doesn't have a construct for comparing the difference between two characters within a match. It would probably be easier to implement this using a loop. Check each five-character substring from the input to see if it's contained within a string containing the letters in sequence, remembering to account for case and accents if required.

I'm not a Reg Exp expert, but I recall that '.' matches anything EXCEPT newline so try replacing (.*$) with ((.|\n)*$). You may also need to switch on multiline matching
