2012年1月19日 · I'm looking how to replace/encode text using RegEx based on RegEx settings/params below: RegEx.IgnoreCase = True RegEx.Global = True RegEx.Pattern = "[^a-z\d\s.]+" I have seen some examples on RegEx, but confused as to how to apply it the same way in SQL Server. Any suggestions would be helpful. Thank you.

Simple regex question. I have a string on the following format: this is a [sample] string with [some] special words. [another one] What is the regular expression to extract the words within the s...

General thoughts about replacing only part of a match. In order to replace a part of a match, you need to either 1) use capturing groups in the regex pattern and backreferences to the kept group values in the replacement pattern, or 2) lookarounds, or 3) a …

It's super easy to install (unlike the other tools): pip3 install regex-rename Do the renaming with: regex-rename "(\d{1})x(\d{2})" "S0\1E\2.srt" --rename Try "dry-run" mode (without --rename flag) in first place to check if it looks good before the actual renaming.

But maybe it isn't. Besides Apache commons has a lot more to offer. Even tough it's good to know regex, you have to be carefull on when to use it. Regex can be really hard to read, write and debug. Given some context using this could be the better solution. –
