Check if word exists twice? (Regex) [closed]
(5 answers)
Closed 4 years ago.
I want to check with regex if the word link appears twice in a sentence.
The sentence goes: "This link is invalid. Try the link below." --> here I need the regex to check if "link" appears twice.
This is my first time trying regex and I only understood the grouping so far like \b(link)\b. With this I can check if the word link even appears but I need to know if it appears twice.
How can I achieve this?
Try this one:
\b(link)\b(?=.*\b\1\b)
This gives you the first occurrence of the duplicate word.
Tested it with your sentence here: https://regex101.com/r/2zGSKj/2
A shorter solution without groups would simply be
\blink\b.*\blink\b
Tested it here: https://regex101.com/r/2zGSKj/3

How do I match an entire string with a regex?
(8 answers)
Closed 5 years ago.
I believe my validation is correct however it is not working.
My regular expression pattern is
ValidationExpression= "(I|II|III|IV)[DEF]?"
Basically, the user should put any of the first options then with optional D, E or F
Valid text Example: IIIC
Thank you
I don't know much about regex, but I did a quick bit of googling and came up with this:

It explains how it works at the side :)

I have a bunch of file names like this a1_b2_c3_d4.png but I want them to renamed like this a1_b2_d4_c3.png. I am having NameChanger application to implement regex on file names. I could not figure out regex to swap c3 and d4. If anyone can help me with the regex, that will be great.
There are three permutations to what you ask:
If you only care about the last 2 before the dot
find ([^._]+)_([^._]+)\.
replace $2_$1.
If it has to be exactly the 3 rd or 4 th before the dot
find ^([^._]+_[^._]+_)([^._]+)_([^._]+)\.
replace $1$3_$2.
If it has to be exactly the 3 rd or 4 th without dot
find ^([^._]+_[^._]+_)([^._]+)_([^._]+)
replace $1$3_$2
