I have a piece of text that I need to match anything between <latex and </latex> but not the text and an equivalent quantity of
Which given has the same divisor of <latex>5</latex> and an equivalent quantity of <latex>(5 + 2) \div 5</latex>?
I've tried with the regex \<\;(latex).+(latex)\>\;([^\s]) but it doesn't stop until the last </latex>in the line.
You need to use a non-greedy match
\<\;(latex).+?(latex)\>\;

I have strings that are concatenations of airline codes/flightnumbers, separated with ;. The airline code and flight number are either separated by a space or -. So some examples are:
AA-1234;UA 243;EK 23;
9W 23;B6-134
Now I want to grab the airline codes from this.
I came up with the following regex: [a-zA-Z0-9]{2}[ -]. This works to grab the airline codes but also includes the airlinecode-flightnumber separator. How would I adjust my regex to not include this?
[a-zA-Z0-9]{2}(?=[ -])

I'm trying to match a pattern in powershell, any 3 letters followed by any 2 numbers, example: abc00
Trying:
'abc00' -match '[a-zA-Z]{3}[0-9]{2}'
returns TRUE
but :
'abcdefg0000' -match '[a-zA-Z]{3}[_0-9]{2}'
also returns TRUE.
How do I limit it so if the string doesn't contain exactly 3 letters and 3 numbers, it returns false?
Thank you!
