I want regex with at least 2 characters start with any alphabet or any digit not matters.But It can accept - and _ .
Ex : ABD , Abc_123 , 12, A-_ , A1 etc.
(Updated)
(?=[-\w]{2}).*

This should do the trick:
[\w-]{2,}
But, if you want to ignore words that have special characters, you can use this:
(?<=\s|^)([\w-]{2,})(?=\s+|$)

For example, I would like to find ty in:
erytypotym5ty
etytyty
koetymitywty
or il in:
keililmil
ilwrilltyil5ile
^.*(\w{2}).*\1.*\1.*$.
The two letters (also digits and _; you could replace \w with [a-zA-Z], if you don't want them) will be in group 1.

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}(?=[ -])

My String is -> {{mike}} {{michael}} {{jordan}}
Give me result like this
group 1 -> mike
group 2 -> michael
group 3 -> jordan
In general you can go for this
\{\{(\w+)\}\}
It captures all the characters inside the double braces (without spaces, if you need space you can use [\w\s]* inside the braces)

How to mark xy if the next symbol is not y?
I have four strings:
1. zxyy
2. zxyz
3. zxy
4. xy
The epxression should mark strings 2-4.
This regex marks the 2-nd string only:
([x][y])(?=[^y])
Thanx.
The regex recommended by Aaron works as I wished:
xy(?!y)
It marks 2. zxyz 3. zxy 4. xy, but not 1. zxyy.

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)\>\;
