I am learning regex. I want to match something like this - 2 letters, 2 numbers, 4 letters, 10 numbers All these need to be there and in above order too. So far come with this regex

[A-Za-z]{2}[0-9]{2}[A-Za-z]{4}[0-9]{10}

But I want to do exact match. 'XS42NLJK1234567890' should match but not this one 'XS42NLJK123456789015' But its matching the 2nd string too.I want exact match. Any help highly appreciated.

Remove spaces from the character classes if you do not plan to match them. The main thing is you need anchors, `^` and `$`, around the pattern. – Wiktor Stribiżew Jun 10 '20 at 08:53
`[A-Z a-z]` means "any letter **or a space**". I don't think that's what you meant. This should just be: `[A-Za-z]`. – Tom Lord Jun 10 '20 at 08:54
