i have tried many , but some times one character failing, i am new to regex

[A-HJ-NPR-Za-hj-npr-z0-9]$

My requirements are:

• Takes all alphabet and number
• Need to exclude Q, O and I small and capital

Answer 1

You can try this:

/[^\Wqoi]*/i

• [^\W] is same as \w - will take all alphanumeric characters..
• So, [^\Woi] is same as \w - [oi]
• /i flag is for case-insensitivity.

Since you don't want to match underscores, the correct regex would be:

/[^\Wqoi_]+/i

Since, \w also include _.

Answer 2

This should work:

/\b(?:(?![qoi_])\w)+\b/i
