Hi guys,

I am struggling with regular expression.Can you please suggest the regular expression for the below patterns.
I have tried many times with several patterns but still i could not resolve the below patterns.

  1. Must contain at least one alpha character (i.e. a, b, c etc,)
  2. Only accept the characters: numerals, spaces, +

    Also,provide some valuable reference urls.

    Thank you,
    Prem

Does it have to start with a letter, or can it be anywhere in the string? Can you provide some samples?

This can be a start:

[a-z \+]+

If it always starts with a letter:

[a-z][a-z \+]*

No conditions. It can starts with letter or number or end with letter or number.
But only thing is it should contain one alphabet mandatory.

First name must conatain atleast single alphabet character.

Give examples of the possibilities. Not a description.
