<p>how to use Regular Expression for address field validation,  where i need to only alphabets, numbers and certain symbols(not all symbols). how should i write the regular expression for the same. can anyone guide on this? </p>

<p>in marks list, i want to validate the text box,that it shud contain only numbers(no alphabets, or other symbols except "dot" ".") (b'coz the number can be a decimal also). so i would like to write a regular expression that will match only --- number and ".", other alphabets and symbols it should disagree.</p>

<p>also in address field, required symbols are ("/", ".", "-", "#", numbers, alphabets) other symbols not allowed. How should i write a regular expression for the same.</p>

<p>Can anyone guide me on this?</p>
