  • Regexp for html forms

    Is there a regexp to parse out all inputs from an html form? Ideally it
    will give out the input field names and their values. If nothing ready
    is available, would regexp be a good choice here?


    <form action="/process.php">
    <label for="fname">First name:</label><br>
    <input type="text" id="fname" name="fname" value="John"><br>
    <label for="lname">Last name:</label><br>
    <input type="text" id="lname" name="lname" value="Doe"><br><br>
    <input type="submit" value="Submit">
    <input ...>
    </form>

    Please ignore. I found something that I can work with.

    tdom is your friend. Now also for JSON.
    It also translates all the &uuml; etc...

    Yes, best to use a proper HTML/XML parser. While one can craft a regex
    to "parse" one specific given HTML form, it is impossible to write a
    regex that will parse any given HTML form.

    Thank you both! Learned something useful about tdom in the process.
