Working with regular expressions on fieldsets in JavaScript jQuery

I'm facing an issue with a JavaScript regexp and I could really use some assistance.

Currently, I have an ajax query result saved in a variable (in this case, a regexp) and I am trying to only match the content within the fieldset tag.

Here is a snippet of my HTML code:

<fieldset class="form-wrapper" >
    <form action="/users/login" id="UserLoginForm" method="post" accept-charset="utf-8"><div style="display:none;">
        <input type="hidden" name="_method" value="POST" /></div>
        <div class="input text required">
            <label for="UserUsername">Username</label>
            <input name="data[User][username]" type="text" maxlength="255" id="UserUsername" />
        </div>
        <div class="input password">
            <label for="UserPassword">Password</label>
            <input type="password" name="data[User][password]" id="UserPassword" />
        </div>  
        <div class="submit">
            <input type="submit" value="Login" />
        </div>
    </form>
    <p id="user-management-links">
        <a href="/users/forgotten_password">Forgotten password ?</a>        
        &nbsp;|&nbsp;<a href="/users/register">Sign up</a>  
    </p>
</fieldset>

And here are my regular expressions :

This one is working fine:

var regexp = content.match(/<form .*?>(.*?)<\/form>/)[0];

However, this one is not working:

var regexed = content.match(/<fieldset>(.*)<\/fieldset>/)[0];

Thank you in advance for any help you can provide!

Answer №1

In order for your regex to work correctly, make sure to include the .*? in the first section. It seems like you might have forgotten to include it initially. 

Additionally, it is worth noting that enabling the dot to match spaces and new lines in JavaScript may affect the functionality of your regex. As a solution, you can try the following regex pattern:

    <fieldset .*? >(.|\W)*</fieldset>

This pattern should work without the need to enable any special options in JavaScript.

It's always important to double check your regex patterns for any missing components, and consider the impact of additional options on the overall functionality.
