Gravity Form Form Name Attribute - php

Question

The Page Analytics I use gathers the form data automatically. Gravity Forms create tag without any name attribute. I am trying to figure out a way to assign form tag a name attribute.
The closest I have reached is this example:
<?php
add_filter("gform_form_tag", "form_tag", 10, 2);
function form_tag($form_tag, $form){
if ($form["id"] == 3){
$form_tag = preg_replace("|action='(.*?)'|", "action='custom_handler.php'", $form_tag);
return $form_tag;
}
}
?>
But I am not sure how to use preg_replace to create a name attribute for form in question.

I figured out a solution to suite myself. Sharing it for any other troubled soul. for me all I wanted was to add a name attribute for the forms so that my analytics picks up something understandable instead of ids like form-1234 so I browsed plugin/gravityforms/forms_display.php and edited it where it creates a new form tag. can be found between line 435 to 440. created a new variable to hold value of form title, edited it to remove spaces. and inserted it to the form tag string.
//Edited For Analytics
$cm_form_name = str_replace(" ", "-", $form['title']);
$form_string .= apply_filters("gform_form_tag_{$form_id}", apply_filters("gform_form_tag", "<form method='post' enctype='multipart/form-data' {$target} id='gform_{$form_id}' name='{$cm_form_name}' {$form_css_class} action='{$action}'>", $form), $form);
//End Editing
//Orginal String
//$form_string .= apply_filters("gform_form_tag_{$form_id}", apply_filters("gform_form_tag", "<form method='post' enctype='multipart/form-data' {$target} id='gform_{$form_id}' {$form_css_class} action='{$action}'>", $form), $form);

I wrote a plugin that also makes adding a name attribute (or modifying/adding/removing any other attribute for the form tag) a breeze.
http://gravitywiz.com/gravity-forms-tag-editor/
Here's an example for adding the name attribute:
new GW_Tag_Editor( array(
'tag' => 'form',
'name' => 'form_{formId}',
) );

I had a slightly different goal, but thanks to Jeff's idea I came up with the following approach that I think is worth sharing.
It appends a sanitized form name data attribute to the form tag, without touching any other attributes.
function add_form_name_data_attr($form_tag, $form){
$form_tag = str_replace('>', ' data-form-name="' . sanitize_title($form['title']) . '">', $form_tag);
return $form_tag;
}
add_filter('gform_form_tag', 'add_form_name_data_attr', 10, 2);
I can then use that data attribute in JavaScript to differentiate the various forms when calling a certain analytics API.
