Using webform rules to create node after webform submission
You should use Rules module in the following way:


Install and enable Rules module
Install and enable Webform Rules (https://drupal.org/project/webform_rules)
Create a new rule
Choose the "After a webform has been submitted" event
Optionally set your conditions
Add a new action "Create a new entity" of type "Content"
Add the neededs action to add properties to the created entity
Add the save action


I hope this helps.
