Access text field value in block

I am new in magento extension development .

How i access street value in edit.phtml of 'id=street_1' textfeild in Edit block .

Please give me suggestion in detail.



You can access it in _prepareLayout from the Edit.php block like this.

$value = $this->_address->getStreet(1);

EDIT-based on comments

You can access the address before saving it in Mage_Customer_AddressController::formPostAction with

$street = $this->getRequest()->getPost('street'); 
$part1 = $street[0];

To access/modify/validate the address before saving it use the event customer_address_save_before.
