Automatically Populate Things Into The Respective Fields - Read The First Line In The Textbox And Load It Into Contact Person Field

1)i need to create a form with few fields like phoneno,website,address etc and one text area.
2) i copy n paste the details in the textarea n when i click d button. it should automatically populate things into the respective fields.

here s my logic wt i taught of:

1)read the first line in the textbox and load it into contact person field.
2)find the @ symbol and put it into the respective field and if there are more than 1 mail id load it into the same feild using commas.
3)if the phone no is 10 digits then load it into the mobile field else load the rest it into phone field.
4)find for words like road,street,block,stage,floor etc,if present then load it into the address field till the last comma is encountered.
5)the last digits in the address should be loaded into the pincode field.
6)the last word present in the address after the last comma and before the hyphen should be loaded into the city field.
7)find for www or http and load it into the website field,if not found leave it blank.
