Odoo 14 Community Version

Hi,

I follow the link as below to edit  XML/HTML to set the default country , it works.

https://www.odoo.com/forum/help-1/odoo-12-default-country-on-checkout-form-for-ecommerce-175592

After, I try to set the default city to a value, and I screw up the xml page and have the following errors.

Error when compiling AST SyntaxError: invalid syntax (, line 1) 

Template: website_sale.address

Path: /t/t[2]/div/div/div[2]/div[2]/div/form/div[1]/div[9]/input

Node:  

Actually I tried to find the xml file on the server /opt/odoo/odoo14/addon/website/view, website_sales/view, and others.

But I cannot find the file. Actually where is it located?

Thanks
