Hi, 

As per the etree code you can import the etree and finding of the xml arch, in those cases it will be using full.

import xml.etree.ElementTree as xee
from lxml import etree

view_id = self.env.ref('model.model_view_name')
view_arch = str(view_id.arch_base)
doc = xee.fromstring(view_arch)
field_list = []
field_list_1 = []
for tag in doc.findall('.//field'):
    field_list.append(tag.attrib['name'])
 
    if 'attrs' in tag.attrib or not 'invisible' in tag.attrib['attrs']:
        field_list_1.append(tag.attrib['name'])
 
    //You can add your own conditions here 
 

model_id = self.env['ir.model'].sudo().search(
    [('model', '=', 'model_name')])
return [('model_id', '=', model_id.id), ('state', '=', 'base'),
        ('name', 'in', field_list)]

Regards
