    <?xml version="1.0"?>
<xpath expr="/form/sheet/notebook/page/field[@name='order_line']/form/group/group/field[@name='product_id'] | /form/sheet/notebook/page/field[@name='order_line']/tree/field[@name='name']" position="before">
              <field name="barcode_id"/>
              <field name="publisher"/>
          </xpath>

Answer 1

你可以试试这种 XPath ：

/form/sheet/notebook/page/field[@name='order_line']//field[@name ='product_id' or @name='name']

Answer 2

Wiest,

AFAIK In odoo, it's forbidden functionality that doesn't consider multiple XPath correspondence.

In the alternative, you could override fields_view_get and use XPath through lxml library.
