Can't do an xpath in openerp 7 - xpath

Question

Hello I'm usually coding in Odoo v10 and +,
Now I have to code on OpenERP 7, and I don't succeed to do a simple Xpath !
Here is my XML stock_view.xml
<?xml version="1.0" encoding="UTF-8"?>
<openerp>
<data>
<!--...-->
<!--...-->
<record model="ir.ui.view" id="view_picking_in_form_adquat">
<field name="name">stock.picking.in.adquat</field>
<field name="model">stock.picking.in</field>
<field name="inherit_id" ref="stock.view_picking_in_form"/>
<field name="arch" type="xml">
<xpath expr="/field[#name='origin']" > <!--position="after"--> <!--...-->
<string>I'm Here</string>
</xpath>
</field>
</record>
<!--... -->
</data>
</openerp>
It seems the error is in the arch field : "ValidateError Error occurred while validating the field(s) arch: Invalid XML for View Architecture"

Can someone tell me if there is syntax differences between odoo and openerp ?

Answer 1

try this it may help you i think that you just need to add another slash
<xpath expr="//field[#name='original_field']" position="after">
<field name="new_field"/>
</xpath>

Answer 2

There is no section for new in Odoo 8 as described in Odoo 8 views.
XPath should be the same.
a field element with a name attribute matches the first field with the same name
You can add an element to the view using field:
<field name='origin' position="after">
<string>I'm Here</string>
</field>
Or just add another slash at the beginning of your XPath expression as mentioned by #imad.
