I have created a module that allows me to add some fields in a new page and now in the same xml file i tried to delete another existing page but it gives me the error that the View inheritance may not use attribute 'string' as a selector.

to specify what i want to delete it's the Inventory page of product.product_template_form_view
here is my code using the xpath expression

<record id="view_product_form_inherit" model="ir.ui.view">
     <field name="name">product.template.common.form.inherit</field>
     <field name="model">product.template</field>
     <field name="inherit_id" ref="product.product_template_form_view"/>
     <field name="arch" type="xml">
     	
      <data><xpath expr="//page" position="after">
      	<page name="Sample" string="Caractéristiques">
            <group>
                
                <field name="etat"/>
                <field name="famille"/>
                <field name="description"/>
                <field name="nb_pierre"/>
                <field name="carrat"/>
                <field name="datevt"/>
           </group>
        </page>
      </xpath>
	  <xpath expr="//page[@string='Inventory']" position="replace"/>
	  
	  
     </data></field>
    </record>
