# XPath Patterns for Odoo View Inheritance

## Common XPath Positions

- `before` - Insert before the target element
- `after` - Insert after the target element
- `inside` - Insert inside the target element (as last child)
- `replace` - Replace the target element entirely
- `attributes` - Add/modify attributes of the target element

## Examples

### Add Field After Another Field
```xml
<xpath expr="//field[@name='partner_id']" position="after">
    <field name="new_field"/>
</xpath>
```

### Add Field Inside Group
```xml
<xpath expr="//group[@name='group_name']" position="inside">
    <field name="new_field"/>
</xpath>
```

### Replace Field
```xml
<xpath expr="//field[@name='old_field']" position="replace">
    <field name="new_field"/>
</xpath>
```

### Add Attributes
```xml
<xpath expr="//field[@name='field_name']" position="attributes">
    <attribute name="readonly">1</attribute>
    <attribute name="required">1</attribute>
</xpath>
```
