Hi,

Yes, it's possible to use Extension Views in XML to inherit a base view and replace multiple items using XPath expressions. Your example demonstrates the use of XPath expressions within <xpath> tags to replace specific elements in the base view.

<template id="inherit_base_view" inherit_id="base.view">
    <xpath expr="//p[@id='powered']" position="replace"></xpath>
<xpath expr="//div[contains(@class, 'by_odoo')]/a[contains(@href,'https://www.odoo.com" rel="noopener nofollow noreferrer" target="_blank" data-saferedirecturl="https://www.odoo.com')]"" rel="ugc">https://www.google.com/url?q=https://www.odoo.com&source=gmail&ust=1715316861287000&usg=AOvVaw29BwovjeEHdvxU8dv10yVk">https://www.odoo.com')]" position="replace"></xpath>
</template>
<!-- Extra content -->

Make sure that your XML document only contains the necessary content within the expected structure. In this case, it seems like the extra content is placed after the closing tag of the template, which is not allowed.

Hope it helps
