When a record is created through xml data, its HTML fields should receive a `type="html"` attribute, not a `type="xml"` attribute. When important XML data with XML type instead of HTML type will have 2 differences: - The field value will be prefixed by `<?xml version="1.0"/>` - If the HTML contains multiple root nodes, the value will be wrapped in a `<data/>` tag. See `_fix_multiple_roots()` and the `xml_import` class for more details. closes odoo/odoo#98239 Related: odoo/enterprise#30491 Signed-off-by: Xavier Morel (xmo) <xmo@odoo.com>
