+Preview XML attachments as a collapsible tree instead of a wall of text.
+
+Odoo stores XML attachments with the ``text/plain`` mimetype for any
+user without write access on views, so the standard file viewer renders
+them as raw text. Machine-generated XML (electronic invoices such as
+CFDI or UBL, bank statements, EDI messages) usually comes in a single
+line, which makes that preview unreadable.
+
+This module renders XML attachments with their hierarchy: indented
+nodes, highlighted tags, attributes and values, and every branch can be
+collapsed or expanded. Everything happens in the browser, no conversion
+service and no extra software on the server.
+
+**Table of contents**

+
+Usage
+=====
+
+1. Attach an XML file to any record with a chatter, or send it in a
+   message.
+2. Click on the attachment thumbnail.
+3. The file opens in the standard Odoo file viewer as a tree. Click a
+   node to collapse or expand it.
+
+Files that are not well-formed XML (or bigger than 5 MB) fall back to
+the raw text preview.
+
