It is possible to edit the XML code in WebView pages. By default, the pages are zipped, so you will need to ensure they are saved as plain text. To do that:
Open the WebView application in Design mode.
From the menu, select .
Scroll to the section .
Check the setting for Zip files on server and if it
is True change it to False.
If you changed that setting, then for each page that you need to edit, open the page and then save it again.
You should now be able to make edits to those pages with any text or XML editor.
