Replace html tag (or body tag) attributes

[davidjr82]

I have a specific case where I need to replace the whole document without making a redirect.
This replacement is set from the server side.

To do so, I use the "HX-Retarget": "body" and "HX-Reswap": "innerHTML" headers in the response.

As the head (styles, etc.) is also changed, I use the head-support extension.

With these two things I am almost there. The only part of the document I can't change is the html tag itself or the body tag itself. This html tag has a data-theme attribute that enables some styling. The new page shouldn't have this styles, so it hasn't this html attribute.

Is there any way to replace/remove the html tag attributes with the new ones sent by the response?

Thanks!
