Thanks Helder for the links. I personally don’t use SVG within IE anymore (a statement more than a technical hurdle), but I hope your comment reaches those people that do.

Recently stumbled upon two links that help implementing this idea without using the embed nor conditional comment hacks:

* http://my.opera.com/Andrew%20Gregory/blog/2007/08/04/svgs-on-web-pages
(original post where this was seen in the first place)
* http://joliclic.free.fr/html/object-tag/en/object-svg.html
(source link where above link is based on)

I’ve made a few experiments and this seems to do the trick, at least in IE+ASV, Firefox, Safari and Opera.

Hope this helps,

Sorry, i didn’t really write down what i was thinking. Maybe i’m more awake this time:

I meant

steltenpower: I’m not sure I follow the question exactly. I guess you are proposing that I write a PHP script that will create a page from a given SVG URI but wrap the given SVG URI into an object (in most cases) or an embed (in the IE+ASV case)? Kind of like a “HTML harness” for SVG. This isn’t a bad idea, good for other authors to test it out, but my script doesn’t do anything particularly fancy. My concern was more for authoring my own SVG content embedded already in HTML (via object tags) and then have some client-side script that transforms it into embed tags in the case of IE+ASV.

Maybe you can clarify what you want the PHP file for…

Where’s the http://yourserver.com/automatically_stuff_in_the_javascript.php?URL=http://myserver.com/mycontent.svg
?

I still haven't wrapped up my whole browser sniffing thing in my head. Adobe has a pretty complex example, though it's aged and would have to be updated. Anyway, as far as I can tell, there's no way to find out the actual SVG renderer being used from within a JS environment. For instance, in Fx I can use this extension to disable the native rendering and use something else (ASV) for instance. And if you're talking about logging the combination then that would have to be done at the server-side, which is another layer removed from the actual user experience/environment.

Looks great, you keep the content on the page as much as possible and only replace what you need to.
I take it this means you’ve decided to stick with passive browser sniffing? I’d throw in something to track which combination of viewer and browser is being used, but we’ll see how it goes when I finally get around to it.
