Create SVG Object tag with Cached SVG code

Question

I'm trying to use HTML5 localstorage for SVGs.

My existing code works on manipulation of SVG objects, which has "data" attribute, to point to the SVG file url.

Now, for HTML5 localstorage, I'm able to cache the file contents of the SVG. But I'm not able to put those contents in object tag.

If I append that cached SVG code to DIV, it looks fine, but my app don't do any manupulation of the content properly.

Is there any way, so that I could create a SVG object without the "data" attribute, and put that cached SVG contents inside that?

Or any way to build Object tag with Custom SVG data, wihout the URL depedency to it?
