SVGOMUseElement.getInstanceRoot() ?
Hi,
the SVGOMUseElement.getInstanceRoot() returns
" !!! TODO: getInstanceRoot()"
Is there any development under way to implement
getInstanceRoot() to support scripting of
the <use> tag?
thanks,
Marcel

Correct, the elements would not implement the ElementInstance
interface, and changing the element referenced by the ElementInstance
(if you were to just create them on the fly) wouldn't update all
use instances.

Is the reason that the initial implementation is wrong is that the use'd
elements are actually cloned and not just referenced, so that a simple
getInstanceRoot function returning the element from the
SVGOMCSSImportedElementRoot wouldn't be correct?
Thanks,

Thanks for the response,
i'm currently too busy to start implementing this,
removing my <use> links will solve it for the time being.
thanks,

Hi Mercel,
There is currently no development under way to implement this.
The initial implementation of use was wrong with regards to the
spec and fixing this is non-trivial (and the need is usually not obvious). I
have given thought to how it may be implemented properly but don't
expect it to be fixed by the Batik committers soon. Contributions
are always welcome.
