Hi Aashish
Once you've describe an object in defs section, here Gr, it is
considered as one single element.
So, when you use it by <use> element, you can't access to any child of
this object.
On the other hand, in your example, if you change some attribute of the
rect of "Gr", it will impact any reference to "gr", ie u1 AND u2,
because you've changed the symbol itself.
You cannot apply modifications only to U1, and not to U2.
But:
if you have something like
<defs>
<rect id="myrect" x="10" y="10" width="50" height="60"/>
</defs>
<use xlink:href="#myrect" id="U1">
<use xlink:href="#myrect" id="U2">
, you can define differents color for the two <use>. To do that , change
the <use> attributes directly :
doculent.getElementById('U1').setAttribute('fill','blue'), and not the
definition of the referenced object.
That way, you can have different representation of a single referenced
element. But you cannot change its définition.
Hope it helps
