Get attribute this way

[King]

Writing/Reading data to xml is not a problem. The problem is when I
have to write to attributes in xml, where a connections has been
established.
XML:
<Connection sourceattribute="node1.gradient.colors[0][1]"
destattribute="node2.gradient.colors[1][2]"/>

While reading back I have to convert both source and destination
strings into object so that I can call connections function using
source and target attributes.
