Select element with double dot in id, error: “#octo:cat” is not a valid selector

问题

Given an svg with an existing id="kvg:StrokeNumbers_07425",

<g id="kvg:StrokeNumbers_07425" style="font-size:8;fill:blue;">...</g>

I do the following :

d3.select("#kvg:StrokeNumbers_07425").attr("style","fill:red;");

and get the following error message :

Uncaught SyntaxError: Failed to execute 'querySelector' on 'Document': 
'#kvg:StrokeNumbers_07425' is not a valid selector.

It's likely due to the :.

What should I do to make it work?

Escape the : as such

d3.select("#kvg\\:StrokeNumbers_07425").attr("style","fill:red;");
