Can someone please explain the difference between Element.setAttribute and Element.setAttributeNS(), as it affects Batik? My code loads a document into the canvas and performs various modifications to the DOM, adding various <g>, <rect> and <line> Elements. I notice that through accretion, my code is using all of the following in various places:
e.setAttribute(attribName, attribValue); e.setAttributeNS(svgNS, attribName, attribValue); e.setAttributeNS(null, attribName, attribValue);
It seems that some attribs need the SVG namespace (e.g. the xml "id" attrib.) Others are happy with no namespace (<line> x/y coords.) Yet others seem to need the null namespace (the width/height of the <svg> element.) Are there some general rules about when & how to supply a namespace for attributes?
Thanks
