Yes.  If you have a reference to an SVGPathElement you can call the
method getPathSegList which will return you an SVGPathSegList object.
See http://www.w3.org/TR/SVG11/paths.html#InterfaceSVGPathSegList .

You could use document.getElementsByTagNameNS(svgns, "path") which will
return a NodeList object of all the path elements in the document, in
document order.
