javascript - Creating an SVG DOM element from a String

Question

How would I go about creating an SVG DOM element from a String?

Example:

var svgStr = '<svg width="500" height="400" xmlns="http://www.w3.org/2000/svg"><!-- Created with Method Draw - http://github.com/duopixel/Method-Draw/ --><g><title>background</title><rect fill="#fff" id="canvas_background" height="402" width="502" y="-1" x="-1"/><g display="none" overflow="visible" y="0" x="0" height="100%" width="100%" id="canvasGrid"><rect fill="url(#gridpattern)" stroke-width="0" y="0" x="0" height="100%" width="100%"/></g></g><g><title>Layer 1</title><path id="svg_1" d="m118,242l64,-153l63,157c0,0 45,-71 49,-68c4,3 11,146 12,146c1,0 -173,-7 -173,-7c0,0 -61,-72 -61,-72c0,0 110,-156 46,-3z" fill-opacity="0.7" stroke-width="2" stroke="#995757" fill="#995757"/></g></svg>';

You can use DOMParser to parse an XML string.

var parser = new DOMParser();
var doc = parser.parseFromString(stringContainingXMLSource, "image/svg+xml");

The root element for the parsed string will be doc.documentElement

For this to work properly cross-browser you'll need to set the html namespace i.e. your string will need to look like this...

var svg2='<svg xmlns="http://www.w3.org/2000/svg" width="500" height="500" ...
