Unwanted namespaces on SVG markup when using XMLSerializer in JavaScript with IE
OK, I think I've solved it. Followed the trail from this post to this WebKit bug report and this test case.
If I change the script to this, then it works:
var el = document.createElementNS('http://www.w3.org/2000/svg', 'svg');el.setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns', 'http://www.w3.org/2000/svg');el.setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:xlink', 'http://www.w3.org/1999/xlink');var markup = (new XMLSerializer()).serializeToString(el);console.log(markup);Ah namespaces.
But, it fails in an older version of WebKit that is still present in Safari 6.05 and PhantomJS (bug report - now fixed). Presumably the fix is incorporated into the latest Safari update (I haven't yet checked).
