IE support for importing DOMNode

Question

I look on the Internet, and I'm sure I already know the answer ("no"), but I would like to check:

Does IE support importNode ()? Is there a better alternative than walking through the DOM and creating nodes? (I saw Anthony Holden's classic article , but its more than a year ago, and I hope that either IE has evolved or someone else has a different desktop)

Thanks.

I have not heard how this has changed, and in a recent post by John Resig he states:

Internet Explorer does not support importNode or acceptNode

if (!document.ELEMENT_NODE) {
  document.ELEMENT_NODE = 1;
  document.ATTRIBUTE_NODE = 2;

      var newNode = document.createElement(node »

For a lighter weight solution (assuming you don't mind adding dependencies) you can always use jQuery:

$(dom_to_import_into).find('element-to-import-into').append($(dom_to_import).clone());

This will add dom_to_importto the end 'element-to-import-into'.
