merging two doms

[vissuyk]

Hi,

What API exists to merge two in-memory dom trees? I saw importNode but
not sure if it handles the merge in all cases (e.g new child elements,
deleted child elements re-parenting etc).

Is importNode the right API ?. Is there any other api or code that
anyone can share ?.

Thanks a lot

I believe DOM nodes can only be placed into the tree that owns them. If
I remember correctly, you'll need to use importNode to deep-copy a DOM
sub-tree into another tree if you want to merge.
