Run the mutation method macro. Pre-insert node into the context object's parent before the context object. The after(nodes) method must run these steps: If the context object does not have a parent, terminate these steps. Run the mutation method macro. Pre-insert node into the context object's parent before the context object's next sibling. The replaceWith(nodes) method must run these steps: If the context object does not have a parent, terminate these steps. Run the mutation method macro. Replace the context object with node within the context object's parent. ]] These steps only refer to a single node, not the collection of nodes and/or DOMString values that can be passed to each method. 118045 1 annevk 2015-02-20 06:54:28 +0000 Josh, the mutation method macro takes care of that, no? Having said that, these methods need some fixes to their algorithms. In particular when passed the context object. 118046 2 josh 2015-02-20 08:40:01 +0000 Oh, my mistake; I skimmed over step 2 every time while reading it. 120231 3 annevk 2015-05-08 09:13:24 +0000 See https://github.com/whatwg/dom/issues/32 for some work that is needed here.
