DOM Remove Nodes

This lesson is part of XML · All levels

Summary

The node is removed from the tree by removing its parent's child, or by the remove() method on the node itself on the modern DOM. The deleted result nodes can still be stored in a variable for reuse, but no longer appear in the document. Removing the element also removes the entire subtree underneath it.

Key points

RemoveChild is called to the parent and returns the deleted node
It makes it easier to remove on modern DOMs.
Subtree and offspring are removed from the tree
The resulting deleted node can still be saved for reuse.
Deletion updates the document's appearance directly
