- The namespace code representing the (prefix, uri) pair of the namespace binding to be
added. If the target element already has a namespace binding with this (prefix, uri) pair, the call has
no effect. If the target element currently has a namespace binding with this prefix and a different URI, an
exception is raised.inherit
- If true, the new namespace binding will be inherited by any children of the target element
that do not already have a namespace binding for the specified prefix, recursively.
If false, the new namespace binding will not be inherited.public void replace(NodeInfo[] replacement, boolean inherit)

This method takes no action unless the target node is a document node or element node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.
The supplied nodes will be copied to form the new children. Adjacent text nodes will be merged, and zero-length text nodes removed.

This method takes no action unless the target node is an element, text node, comment, or processing instruction, and one that has a parent node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.
The supplied nodes must use the same data model implementation as the tree into which they will be inserted.
