DOM Domain
This domain exposes DOM read/write operations. Each DOM Node is represented with its mirror object
that has an id. This id can be used to get additional information on the Node, resolve it into
the JavaScript object wrapper, etc. It is important that client receives DOM events only for the
nodes that are known to the client. Backend keeps track of the nodes that were sent to the client
and never sends the same node twice. It is client's responsibility to collect information about
the nodes that were sent to the client. Note that iframe owner elements will return
corresponding document elements as their child nodes.

Methods
DOM.describeNode #
Describes node given its id, does not require domain to be enabled. Does not start tracking any objects, can be used for automation.
Parameters
nodeIdOptional
Identifier of the node.
backendNodeIdOptional
Identifier of the backend node.
objectIdOptional
JavaScript object id of the node wrapper.
depthOptional
integerThe maximum depth at which children should be retrieved, defaults to 1. Use -1 for the entire subtree or provide an integer larger than 0.
pierceOptional
booleanWhether or not iframes and shadow roots should be traversed when returning the subtree (default is false).
Return object
node Node description.
DOM.enable #
