DOMDocument
object. The DOMDocument
object is an extension of the DHTML DOM object. They share many methods, properties, and events, but the DOMDocument
object is much richer in object members. It has 35 properties, 25 methods, and 3 events. We covered the DOM in Columns 40 through 47. We showed you there how a loaded document is modeled by a graph, with nodes and arcs. Understanding the graph representation of a document is crucial for understanding the DOMDocument
's many properties, methods, and events. Be sure to revisit Columns 40 through 47, to get a good basic understanding of the DOM and its graph view.
