Chilkat XML offers a high-performance alternative to the standard XML DOM for creating, navigating, and manipulating XML documents. The Chilkat XML parser is faster and less memory intensive, and the API is much simpler. There is only one interface, which represents a single node in a parsed XML document. A node can contains a tag, attributes, content, and 0 or more child nodes.
