Various embodiments are disclosed relating to binding an application to one or more nodes of a tree (e.g., XML tree or XML document). According to an example embodiment, a tree path navigator (e.g., XPath navigator) may be invoked or called to dynamically evaluate a tree path expression to track one or more nodes identified by the expression. In another example embodiment, a notification interface may be provided for one or more nodes in the tree to provide a change notification when one of the nodes is modified. The application may be notified of a change to any node identified by the tree path expression.
