Abstract
Under the present invention, a set of filters (e.g., one or more) is associated with a hierarchical tree, which includes sets of namespace nodes, element nodes and variable nodes. Once the set of filters is associated with the hierarchical tree, a network document is parsed and compared to the hierarchical tree to identify a set of corresponding filters. Each corresponding filter is then evaluated based on the network document to determine which, if any, are “satisfied.” The network document is then communicated to the user(s) that correspond to the satisfied filter(s).
