Abstract

A data tree is generated in memory by parsing a first XML file. Default setting requests and validation requests are read from a second XML file. Default data values for nodes in the data tree are generated by executing default data generation code from locations specified in the default setting requests and recorded in the data tree. The content of data stored in nodes of the data tree is then validated by executing validation code from locations specified in the validation requests. The data tree is then searched by getting a nodepath, parsing the nodepath into a plurality of path pieces, searching the data tree based on each of the path pieces, and returning one or more nodes of the data tree based on the search that satisfy the path pieces. A data value of one or more nodes or child nodes may be specified to narrow the search.
