Visualizing total order relation of nodes in a structured document
prior request for http://www.google.com/patents/US20120137209
A method, system, and a computer readable storage medium for visualizing total order relation of nodes included in structured document, the method includes the steps of:
acquiring log information, where the log information is created by storing information on transitions between nodes in a structured document in chronological order;
specifying a relation of relative positions of the nodes in the transitions based on acquired log information; and
determining a total order relation of the nodes in the structured document by performing a topological sorting that uses specified relation as a constraint, where the total order relation of the nodes is determined by using content data of said node if the node is added to or removed from the structured document; and where at least one of the steps is carried out using a computer device.
