XPath data type XPath can be divided into four types of data: Node Set (node-set) A node set is a set of nodes that match the criteria returned by a path.

First, the preface has always been to the tree-related things to be deterred. Before every time said to see, because of inertia, time is so wasted. Make a decision today, decide to be gooddata structure in the things to look at. Do not know to see this article you, is not and I have the same feeling, empty a hard heart, but slow to pay action. If so, if also want to take good knowledge of the tree to consolidate, let us together chew knowledge point over it. This article strives to let every stu

This chapter mainly describes: 1.Floyd-warshall algorithm : To solve the shortest distance between any two points, the time complexity of O (n^3). (1) The use of conditions scope: Usually can be used in any diagram, including a direction graph, with negative right side of the graph. (2) Freud (Floyd) algorithm process:1, with D[V][W] record the shortest distance of each pair of vertices.2, scan each point in turn, and then iterate through all the values of each pair of vertex d[][] to see if th
