1. A method for displaying network media information, the method comprising: acquiring, by a display apparatus, network media information data from a display server, wherein the network media information data comprises a model type corresponding to a network media information template, template data, and element content, and the template data comprises an element identification and model data, the element identification is an identification of an element of the network media information, and the model data is data used for describing a position relationship between a network media information element and other data for presenting a model; creating a basic element corresponding to the model type; parsing the template data to obtain the element identification and the model data; extracting, from the created basic element, a basic element matching with the parsed element identification, taking the extracted basic element as a structural element, and adding the element content to the structural element; assembling the structural element into network media information according to the model data, and outputting and displaying the network media information; wherein the template data further comprises an extension element identification and a corresponding creation expression; searching in the parsed element identification of the extension element identification for an element identification that cannot match with the basic element; and creating a corresponding extension element according to a creation expression corresponding to the extension element identification searched out, and adding the corresponding element content in the network media information data to the corresponding extension element; and assembling the structural element into the network media information comprises assembling the structural element and the extension element into the network media information according to the model data.
