DOCUMENT PROCESSING DEVICE AND DOCUMENT PROCESSING METHOD

摘要

It is possible to appropriate process data structured by the markup language. When a DOM management unit (35) has read a gigantic document, the DOM management unit (35) temporarily generates a DOM tree and them saves a part of the information contained in the DOM tree to a storage device (17) such as a hard disc. The DOM management unit (35) may compare the memory consumption amount of the generated source tree to the current memory remaining amount, thereby judging whether to save the data into the storage device (17). Moreover, the DOM management unit (35) may select any of the information to be saved into the storage device (17) according to the DOM tree memory consumption amount, the memory remaining amount, the remaining amount of the storage device (17), the operation speed of the CPU, and the like. The DOM management unit (35) leaves the information indicating the tree structure in the memory and saves information such as the element name, the attribute name, the element value, and the attribute value into the storage device (17).
