Embodiment Construction

[0031] Hereinafter, a structured document management device, method, and program according to an embodiment will be described with reference to the drawings.

[0032] figure 1 It is a schematic diagram showing a system configuration example of the structured document management system according to the embodiment. Here, as a structured document management system of an embodiment, it is assumed that figure 1 As shown, a plurality of client computers (hereinafter referred to as client terminals) are connected to a server computer (hereinafter referred to as a server.) 1 which is a structured document management device through a network 2 such as a LAN (Local Area Network). 3 server client systems.

[0033] figure 2 It is a block configuration diagram of the server 1 and the client terminal 3 . The server 1 and the client terminal 3 have, for example, a hardware configuration using a normal computer. That is, the server 1 and the client terminal 3 include: a CPU (Central Pro...

Abstract

The structured document management device according to the embodiment analyzes the hierarchical conditions included in the input query and the predicate conditions corresponding to the elements of the structured document specified by the hierarchical conditions, and extracts the constraints and variables among the variables storing each element. dependencies between. When the constraints are extracted by this method, the constraints related to the structure are acquired in a form that includes not only the original target elements but also elements other than the target elements. After moving the predicate so that the relaxed constraint condition can be applied as early as possible, a predicate condition that complements the relaxed condition is inserted.

Description

technical field [0001] Embodiments of the present invention relate to a structured document management device, method, and program. Background technique [0002] Conventionally, a structured document management device for storing and retrieving structured document data described in XML (Extensible Markup Language: Extensible Markup Language) or the like is known. In order to retrieve structured document data in a structured document management device, a query language X Query ( XMLQuery Language), and is supported in most structured document management installations. [0003] X Query is a language for processing XML data sets like a database, and provides means for extracting, summarizing, and analyzing data sets that meet conditions. Since XML data has a hierarchical logical structure (hierarchical structure) in which elements such as parent and child are combined (hierarchical structure), conditions related to the hierarchical structure (structural conditions) can be spe...
