Problems solved by technology

[0006] However, since an ID assigned when registering a document called a structure guide is required, it cannot be processed in advance for a resource that is not registered outside the structured document device or for a structured document temporarily generated inside X Query. Deciding Structure Wizard
In this case, it is impossible to generate an execution plan (plan) that converts the ancestor structure conditions, sibling structure conditions, and sequence structure conditions, so there is a problem that the efficiency of the structure comparison process deteriorates.
In addition, there is a problem that the configuration becomes complicated because X Query needs to be converted into an original format using a structure guide.
[0007] In addition, when rewriting the structural conditions, it is necessary to rewrite all the structural conditions described before the target structural conditions, so there is a problem that the cost of rewriting (overhead) is large.
In addition, assuming that one structured document is the target, when applying the rewritten X Query to the structured document collection, the filtering (接り込み) conditions for the structured document collection may not be utilized and the performance may deteriorate.
Or you need to apply XQuery to each document, so the performance is worse

[0031] First, refer to Figure 1 to Figure 12 The first embodiment will be described. figure 1 It is a schematic diagram showing a system configuration example of the structured document management system according to the first 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.

[0032] 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 Processing Unit: Central Processing Unit) 101, a ROM (Read Only Memory: Read On...

[0087] Next, a second embodiment will be described. This embodiment is an example in which, when rewriting structural conditions other than descendant structural conditions, elements are not rewritten individually but are rewritten in combination with preceding and subsequent structural conditions. In addition, in the following description, the same code|symbol is attached|subjected to the structure common to the above-mentioned 1st Embodiment, and redundant description is abbreviate|omitted.

[0088] Figure 13 It is an explanatory diagram showing an example of query data assumed in this embodiment. Should Figure 13 The query data Q2 shown is described in X Query similarly to the query data Q1 described in the first embodiment. Figure 13 The query is an intent of "list the titles of structured documents described under the element whose author name is 'editor'", and includes conditions (structural conditions) related to complex hierarchical structures as described below....

Abstract

The structured document management device (1) includes: a retrieval interface unit (26), for accepting input of query data for retrieving a structured document with a hierarchical logical structure; a structural condition division unit (27), for dividing the query data into It is an element unit including a plurality of structural conditions; the structural condition rewriting unit (28), when the type of the above-mentioned structural condition to be divided is other than the descendant structural condition of the lower-level hierarchy specified by the upper-level hierarchy of the structured document, the above-mentioned structural condition The rewriting is a rewriting query including descendant structural conditions and combined operation processing predetermined for each type of the respective structural conditions so as not to affect the above-mentioned elements before and after the structural conditions; and the query execution unit (29) to The above structural conditions and the query data including the rewritten query are used as input, and the retrieval result is output.

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 methods for extracting, summarizing, and analyzing qualified data sets. 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 specified as...
