Abstract
XML(eXtensible Markup Language) is used as the description form of the documents and the data exchanged on the Web. Now, the usage of the XML is extending to not only the exchange of the XML document but also that of the XML database for classification and retrieval. This paper develops how to retrieve the related objective data from the tree structure in the XML document for the classification. In this paper, an ordered preserving relation is defined as the cue of the retrieval of the objective pattern. Then, the problem is to find the ordered preserving relations in the document. In the document, the ordered and the unordered subtree structure are important in the retrieval and classification. Then, the retrieval value is calculated in the tree structure. A method developed here was applied to the practical XML document.
