In order to apply the technique of data cache to extensible markup language (XML) database system, the XML-cache system to support data cache for XQuery is presented. According to the character of XML, the queries with nesting are normalized to facilitate the following operation. Based on the idea of incomplete tree, using the document type definition (DTD) schema tree and conditions from normalized XQuery, the results of previous queries are maintained to answer new queries, at the same time, the remainder queries are sent to XML database at the back. The results of experiment show all applications supported by XML database can use this technique to cache data for future use.
