In this paper, we define “XQuery!”, an extension of XQuery 1.0 that supports first-class XML updates and user-level control over u...
متن کاملExtending XQuery with a Pattern Matching Facility
Considering the growing usage of XML for communication and data representation, the need for more advanced analytical capabilities on top of XQuery is emerging. In this regard, a pattern matching facility can be considered as a natural extension to empower XQuery. In this paper we first provide some use cases for XML pattern matching. After showing that current XQuery falls short in meeting bas...

The growing interest toward XML leaded to the definition of many querying and manipulating tools, such as the standard query language XQuery [3]. Unlike SQL, X...
متن کاملEfficient Evaluation of XQuery over Streaming Data
With the growing popularity of XML and emergence of streaming data model, processing queries over streaming XML has become an important topic. This paper presents a new framework and a set of techniques for processing XQuery over streaming data. As compared to the existing work on supporting XPath/XQuery over data streams, we make the following three contributions: 1. We propose a series of opt...
متن کاملAssociation Rule Mining from XML Data
With the growing usage of XML in the World Wide Web and elsewhere as a standard for the exchange of data and to represent semistructured data, there is an imminent need for tools and techniques to perform data mining on XML documents and XML repositories. In this paper we look at the various approaches for association rule mining from XML data. We present a Java-based implementation of the Apri...
