A declarative way of extracting XML Data in XSL

Abstract

XML has been accepted as a universal format for data interchange and publication. In applications such as web warehousing, data in XML format (XML data) from the web needs to be extracted and integrated. In this paper, we study extracting XML data from XML data sources in XSL. To avoid the complexities in defining templates in XSL, we define a pattern definition language. Extraction patterns can be defined in the language without dealing with the procedural phase of the XSL language. A defined pattern can be translated to an XSLT query in an automatic manner using the algorithms that we propose in the paper. © Springer-Verlag Berlin Heidelberg 2002.
