The growing use of XML mark-up language has made a large amount of heterogeneous XML documents widely available. As the number of applications that utilize heterogeneous XML documents grows, the importance of XML documents transformations increases greatly. A serious obstacle for translating directly between two XML documents, using languages like XSLT, is that a mapping between the two XML representations needs to be carefully specified by a human expert. Current research attempts to address this problem by proposing algorithms to automate aspects of XML schemas matching task. In this paper, we identify two major problems encountered when current matching algorithms are used in the context of XML documents transformations. The first proble...
