ABSTRACT. Bohannon et al. claim that XML is becoming the predominant data exchange format in a variety of application domains. Altinel and Franklin hold that the advent of XML as a standard for information exchange and the development of query languages for XML data enable the development of more sophisticated filtering mechanisms that take structure information into account. Shanmugasundaram et al. develop algorithms and implement a prototype system that converts XML documents to relational tuples, translates semi-structured queries over XML documents to SQL queries over tables, and converts the results to XML. Quint and Vatton review the main innovations of XML and consider their impact on the editing techniques for structured documents.
