Abstract

Whenever XML is used as the data format to exchange large amounts of data or even for data streams, the verbose behavior of XML is one of the bottle necks. While compression of XML data seems to be a way out, it is essential for a variety of applications that the compression result still can be parsed, searched, transformed or modified efficiently. In order to support efficient search in compressed XML data, we have devel oped a compression technique that links two components: the first component uses the DTD to perform a structure-preserving compression of XML markup data, while the second uses a trie for the compression of text constants and attribute values.
