While the volume of XML data and sometimes even the processing time of XML data can be reduced by using XML compression and storing, processing, and transferring compressed XML instead of uncompressed XML, a transformation of the transferred XML data into the receiver's XML format via XQuery cannot be performed on the compressed XML data directly. Instead, XQuery transformation of compressed XML data requires a prior decompression. In this paper, we present a generic approach to transform compressed or uncompressed XML representations that support basic navigation and update as well as optional copy functionalities. In a series of experiments, we have shown that using our approach to transform compressed XML is not only faster than the indirect approach via decompression, XQuery transformation, and recompression, but also that our approach transforms compressed XML as efficient as other XQuery evaluators transform uncompressed XML only.
