.... Structure specific compression methods give much better compression results [4, 15, 14, 46] than conventional compression methods such as the Unix compress utility [52] There exist many XML compressors; we know of XMLZip [12] XMill [36] ICT s XML Xpress [25] Millau [16] XMLPPM [6] XGrind [48], and lossy XML compression [5] We will not perform an exhaustive comparison between our compressor and these compressors, but we will briefly compare our compressor with XMill. Compression ratio. We have performed some initial tests comparing XComprez and XMill. The tests are not ....

....for storing, exchanging and presenting documents, semistructured text databases are becoming the standard. Some techniques to exploit the text structure have been proposed, such as XMill [LS00] and XMLPPM [Che01] However, these are not designed to permit searching the text. Others, like XGrind [TH02] permit searching but do not take advantage of the structure (they just allow it) Our goal in this paper is to explore the possibility of considering the text structure in the context of a compressed text database. We aim at taking advantage of the structure, while still retaining all the ....
....and store XML documents, and its compression approach is not intended for directly supporting querying or updating of the compressed document. XMill is based on the zlib library, which combines Ziv Lempel compression (LZ77 [ZL77] with a variant of Hu man. Another XML compressor is XGrind [TH02] which directly supports queries over the compressed les. An XML document compressed with XGrind retains the structure of the original document, permitting reuse of the standard XML techniques for processing the compressed document. It does not, however, take full advantage of the structure. ....

....of no use for such predicates. For example, when used in a B tree, PIDs allow to answer a query involving a and a path condition in one step. The size of the indexes presented in this paper is small enough to replace an uncompressed XML source by a fully indexed, compressed, and yet queryable [28] source while still saving space. In particular pattern queries without term conditions require an index size of only 2 of the XML source or less. In summary, the major contributions of this work are a new XML node identi cation scheme that encodes complete data paths in combination with a ....

....the document structure is XMill [LS00] developed in AT T Labs. XMill is an XML speci c compressor designed to exchange and store XML documents, and its compression approach is not intended for directly supporting querying or updating of the compressed document. Another XML compressor is XGrind [TH02] which directly supports queries over the compressed les. Other approaches to compress XML data exist, based on the use of a PPM like coder, where the context is given by the path from the root to the tree node that contains the current text. One example is XMLPPM [Che01] which is an adaptive ....
