Design and application of an XML data compression algorithm based on Huffman coding
Zhao Li · Journal of Beijing University of Chemical Technology · 2013
An XML data compression method based on Huffman coding has been proposed for the problem where the accessing rate of a production process report system for a large data source is not high in a certain bandwidth.A data processing class was constructed for XML documents to get a high rate word units in this algorithm.With the help of Huffman coding to code specific unit words,the coded document was compressed by the LZMA compression algorithm.The problem of needing the assistance of the document type definition and XML parser in the traditional XML data compression algorithm was solved using this algorithm,which resulted in a good compression effect.The Huffman-LZMA compression algorithm was constructed and was applied to the production process report system design.The experimental compression ratio of the report data reached about 88%.The bandwidth and storage space were saved effectively,and the report accessing rate was improved.
