Schema Based Parallel XML Parser: A Fast XML Parser Designed for Large XML Files

XML is one of the greatest innovations of the digital world. It has taken the field of Web Technology by storm in the past decade and is becoming an ever-present technology in other fields too. XML with its easy usage has lot of future. But the parsing performance of XML is a big hindrance to its development. Particularly, when dealing with huge XML files, normal XML parsers like DOM, SAX parsers are simply not quick enough. But with the emerging multi-core processors, XML performance can be improved by making the XML parsers run in parallel on different cores of the CPU. There are many parallel XML parser implementations but none of them are designed for extremely large files of sizes greater than 50 Megabytes. This paper presents a new faster XML parallel parser model which improves the parsing performance for these large files.
