Java XML Parser - DOM DOM Parser is the easiest java xml parser to learn. DOM parser loads the XML file into memory and we can traverse it node by node to parse the XML. DOM Parser is good for small files but when file size increases it performs slow and consumes more memory.
The design is inspired by the design of VTD-XML, the fastest XML parser for Java I have seen, being even faster than the StAX and SAX Java standard XML parsers.
DOM4J works with DOM, SAX, XPath, and XSLT. It can parse large XML documents with very low memory footprint.
I have the following problem:
I've got an XML file (approx 1GB), and have to iterate up and down (i.e. not sequential; one after the other) in order to get the required data and do some operations on it. Initially, I used the DOM Java package, but obviously, while parsing through the XML file, the JVM reaches its maximum heap space and halted.
In order to overcome this problem, one of the solutions I came up with, was to find another parser that iterates each element in the XML and then I store it's contents in a temporary SQLite Database on my Hard disk. Hence, in this way, the JVM's heap is not exceeded, and once all data is filled, I ignore the XML file and continue my operations on the temporary SQLite Database.
Is there another way how I can tackle my problem in hand?
