Distinction between DOM and SAX XML Parser in Java
Now let see some key variations between each DOM and SAX parser whereas parsing or studying XML information in Java.
1. DOM XML Parser in Java
Parsing XML file utilizing DOM parser is sort of quick if the XML file is small however in case you attempt to learn a big XML file utilizing DOM parser there are extra probabilities that it’ll take a very long time and even could not have the ability to load it fully just because it requires a whole lot of reminiscence to create XML Dom Tree.
Java supplies assist DOM Parsing and you’ll parse XML information in Java utilizing DOM parser. DOM lessons are in w3c.dom bundle whereas DOM Parser for Java is in JAXP (Java API for XML Parsing) bundle.
2. SAX XML Parser in Java
SAX Stands for Easy API for XML Parsing. That is an occasion based mostly XML Parsing and it parse XML file step-by-step a lot appropriate for giant XML Recordsdata. SAX XML Parser fires an occasion when it encountered opening tag, factor or attribute, and the parsing works accordingly.
It’s really helpful to use SAX XML parser for parsing giant XML information in Java as a result of it does not require loading the entire XML information in Java and it could actually learn a giant XML file in small elements.
Java supplies assist for SAX parser and you’ll parse any XML file in Java utilizing SAX Parser, I’ve lined an instance of studying XML file utilizing SAX Parser right here. One drawback of utilizing SAX Parser in java is that studying XML information in Java utilizing SAX Parser requires extra code compared to DOM Parser.
Distinction between DOM and SAX XML Parser
Listed here are a number of high-level variations between DOM parser and SAX Parser in Java:
1) DOM parser masses complete XML paperwork in reminiscence whereas SAX solely masses a small a part of the XML file in reminiscence.
2) DOM parser is quicker than SAX as a result of it accesses the entire XML doc in reminiscence.
3) SAX parser in Java is healthier appropriate for a big XML file than DOM Parser as a result of it does not require a lot reminiscence.
4) DOM parser works on Doc Object Mannequin whereas SAX is an event-based XML parser.
Here’s a good diagram which spotlight not simply distinction between DOM and SAX parser but in addition Stax parser:
That’s all on the distinction between SAX and DOM parsers in Java, now it’s as much as you on which XML parser you going to decide on. I like to recommend utilizing DOM parser over SAX parser if the XML file is sufficiently small and go together with SAX parser in case you don’t know the scale of XML information to be processed or they’re giant.Java Tutorial you might like:
