A divergence betwixt SAX too DOM Parser is real pop Java interview too oftentimes asked when interviewed on Java too XML. Both DOM too SAX parser are extensively used to read too parse XML file inwards java too possess got their ain prepare of payoff too disadvantage which nosotros volition embrace inwards this article. Though at that topographic point is closed to other agency of reading XML file using XPath inwards Java which is the to a greater extent than selective approach similar SQL statements people tend to stick amongst XML parsers. DOM Parser vs SAX parsers is besides oftentimes viewed inwards damage of speed, retention consumption too their mightiness to procedure large XML files.
Difference betwixt DOM too SAX XML Parser inwards Java
DOM XML Parser inwards Java DOM Stands for Document Object Model too it correspond an XML Document into tree format which each chemical cistron representing tree branches. DOM Parser creates an In Memory tree representation of XML file too hence parses it, hence it requires to a greater extent than retention too it's advisable to possess got increased the heap size for DOM parser inwards corporation to avoid Java.lang.OutOfMemoryError:java heap space .
Parsing XML file using DOM parser is quite fast if XML file is modest but if y'all endeavour to read a large XML file using DOM parser at that topographic point is to a greater extent than chances that it volition possess got a long fourth dimension or fifty-fifty may non move able to charge it completely precisely because it requires lot of retention to practise XML Dom Tree. Java provides back upward DOM Parsing too y'all tin parse XML files inwards Java using DOM parser. DOM classes are inwards w3c.dom packet spell DOM Parser for Java is inwards JAXP (Java API for XML Parsing) package.

SAX XML Parser inwards Java
Difference betwixt DOM too SAX XML Parser
Here are few high-level differences betwixt DOM parser too SAX Parser in Java:
1) DOM parser loads whole XML document inwards retention spell SAX alone loads a modest business office of the XML file inwards memory.
2) DOM parser is faster than SAX because it access whole XML document inwards memory.
3) SAX parser inwards Java is amend suitable for large XML file than DOM Parser because it doesn't require much memory.
4) DOM parser industrial plant on Document Object Model spell SAX is an upshot based XML parser.
That’s all on the difference betwixt SAX too DOM parsers inwards Java, directly it’s upward to y'all on which XML parser y'all going to choose. I recommend using DOM parser over SAX parser if XML file is modest plenty too become amongst SAX parser if y'all don’t know the size of XML files to move processed or they are large.
