A divergence betwixt SAX as well as DOM Parser is real pop Java interview as well as ofttimes asked when interviewed on Java as well as XML. Both DOM as well as SAX parser are extensively used to read as well as parse XML file inward java as well as own got their ain ready of payoff as well as disadvantage which nosotros volition comprehend inward this article. Though at that spot is roughly other agency of reading XML file using XPath inward 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 too ofttimes viewed inward damage of speed, retentivity consumption as well as their might to procedure large XML files.
Difference betwixt DOM as well as SAX XML Parser inward Java
DOM XML Parser inward Java DOM Stands for Document Object Model as well as it stand upwards for an XML Document into tree format which each chemical cistron representing tree branches. DOM Parser creates an In Memory tree representation of XML file as well as and thence parses it, thence it requires to a greater extent than retentivity as well as it's advisable to own got increased the heap size for DOM parser inward lodge to avoid Java.lang.OutOfMemoryError:java heap space .
Parsing XML file using DOM parser is quite fast if XML file is modest but if you lot endeavour to read a large XML file using DOM parser at that spot is to a greater extent than chances that it volition own got a long fourth dimension or fifty-fifty may non live on able to charge it completely exactly because it requires lot of retentivity to exercise XML Dom Tree. Java provides back upwards DOM Parsing as well as you lot tin parse XML files inward Java using DOM parser. DOM classes are inward w3c.dom packet piece DOM Parser for Java is inward JAXP (Java API for XML Parsing) package.

SAX XML Parser inward Java
SAX Stands for Simple API for XML Parsing. This is an result based XML Parsing as well as it parse XML file measuring yesteryear step thence much suitable for large XML Files. SAX XML Parser fires an result when it encountered opening tag, chemical cistron or attribute, as well as the parsing industrial plant accordingly. It’s recommended to use SAX XML parser for parsing large XML files inward Java because it doesn't require to charge whole XML file inward Java as well as it tin read a large XML file inward modest parts. Java provides back upwards for SAX parser as well as you lot tin parse whatsoever XML file inward Java using SAX Parser, I own got covered an event of reading XML file using SAX Parser here. One disadvantage of using SAX Parser inward coffee is that reading XML file inward Java using SAX Parser requires to a greater extent than code inward comparing of DOM Parser.
Difference betwixt DOM as well as SAX XML Parser
Here are few high-level differences betwixt DOM parser as well as SAX Parser in Java:
1) DOM parser loads whole XML document inward retentivity piece SAX alone loads a modest business office of the XML file inward memory.
2) DOM parser is faster than SAX because it access whole XML document inward memory.
3) SAX parser inward Java is ameliorate suitable for large XML file than DOM Parser because it doesn't require much memory.
4) DOM parser industrial plant on Document Object Model piece SAX is an result based XML parser.
That’s all on the difference betwixt SAX as well as DOM parsers inward Java, immediately it’s upwards to you lot on which XML parser you lot going to choose. I recommend using DOM parser over SAX parser if XML file is modest plenty as well as become amongst SAX parser if you lot don’t know the size of XML files to live on processed or they are large.
