SAX versus DOMquestion: Discuss the pros and contras of the SAX approach versus the DOM approach for reading XML data:answer: SAX: + The non-validating, serial access, forward-only processing of XML data is the fastest possibility to access XML resources. + With serial access XML parsing there exists no memory size limit for the XML resource. - Only forward processing no return to elements that were already processed. - Not practicable for XML editing and authoring. DOM: + Practicable for XML editing and authoring. + After the XML representation was loaded, fast access to the elements is possible. - Size of the XML document is limited to the available system memory. |
