SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM). Where the DOM operates on the document as a whole—building the full abstract syntax tree of an XML document for convenience of the user—SAX parsers operate on each piece of the XML document sequentially ...
Because of VTD-XML's performance and memory advantages, it covers a larger portion of XML use cases than either DOM or SAX. [18] Compared to DOM, VTD-XML processes bigger (3x~5x) XML documents for the same amount of physical memory at about 3 to 10 times the performance. Compared to SAX, VTD-XML provides random access and XPath support and ...
StAX was designed as a median between these two opposites. In the StAX metaphor, the programmatic entry point is a cursor that represents a point within the document. The application moves the cursor forward - 'pulling' the information from the parser as it needs.

The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.
Angular 2.0 was announced at the ng-Europe conference 22–23 October 2014. [16] On April 30, 2015, the Angular developers announced that Angular 2 moved from Alpha to Developer Preview. [17] Angular 2 moved to Beta in December 2015, [18] and the first release candidate was published in May 2016. [19] The final version was released on 14 ...
The DOM that the browser constructs is what it then uses to render the page for display to the user. The DOM of a webpage needs to be distinguished from its markup because of client-side scripting (usually JavaScript). The initial DOM constructed from the markup can serve as the target of scripts. The elements of the DOM can be manipulated by ...
The framework can then find the differences between the previous virtual DOM and the current one (diffing), and only makes the necessary changes to the actual DOM (reconciliation). [ 2 ] [ 3 ] While technically slower than using just vanilla JavaScript, the pattern makes it much easier to write websites with a lot of dynamic content, since ...
