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 ...
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.
Streaming API for XML (StAX) is an application programming interface to read and write XML documents, originating from the Java programming language community. Traditionally, XML APIs are either: DOM based - the entire document is read into memory as a tree structure for random access by the calling application
Stream-oriented APIs accessible from a programming language, for example SAX and StAX. Tree-traversal APIs accessible from a programming language, for example DOM. XML data binding, which provides an automated translation between an XML document and programming-language objects. Declarative transformation languages such as XSLT and XQuery.
For example, 3.14 will be serialized to 3.140 000 000 000 000 124 344 978 758 017 532 527 446 746 826 171 875. ^ XML data bindings and SOAP serialization tools provide type-safe XML serialization of programming data structures into XML. Shown are XML values that can be placed in XML elements and attributes.
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 ...
XML documents typically refer to external entities, for example the public and/or system ID for the Document Type Definition. These external relationships are expressed using URIs, typically as URLs. However absolute URLs only work when the network can reach them.
This allows applications to access the data in the XML from the object, rather than using the DOM or SAX to retrieve the data from a direct representation of the XML itself. It makes it possible to read and write XML data using a programming language class library (e.g. C++, C#, Java), specifically created for a given XML data format. [1]
