Simple API For XML
SAX (Simple API for XML) is an event-driven online algorithm for parsing XML documents, with an API developed by the XML-DEV mailing list. 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, issuing parsing events while making a single pass through the input stream. Definition Unlike DOM, there is no formal specification for SAX. The Java implementation of SAX is considered to be normative. SAX processes documents state-independently, in contrast to DOM which is used for state-dependent processing of XML documents. Benefits A SAX parser only needs to report each parsing event as it happens, and normally discards almost all of that information once reported (it does, however, keep some ...

Event-driven Programming
In computer programming, event-driven programming is a programming paradigm in which the flow of the program is determined by events such as user actions ( mouse clicks, key presses), sensor outputs, or message passing from other programs or threads. Event-driven programming is the dominant paradigm used in graphical user interfaces and other applications (e.g., JavaScript web applications) that are centered on performing certain actions in response to user input. This is also true of programming for device drivers (e.g., P in USB device driver stacks). In an event-driven application, there is generally a main loop that listens for events and then triggers a callback function when one of those events is detected. In embedded systems, the same may be achieved using hardware interrupts instead of a constantly running main loop. Event-driven programs can be written in any programming language, although the task is easier in languages that provide high-level abstractions, such a ...

XSLT
XSLT (Extensible Stylesheet Language Transformations) is a language originally designed for transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text or XSL Formatting Objects, which may subsequently be converted to other formats, such as PDF, PostScript and PNG. Support for JSON and plain-text transformation was added in later updates to the XSLT 1.0 specification. As of August 2022, the most recent stable version of the language is XSLT 3.0, which achieved Recommendation status in June 2017. XSLT 3.0 implementations support Java, .NET, C/C++, Python, PHP and NodeJS. An XSLT 3.0 Javascript library can also be hosted within the Web Browser. Modern web browsers also include native support for XSLT 1.0. For an XSLT document transformation, the original document is not changed; rather, a new document is created based on the content of an existing one. Typically, input documents are XML files, but anything from which the processo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streaming XML
Streaming XML is a synonym for dynamic data in XML format. Another popular use of this term refers to one method of consuming XML data – largely known as Simple API for XML. This is via asynchronous events that are generated as the XML data is parsed. In this context, the consumer streams through the XML data one item at a time. It does not have anything to do whether the underlying data is being updated via dynamic or static means. Uses * Extensible Messaging and Presence Protocol (XMPP). This is the protocol used for example in Google Talk. * ''QuiXProc'' is an open source Java version of XProc which is streaming and doing parallel processing * ''QuiXPath'' is an open source Java version of XPath which is streaming * ''QuiXSchematron'' is a java version of Schematron which is streaming, developed by INRIA The National Institute for Research in Digital Science and Technology (Inria) () is a French national research institution focusing on computer science and applied m ...

StAX
Streaming API for XML (StAX) is an application programming interface (API) 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 * event based - the application registers to receive events as entities are encountered within the source document. Both have advantages: DOM, for example, allows for random access to the document, and event driven algorithm like SAX has a small memory footprint and is typically much faster. These two access metaphors can be thought of as polar opposites. A tree based API allows unlimited, random access and manipulation, while an event based API is a 'one shot' pass through the source document. 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 ...

MSXML
Microsoft XML Core Services (MSXML) are set of services that allow applications written in JScript, VBScript, and Microsoft development tools to build Windows-native XML-based applications. It supports XML 1.0, DOM, SAX, an XSLT 1.0 processor, XML schema support including XSD and XDR, as well as other XML-related technologies. Overview All MSXML products are similar in that they are exposed programmatically as OLE Automation (a subset of COM) components. Developers can program against MSXML components from C, C++ or from Active Scripting languages such as JScript and VBScript. Managed .NET Interop with MSXML COM components is not supported nor recommended. As with all COM components, an MSXML object is programmatically instantiated by CLSID or ProgID. Each version of MSXML exposes its own set of CLSID's and ProgIDs. For example, to create an MSXML 6.0 DOMDocument object, which exposes the IXmlDomDocument, IXmlDomDocument2, and IXmlDomDocument3 COM interfaces, the ProgID "MS ...

LibXML
libxml2 is a software library for parsing XML documents. It is also the basis for the libxslt library which processes XSLT-1.0 stylesheets. Description Written in the C programming language, libxml2 provides bindings to C++, Ch, XSH, C#, Python, Kylix/Delphi and other Pascals, Ruby, Perl, Common Lisp, and PHP. It was originally developed for the GNOME project, but can be used outside it. libxml2's code is highly portable, since it depends on standard ANSI C libraries only, and it is released under the MIT license. This library was written by Daniel Veillard and receives active feedback from its users. It includes the command-line utility xmllint and an HTML parser.

Java API For XML Processing
In computing, the Java API for XML Processing, or JAXP ( ), one of the Java XML Application programming interfaces, provides the capability of validating and parsing XML documents. It has three basic parsing interfaces: * the Document Object Model parsing interface or DOM interface * the Simple API for XML parsing interface or SAX interface * the Streaming API for XML or StAX interface (part of JDK 6; separate jar available for JDK 5) In addition to the parsing interfaces, the API provides an XSLT interface to provide data and structural transformations on an XML document. JAXP was developed under the Java Community Process as JSR 5 (JAXP 1.0), JSR 63 (JAXP 1.1 and 1.2), and JSR 206 (JAXP 1.3). JAXP version 1.4.4 was released on September 3, 2010. JAXP 1.3 was declareend-of-lifeon February 12, 2008. DOM interface The DOM interface parses an entire XML document and constructs a complete in-memory representation of the document using the classes and modeling the concepts ...

Expat (XML)
Expat is a stream-oriented XML 1.0 parser library, written in C. As one of the first available open-source XML parsers, Expat has found a place in many open-source projects. Such projects include the Apache HTTP Server, Mozilla, Perl, Python and PHP. It is also bound in many other languages. Timeline Software developer James Clark released version 1.0 in 1998 while serving as technical lead on the XML Working Group at the World Wide Web Consortium. Clark released two more versions, 1.1 and 1.2, before turning the project over to a group led by Clark Cooper and Fred Drake in 2000. The new group released version 1.95.0 in September 2000 and continues to release new versions to incorporate bug fixes and enhancements. Availability GitHub hosts the Expat project. Versions exist for most major operating-systems. Deployment To use the Expat library, programs first register handler functions with Expat.

Processing Instruction
A Processing Instruction (PI) is an SGML and XML node type, which may occur anywhere in the document, intended to carry instructions to the application. Processing instructions are exposed in the Document Object Model as Node.PROCESSING_INSTRUCTION_NODE, and they can be used in XPath and XQuery with the 'processing-instruction()' command. Syntax An SGML processing instruction is enclosed within . An XML processing instruction is enclosed within , and contains a ''target'' and optionally some content, which is the node value, that cannot contain the sequence ?>. The XML Declaration at the beginning of an XML document (shown below) is not a processing instruction, however its similar syntax has often resulted in it being referred to as a processing instruction. Examples The most common use of a processing instruction is to request the XML document be rendered using a stylesheet using the 'xml-stylesheet' target, which was standardized in 1999. It can be used for both XSLT a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callback (computer Science)
In computer programming, a callback or callback function is any reference to executable code that is passed as an argument to another piece of code; that code is expected to ''call back'' (execute) the callback function as part of its job. This execution may be immediate as in a synchronous callback, or it might happen at a later point in time as in an asynchronous callback. Programming languages support callbacks in different ways, often implementing them with subroutines, lambda expressions, blocks, or function pointers. Design There are two types of callbacks, differing in how they control data flow at runtime: ''blocking callbacks'' (also known as ''synchronous callbacks'' or just ''callbacks'') and ''deferred callbacks'' (also known as ''asynchronous callbacks''). While blocking callbacks are invoked before a function returns (as in the C example below), deferred callbacks may be invoked after a function returns. Deferred callbacks are often used in the context of I/O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
