Streaming Transformations For XML
Streaming Transformations for XML (STX) is an XML transformation language intended as a high-speed, low memory consumption alternative to XSLT version 1.0 and 2.0. Current work on XSLT 3.0 includes Streaming capabilities. Overview STX is an XML standard for efficient processing of stream-based XML. Basic XSLT is not well suited to stream based processing, and STX fills this niche. Conventional XML processing involves loading the entire XML document into memory for use. In contrast, SAX streams XML events such as "open element," "close element," and "text node" so that other software can begin interpreting information immediately, before the end of the file is reached. Unfortunately some software can't effectively use XML fragments this way and must build up the whole document to begin processing. So is the case with XSLT. Because XSLT's XPath can select any node throughout the document it must have the entire document available in memory. STX only allows queries immediately su ...

XML Transformation Language
An XML transformation language is a programming language designed specifically to transform an ''input'' XML document into an ''output'' document which satisfies some specific goal. There are two special cases of transformation: * XML to XML: the ''output document'' is an XML document. * XML to Data: the ''output document'' is a byte stream. XML to XML As XML to XML transformation outputs an XML document, XML to XML transformation chains form XML pipelines. XML to Data The XML (EXtensible Markup Language) to Data transformation contains some important cases. The most notable one is XML to HTML (HyperText Markup Language), as an HTML document ''is not'' an XML document. SGML origins The earliest transformation languages predate the advent of XML as an SGML profile, and thus accept input in arbitrary SGML rather than specifically XML. These include the SGML-to-SGML link process definition (LPD) format defined as part of the SGML standard itself; in SGML (but not XML), the LPD ...

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. These formats can be subsequently converted to 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. 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. The XSLT document transformation specifies how to transform an XML document into new document (usually XML, but other formats, such as plain text are supported). Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used, such as relational database tables or geographical inform ...

Simple API For XML
SAX (Simple API for XML) is an event-driven online algorithm for lexing and 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 The Java implementation of SAX is considered to be normative since there is no formal specification. 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 ...

Streaming XML
In connection-oriented communication, a data stream is the transmission of a sequence of digitally encoded signals to convey information. Typically, the transmitted symbols are grouped into a series of packets. Data streaming has become ubiquitous. Anything transmitted over the Internet is transmitted as a data stream. Using a mobile phone to have a conversation transmits the sound as a data stream. Formal definition In a formal way, a data stream is any ordered pair ( s, \Delta ) where: # s is a sequence of tuples and # \Delta is a sequence of positive real time intervals. Content Data Stream contains different sets of data, that depend on the chosen data format. * Attributes – each attribute of the data stream represents a certain type of data, e.g. segment / data point ID, timestamp, geodata. * Timestamp attribute helps to identify when an event occurred. * Subject ID is an encoded-by-algorithm ID, that has been extracted out of a cookie. * Raw Data include ...

XPath
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, and can be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document. Support for XPath exists in applications that support XML, such as web browsers, and many programming languages. The XPath language is based on a tree representation of the XML document, and provides the ability to navigate around the tree, selecting nodes by a variety of criteria. In popular use (though not in the official specification), an XPath expression is often referred to simply as "an XPath". Originally motivated by a desire to provide a common syntax and behavior model between XPointer and XSLT, subsets of the XPath query language are used in other W3C specifications such as XML Schema, XForms and the Internationalization Tag Set (ITS). XPath has been adopted by a num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XPath 2
XPath 2.0 is a version of the XPath language defined by the World Wide Web Consortium, W3C. It became a recommendation on 23 January 2007. As a W3C Recommendation it was superseded by XPath 3.0 on 10 April 2014. XPath is used primarily for selecting parts of an XML document. For this purpose the XML document is modelled as a tree of nodes. XPath allows nodes to be selected by means of a hierarchic navigation path through the document tree. The language is significantly larger than its predecessor, XPath 1.0, and some of the basic concepts such as the data model and type system have changed. The two language versions are therefore described in separate articles. XPath 2.0 is used as a sublanguage of XSLT 2.0, and it is also a subset of XQuery 1.0. All three languages share the same data model (the XDM), type system, and function library, and were developed together and published on the same day. Data model Every value in XPath 2.0 is a ''sequence'' of ''items''. The item ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perl
Perl is a high-level, general-purpose, interpreted, dynamic programming language. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Perl originally was not capitalized and the name was changed to being capitalized by the time Perl 4 was released. The latest release is Perl 5, first released in 1994. From 2000 to October 2019 a sixth version of Perl was in development; the sixth version's name was changed to Raku. Both languages continue to be developed independently by different development teams which liberally borrow ideas from each other. Perl borrows features from other programming languages including C, sh, AWK, and sed. It provides text processing facilities without the arbitrary data-length limits of ...

Callback (computer Science)
In computer programming, a callback is a Function (computer programming), function that is stored as data (a Reference (computer science), reference) and designed to be called by another function often ''back'' to the original Abstraction (computer science), abstraction layer. A function that accepts a callback Parameter (computer programming), parameter may be designed to call back before Return statement, returning to its caller which is known as ''Synchronization (computer science), synchronous'' or ''blocking''. The function that accepts a callback may be designed to store the callback so that it can be called back after returning which is known as ''asynchronous'', ''Non-blocking algorithm, non-blocking'' or ''deferred''. Programming languages support callbacks in different ways such as function pointers, Lambda (programming), lambda expressions and block (programming), blocks. A callback can be likened to leaving instructions with a tailor for what to do when a suit is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
