Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.
XSLT is a language 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. XSLT 1.0 is widely supported in modern web browsers.
The Java programming language XML APIs developed by Sun Microsystems consist of the following separate computer-programming APIs:
In software, an XML pipeline is formed when XML processes, especially XML transformations and XML validations, are connected.
Schematron is a rule-based validation language for making assertions about the presence or absence of patterns in XML trees. It is a structural schema language expressed in XML using a small number of elements and XPath.
XForms is an XML format used for collecting inputs from web forms. XForms was designed to be the next generation of HTML / XHTML forms, but is generic enough that it can also be used in a standalone manner or with presentation languages other than XHTML to describe a user interface and a set of common data manipulation tasks.
Saxon is an XSLT and XQuery processor created by Michael Kay and now developed and maintained by his company, Saxonica. There are open-source and also closed-source commercial versions. Versions exist for Java, JavaScript and .NET.
The Apache XML project is part of the Apache Software Foundation and focuses on XML-related projects.
eXist-db is an open source software project for NoSQL databases built on XML technology. It is classified as both a NoSQL document-oriented database system and a native XML database. Unlike most relational database management systems (RDBMS) and NoSQL databases, eXist-db provides XQuery and XSLT as its query and application programming languages.
The identity transform is a data transformation that copies the source data into the destination data without change.
The Oxygen XML Editor is a multi-platform XML editor, XSLT/XQuery debugger and profiler with Unicode support. It is a Java application, so it can run in Windows, Mac OS X, and Linux. It also has a version that can run as an Eclipse plugin.
XProc is a W3C Recommendation to define an XML transformation language to define XML Pipelines.
XPath is a query language for selecting nodes from an XML document. In addition, XPath may be used to compute values from the content of an XML document. XPath was defined by the World Wide Web Consortium (W3C).
In software development XRX is a web application architecture based on XForms, REST and XQuery. XRX applications store data on both the web client and on the web server in XML format and do not require a translation between data formats. XRX is considered a simple and elegant application architecture due to the minimal number of translations needed to transport data between client and server systems. The XRX architecture is also tightly coupled to W3C standards to ensure XRX applications will be robust in the future. Because XRX applications leverage modern declarative languages on the client and functional languages on the server they are designed to empower non-developers who are not familiar with traditional imperative languages such as JavaScript, Java or .Net.
XQuery is a query and functional programming language that queries and transforms collections of structured and unstructured data, usually in the form of XML, text and with vendor-specific extensions for other data formats. The language is developed by the XML Query working group of the W3C. The work is closely coordinated with the development of XSLT by the XSL Working Group; the two groups share responsibility for XPath, which is a subset of XQuery.
Google Closure Tools is a set of tools to help developers build rich web applications with JavaScript. It was developed by Google for use in their web applications such as Gmail, Google Docs and Google Maps.
XQuery API for Java (XQJ) refers to the common Java API for the W3C XQuery 1.0 specification.
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.
Diazo, previously named xdv, is a general-purpose, open source website theming tool. It is written in Python and generates XSLT. Diazo creates a separation between theme pages and transformation rules, allowing web designers to work on templates in plain HTML, without knowledge of XSLT or special template-related codes.
srcML is a document-oriented XML representation of source code. It was created in a collaborative effort between Michael L. Collard and Jonathan I. Maletic. The abbreviation, srcML, is short for Source Markup Language. srcML wraps source code (text) with information from the Abstract Syntax Tree or AST (tags) into a single XML document. All original text is preserved so that the original source code document can be recreated from the srcML markup. The only exception is the possibility of newline normalization.
