It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL).

  • Document Object Model
    Document Object Model DOM DOM is a programming interface that provides a way for the values and structure of an XML document to be accessed and manipulated. Tasks that can be performed with DOM . Navigate an XML document's structure, which is a tree stored in memory. Report the information found at the nodes of the XML tree. Add, delete, or modify elements in the XML document. DOM represents each node of the XML tree as an object with properties and behavior for processing the XML. The root of the tree is a Document object. Its children represent the entire XML document except the xml declaration. On the next page we consider a small XML document with comments, a processing instruction, a CDATA section, entity references, and a DOCTYPE declaration, in addition to its element tree. It is valid with respect to a DTD, named root.dtd. <!ELEMENT root (child*)> <!ELEMENT child (name)> <!ELEMENT name (#PCDATA)> <!ATTLIST child position NMTOKEN #REQUIRED> <!ENTITY last1 "Dover"> <!ENTITY last2 "Reckonwith"> Document Object Model Copyright 2005 by Ken Slonneger 1 Example: root.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE root SYSTEM "root.dtd"> <!-- root.xml --> <?DomParse usage="java DomParse root.xml"?> <root> <child position="first"> <name>Eileen &last1;</name> </child> <child position="second"> <name><![CDATA[<<<Amanda>>>]]> &last2;</name> </child> <!-- Could be more children later. --> </root> DOM imagines that this XML information has a document root with four children: 1. A DOCTYPE declaration. 2. A comment. 3. A processing instruction, whose target is DomParse. 4. The root element of the document. The second comment is a child of the root element.

  • Extensible Markup Language (XML) and Its Role in Supporting the Global Justice XML Data Model
    Extensible Markup Language (XML) and Its Role in Supporting the Global Justice XML Data Model Extensible Markup Language, or "XML," is a computer programming language designed to transmit both data and the meaning of the data. XML accomplishes this by being a markup language, a mechanism that identifies different structures within a document. Structured information contains both content (such as words, pictures, or video) and an indication of what role content plays, or its meaning. XML identifies different structures by assigning data "tags" to define both the name of a data element and the format of the data within that element. Elements are combined to form objects. An XML specification defines a standard way to add markup language to documents, identifying the embedded structures in a consistent way. By applying a consistent identification structure, data can be shared between different systems, up and down the levels of agencies, across the nation, and around the world, with the ease of using the Internet. In other words, XML lays the technological foundation that supports interoperability. XML also allows structured relationships to be defined. The ability to represent objects and their relationships is key to creating a fully beneficial justice information sharing tool. A simple example can be used to illustrate this point: A "person" object may contain elements like physical descriptors (e.g., eye and hair color, height, weight), biometric data (e.g., DNA, fingerprints), and social descriptors (e.g., marital status, occupation). A "vehicle" object would also contain many elements (such as description, registration, and/or lien-holder). The relationship between these two objects—person and vehicle— presents an interesting challenge that XML can address.

  • An XML Model of CSS3 As an XƎL ATEX-TEXML-HTML5 Stylesheet
    An XML model of CSS3 as an XƎLATEX-TEXML-HTML5 stylesheet language S. Sankar, S. Mahalakshmi and L. Ganesh TNQ Books and Journals Chennai Abstract HTML5[1] and CSS3[2] are popular languages of choice for Web development. However, HTML and CSS are prone to errors and difficult to port, so we propose an XML version of CSS that can be used as a standard for creating stylesheets and tem- plates across different platforms and pagination systems. XƎLATEX[3] and TEXML[4] are some examples of XML that are close in spirit to TEX that can benefit from such an approach. Modern TEX systems like XƎTEX and LuaTEX[5] use simplified fontspec macros to create stylesheets and templates. We use XSLT to create mappings from this XML-stylesheet language to fontspec-based TEX templates and also to CSS3. We also provide user-friendly interfaces for the creation of such an XML stylesheet. Style pattern comparison with Open Office and CSS Now a days, most of the modern applications have implemented an XML package format that includes an XML implementation of stylesheet: InDesign has its own IDML[6] (InDesign Markup Language) XML package format and MS Word has its own OOXML[7] format, which is another ISO standard format. As they say ironically, the nice thing about standards is that there are plenty of them to choose from. However, instead of creating one more non-standard format, we will be looking to see how we can operate closely with current standards. Below is a sample code derived from OpenOffice document format: <style:style style:name=”Heading_20_1” style:display-name=”Heading

  • Development and Maintenance of Xml-Based Versus Html-Based Websites: a Case Study
    DEVELOPMENT AND MAINTENANCE OF XML-BASED VERSUS HTML-BASED WEBSITES: A CASE STUDY Mustafa Atay Department of Computer Science Winston-Salem State University Winston-Salem, NC 27110 USA [email protected] ABSTRACT HTML (Hyper Text Markup Language) has been the primary tool for designing and developing web pages over the years. Content and formatting information are placed together in an HTML document. XML (Extensible Markup Language) is a markup language for documents containing semi-structured and structured information. XML separates formatting from the content. While websites designed in HTML require the formatting information to be included along with the new content when an update occurs, XML does not require adding format information as this information is separately included in XML stylesheets (XSL) and need not be updated when new content is added. On the other hand, XML makes use of extra tags in the XML and XSL files which increase the space usage. In this study, we design and implement two experimental websites using HTML and XML respectively. We incrementally update both websites with the same data and record the change in the size of code for both HTML and XML editions to evaluate the space efficiency of these websites. KEYWORDS XML, XSLT, HTML, Website Development, Space Efficiency 1. INTRODUCTION HTML (Hyper Text Markup Language) [1] has been the primary tool for designing and developing web pages for a long time. HTML is primarily intended for easily designing and formatting web pages for end users. Web pages developed in HTML are unstructured by its nature. Therefore, programmatic update and maintenance of HTML web pages is not an easy task.

Initially, the most widely used embedder is the modern standard web browser (no plug-ins required). Other types of embedders can run on the server (e.g. inside standard Node.js v8 – no add-ons required) or in future there could be more specialist host embedders such as a cross- platform macro-engine inside desktop, mobile or IoT applications.
