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. -

W3C liability, trademark and document use rules apply. Abstract The current Web is primarily made up of an enormous number of documents that have been created using HTML. These documents contain significant amounts of structured data, which is largely unavailable to tools and applications. When publishers can express this data more completely, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience: an event on a web page can be directly imported - 1 - How to Read this Document RDFa in XHTML: Syntax and Processing into a user’s desktop calendar; a license on a document can be detected so that users can be informed of their rights automatically; a photo’s creator, camera setting information, resolution, location and topic can be published as easily as the original photo itself, enabling structured search and sharing. -

Exploring and Extracting Nodes from Large XML Files
Exploring and Extracting Nodes from Large XML Files Guy Lapalme January 2010 Abstract This article shows how to deal simply with large XML files that cannot be read as a whole in memory and for which the usual XML exploration and extraction mechanisms cannot work or are very inefficient in processing time. We define the notion of a skeleton document that is maintained as the file is read using a pull- parser. It is used for showing the structure of the document and for selecting parts of it. 1 Introduction XML has been developed to facilitate the annotation of information to be shared between computer systems. Because it is intended to be easily generated and parsed by computer systems on all platforms, its format is based on character streams rather than internal binary ones. Being character-based, it also has the nice property of being readable and editable by humans using standard text editors. XML is based on a uniform, simple and yet powerful model of data organization: the generalized tree. Such a tree is defined as either a single element or an element having other trees as its sub-elements called children. This is the same model as the one chosen for the Lisp programming language 50 years ago. This hierarchical model is very simple and allows a simple annotation of the data. The left part of Figure 1 shows a very small XML file illustrating the basic notation: an arbitrary name between < and > symbols is given to a node of a tree. This is called a start-tag. -

WEB-BASED ANNOTATION and COLLABORATION Electronic Document Annotation Using a Standards-Compliant Web Browser
WEB-BASED ANNOTATION AND COLLABORATION Electronic Document Annotation Using a Standards-compliant Web Browser Trev Harmon School of Technology, Brigham Young University, 265 CTB, Provo, Utah, USA Keywords: Annotation, collaboration, web-based, e-learning. Abstract: The Internet provides a powerful medium for communication and collaboration through web-based applications. However, most web-based annotation and collaboration applications require additional software, such as applets, plug-ins, and extensions, in order to work correctly with the web browsers typically found on today’s computers. This in combination with the ever-growing number of file formats poses an obstacle to the wide-scale deployment of annotation and collaboration systems across the heterogeneous networks common in the academic and corporate worlds. In order to address these issues, a web-based system was developed that allows for freeform (handwritten) and typed annotation of over twenty common file formats via a standards-compliant web browser without the need of additional software. The system also provides a multi-tiered security architecture that allows authors control over who has access to read and annotate their documents. While initially designed for use in academia, flexibility within the system allows it to be used for many annotation and collaborative tasks such as distance-learning, collaborative projects, online discussion and bulletin boards, graphical wikis, and electronic grading. The open-source nature of the system provides the opportunity for its continued development and extension. 1 INTRODUCTION did not foresee the broad spectrum of uses expected of their technologies by today’s users. While serving While the telegraph and telephone may have cracked this useful purpose, such add-on software can open the door of instantaneous, worldwide become problematic in some circumstances because communication, the Internet has flung it wide open. -
Document Object Model
Document Object Model CITS3403: Agile Web Development Semester 1, 2021 Introduction • We’ve seen JavaScript core – provides a general scripting language – but why is it so useful for the web? • Client-side JavaScript adds collection of objects, methods and properties that allow scripts to interact with HTML documents dynamic documents client-side programming • This is done by bindings to the Document Object Model (DOM) – “The Document Object Model is a platform- and language-neutral interface that will allow programs and scripts to dynamically access and update the content, structure and style of documents.” – “The document can be further processed and the results of that processing can be incorporated back into the presented page.” • DOM specifications describe an abstract model of a document – API between HTML document and program – Interfaces describe methods and properties – Different languages will bind the interfaces to specific implementations – Data are represented as properties and operations as methods • https://www.w3schools.com/js/js_htmldom.asp The DOM Tree • DOM API describes a tree structure – reflects the hierarchy in the XTML document – example... <html xmlns = "http://www.w3.org/1999/xhtml"> <head> <title> A simple document </title> </head> <body> <table> <tr> <th>Breakfast</th> <td>0</td> <td>1</td> </tr> <tr> <th>Lunch</th> <td>1</td> <td>0</td> </tr> </table> </body> </html> Execution Environment • The DOM tree also includes nodes for the execution environment in a browser • Window object represents the window displaying a document – All properties are visible to all scripts – Global variables are properties of the Window object • Document object represents the HTML document displayed – Accessed through document property of Window – Property arrays for forms, links, images, anchors, … • The Browser Object Model is sometimes used to refer to bindings to the browser, not specific to the current page (document) being rendered.
