Most XML presentations try to clarify when to use XML instead of HTML (generic, normal internet websites), an approach most readily grasped by those who already have some HTML authoring knowledge. Other tools aimed at introducing XML to novices, such as the Text Encoding Initiative (TEI) Gentle approach to XML, go beyond simply explaining why humanities academics might want to use XML and what an XML document looks like, both aiming to place XML in a particular sense of markup languages and introducing the syntax of the structured schema languages used to model them. For XHTML output, the single DITA topic file is the translation unit for the files included in a DITA map. it is possible to convert text in the file and to trigger the DITA Open Toolkit to edit any character sequences that it places in the output, such as the string "Related connections" in XHTML.
XML model formal
This is a formal model centered on a hierarchy arranged or, in technical terms, a tree. It consists of a root (which contains everything else), the components under the root, which contain their own subcomponents, etc. These are called nodes, these elements and subcomponents. In the case of our book example, the root node is the book, it may contain a title-page node, followed by a table-of-content node (which contains nodes for each of the listed content items, in order, and each of them may contain two nodes, one for the table-of-content entry and the other for the page reference). All this is done with php web development.
How DITA Open Toolkit processing handles localization for XHTML output
When it processes a topic, the Toolkit uses the xml:lang value in each topic element to determine how to do string substition and to flow text (for example, left to right or right to left). If no xml: lang attribute is specified, it follows the ancestor chain of the current topic to determine xml: lang from any containing element. If none is found, the default language is used.
