The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree.
[1] For example, C++ is a multi-paradigm language including OOP; [2] however, it is less object-oriented than other languages such as Python [3] and Ruby. [ 4 ] Languages with object-oriented features
Consistent coding standards can, in turn, make the measurements more consistent. Special tags within source code comments are often used to process documentation, two notable examples are javadoc and doxygen. The tools specify the use of a set of tags, but their use within a project is determined by convention.
HTML documents imply a structure of nested HTML elements. These are indicated in the document by HTML tags, enclosed in angle brackets thus: < p >. [73] [better source needed] In the simple, general case, the extent of an element is indicated by a pair of tags: a "start tag" < p > and "end tag" </ p >. The text content of the element, if any ...
Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP. PHP supports standard C/C++ style comments, but supports Perl style as well. Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19]
Basically, object code for the language's interpreter needs to be linked into the executable. Source code fragments for the embedded language can then be passed to an evaluation function as strings. Application control languages can be implemented this way, if the source code is input by the user. Languages with small interpreters are preferred.
For example, a "table" element could be defined in a new namespace with new semantics different from the HTML "table" element and the browser will be able to differentiate between the two. In providing namespaces, XHTML combined with CSS allow authoring communities to easily extend the semantic vocabulary of documents.
