In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.
The Template Attribute Language (TAL) is a templating language used to generate dynamic HTML and XML pages. Its main goal is to simplify the collaboration between programmers and designers. This is achieved by embedding TAL statements inside valid HTML (or XML) tags which can then be worked on using common design tools.
XML namespaces are used for providing uniquely named elements and attributes in an XML document. They are defined in a W3C recommendation. [1] [2] An XML instance may contain element or attribute names from more than one XML vocabulary. If each vocabulary is given a namespace, the ambiguity between identically named elements or attributes can ...
A QName, or qualified name, is the fully qualified name of an element, attribute, or identifier in an XML document. A QName concisely associates the URI of an XML namespace with the local name of an element, attribute, or identifier in that namespace. [1] To make this association, the QName assigns the local name a prefix that corresponds to ...
In XML, the XML namespace specification enables the names of elements and attributes in an XML document to be unique, similar to the role of namespaces in programming languages. Using XML namespaces, XML documents may contain element or attribute names from more than one XML vocabulary.
Code that uses this iterator can test the current item (to tell, for example, whether it is a start-tag or end-tag, or text), and inspect its attributes (local name, namespace, values of XML attributes, value of text, etc.), and can also move the iterator to the next item. The code can thus extract information from the document as it traverses it.
The qualified name of an element. It must conform to naming rules of XML objects. (i.e. must start with a letter or underscore, case-sensitive, cannot start with the letters xml(in any case), can contain letters, digits, hyphens, underscores, and periods, cannot contain spaces.) Expanded-QName The fully qualified name of an element.
Again the properties include the attribute name and target namespace. The attribute type constrains the values that the attribute may take. An attribute declaration may also include a default value or a fixed value (which is then the only value the attribute may take.) Simple and complex types. These are described in the following section ...
