Element a (b, c 5) Elements containing character data can be declared as containing only character data! Element a pcdata) or as containing a mixture of character data and elements in any order! Element a pcdata b c in the latter case, the declaration must place pcdata first in the group, the group must be a choice, and the group must appear zero or more times. Such groups are generally referred to as "mixed content" (as opposed to element-only groups or "element content. Technically, mixed content refers to any element containing character data. However, in common usage it refers only to the latter case. Note: "pcdata" in the declarations is short for "Parsed Character data". The term is inherited from sgml and comes from the fact that the text in the xml document following the element tag is parsed looking for more markup tags.

For example: Sequence:!- element A consists like of a single element. Element a (B)!- element A consists of element B followed by element. Element a (b, c)!- element A consists of a sequence, including a choice subgroup. Element a (B, (c d e choice:!- element A consists of either element b or element. Element a (b c)!- element A consists of a choice, including a sequence subgroup. Element a (b c (d, e) presentation 4) Optional? one-or-more and zero-or-more operators can be applied to groups, subgroups, and subelements. For example: Optional:!- subelement b is optional. Element a (B?, C) One or more:!- subgroup (c d) occurs one or more times. Element a (B, (c d e) zero or more:!- group (b, c) occurs zero or more times,. A can be empty.

Elements defined as character data, empty, or any constitute terminals. For example:!- element a is a non-terminal. Element a (B)!- element b is a terminal. Element b pcdata) Although it is legal to define a language containing non-terminals that never resolve to terminals, such as one with purely circular definitions, it is generally impossible and/or useless to create any valid documents for such languages. 3) Groups can be either a sequence or choice of subelements and/or subgroups.outsiders
For example, if we defined a grammar for the book language, authors using this grammar could use a validating parser to ensure that their documents conformed to the language. An xml markup language is defined in a document Type definition (DTD). The dtd is either contained in a! Doctype tag, contained in an the external file and referenced from a! Doctype tag, or both. For example, the document shown above could contain the following! Element book (Title, chapter)! Attlist book author cdata required!
Although it is longer than chapter 1, it is not any more interesting. Chapter /book the names of the elements and attributes and their order in the hierarchy (among other things) form the xml markup language used by the document. This language can be defined by the document author or it can be inferred from the document's structure. In the example shown above, the language contains three elements: book, title, and Chapter. The book element contains a single title element and one or more Chapter elements. The book element has an Author attribute and the Chapter element has an id attribute. The main reason to explicitly define the language is so that documents can be checked to conform.

Xml specification or the thesis annotated xml specification. Note: The examples below often redefine the same element. This is for simplicity only; it is an error to define an element more than once in an actual dtd. Xml markup Languages, an xml document primarily consists of a strictly nested hierarchy of elements with a single root. Elements can contain character data, child elements, or a mixture of both.
In addition, they can have attributes. Child character data and child elements are strictly ordered; attributes are not. book author"Anonymous" title sample book /Title chapter id"1" This is chapter. It is not very long or interesting. Chapter chapter id"2" This is chapter.
