There can be other XML nodes outside of the root element. [4] In particular, the root element may be preceded by a prolog, which itself may consist of an XML declaration, optional comments, processing instructions and whitespace, followed by an optional DOCTYPE declaration and more optional comments, processing instructions and whitespace.
The begin, end, and empty-element tags that delimit the elements are correctly nested, with none missing and none overlapping; A single "root" element contains all the other elements; These features resemble those of trees, in that there is a single root node, and an order to the elements. XML has appeared as a first-class data type in other ...
The next column shows attributes of root elements and every unique first child of the root XML element. If the root element has six children named "section," then the grid view will show only one section element and a notation that there are six of them. This iteration continues for the next column.

Form, link and image elements could be referenced with a hierarchical name that began with the root document object. A hierarchical name could make use of either the names or the sequential index of the traversed elements. For example, a form input element could be accessed as either document.myForm.myInput or document.forms[0].elements[0].
If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element). This similar diagnostic occurs if an article contains multiple invocations of {{ ref }} with the same ID, for example, two instances of " {{ref|1|1}} ".

Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
