What is XML? what are XML element and attributes?
XML is a universal metalanguage used to define other Web services standards,
protocol, interfaces, documents, and data. It is made of plain-text and self-describing.
XML elements are used to define the data that are integral to the document.
XML attributes are used to define out-of-band data which give additional information.
XML is
1. a Meta language that can be used to define another language.
2. a standard for data representation
XML is often used for defining
- data structures
- communication protocols
What is required for a well-formed XML document?
- unique root element
- each element has opening/closing tags
- no overlapped tags
Which of the following is NOT true about XML?
,A) XML tags are case-sensitive
B) Every well-formed XML document needs to have a root node
C) XML elements can't be empty
D) Every opening tag must have a closing tag
C) XML elements can't be empty
An XML document can be best illustrated as...
a rooted tree
What type of file does the following piece of code most likely belong to?
<Book>
<Title>Introduction to Programming Language</Title>
<Author>Yinong Chen</Author>
<Year>2006</Year>
<ISBN>0-7575-2974-7</ISBN>

XML instance file
Which of the following conform with the XML syntax?

- <image></ image >
- <image />
- <image source = "Photo.jpeg" />

What namespace inherits and merges all names from other namespaces into the
current schema?
targetNamespace
, what is an XML namespace?
how is a namespace defined?
why is it useful?
Binds a prefix name (qualifier) to a schema definition and then uses that prefix
whenever required.
Declared as an attribute of an element.
Used to limit the scope of a name of a DTD or schema to eliminate conflict.
What is the purpose of defining a default namespace in an XML file?
To reduce the use of a namespace qualifier prefixed to the element names
An attribute with an element...
is never implicitly qualified by the qualifier of the element
What would happen if the same namespace qualifier is declared in the root and in
a child element?
the inner declaration will override the outer one.
Which of the followings are valid for representing the expression: 0 < x < 10 in an
XML element? Select all that apply.
a) 0 < x < 10
b) 0 < x < 10
c) 0 #60; x #60; 10
d) 0 "<" x "<" 10
