QUIZ, CSE 445 EXAM QUESTIONS WITH COMPLETE VERIFIED
AND UPDATED ANSWERS.
what is required for a well-formed XML document?
- unique root element
- each element has opening/closing tags
- no overlapped tags
an XML document can be best illustrated as...
a rooted tree
where can attributes be placed in an XML document?
inside the opening tag of an element
what are CDATA and PCDATA in an XML document?
CDATA will not be checked for syntax errors by XML parsers, while PCDATA will be
checked for syntax errors
what XML processing model reads the entire XML document into the memory?
DOM (Document Object Model)
what .Net class contains the method to obtain the root element of an XML
document?
XMLDocument class
what .Net class contains the method called WriteElementString?
XMLTextWriter class
a Document Type Definition file...
is used to define the structure of an XML file
,what does the following line of code in a DTD file mean?
Code:
<!ELEMENT instructor(name, course+, officeHours*, phone | email)
the XML instance file must have an element <course>
why do we need to invent XML Schema after DTD has been invented?
DTD does not follow XML syntax
what is the purpose of defining a default namespace in an XML file?
to reduce the number of namespace qualifiers prefixed to the element names
what type of file does the following piece of code most likely belong to?
Code:
<Book>
<Title>name of book</Title>
<Author>name of author</Author>
<Year>year</Year>
<ISBN>1234</ISBN>
</Book>
XML instance file
an attribute with an element...
is never implicitly qualified by the qualifier of the element
the Extensible Stylesheet Language Transformations (XSLT) can be used to
transform an XML file to...
another XML file, with the same or a different structure
an HTML file
where are RSS and Atom feeds currently used? Select all that apply.
input and output RESTful services
what are the new features implemented in Atom? Select all that apply.
- allow autoupdate
- allow autodiscovery
,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.
how are the special markup characters presented in XML files? what are CDATA
and PCDATA? what are their differences? what is the difference between entity
reference and CDATA?
special markup characters are presented as an entity reference or a character reference
to differentiate them.
CDATA is data that appears between a pair of special tags "<![CDATA[" and "]]>"
PCDATA is any data that are not in CDATA tags.
They are used to handle the appearances of reserved characters.
what is an XML namespace? why is it useful? how is a namespace defined?
a namespace is declared as an attribute of an element. it binds a prefix name (qualifier)
to a schema definition and then uses that prefix whenever required. Its used to limit the
scope of a name of a DTD or schema to eliminate conflict.
what are DOM, SAX, and XPath models? list their strengths and weaknesses.
what .Net FCL classes and methods exist for reading and writing XML files?
DOM: reads an entire document into memory for random access. Its a problem if the
XML document is large, which takes up a lot of memory. It represents a document as a
rooted tree of nodes.
SAX: simply used for reading XML contents and is less focused on the structure. Its
streamed based and has a forward-only and read-only API to XML documents. You can
read line by line until you find what you're looking for.
, XPath: a language for accessing parts of an XML document in a way that a file system
accesses its files using a path. We can identify certain nodes within a document as well
as attributes. You can not write in XPath.
filestream and XML classes
compare and contrast XML DTD and XML XSD. what .Net FCL classes and
methods exist for validating XML files?
XSD is a more powerful alternative to DTD that defines the structure and types of an
XML document.
DTD is not XML-based which required separate tools to process DTD documents,
whereas XSD is XML-based.
XSD is extendable and reusable.
DTD is limited to only string type, whereas XSD supports basic types and can define
other complex types.
XMLReader and its .Create(...) method can be used to perform validation, supporting
both DTD and XSD files
compare and contrast RSS and Atom feeds. what are their similarities and
differences. where are they being used?
most noncontainer elements of RSS are string types, whereas Atom's noncontainer
elements allow more flexibility in associating with different types of data.
Atom has automated features like autoupdate that automatically adds timestamp when
a feed is changed, and autodiscovery is for clients who know the URI of a web page to
find the location of that page's associated Atom feed automatically.
both are used for describing/representing feed data and are used in RESTful services.
