,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.
