DocumentBuilderFactory
To create an XML document using XmlTexWriter class, you need to open a file
stream and then create an XmlTexWriter object:
fS = new FileStream(fLocation, FileMode.CreateNew); XmlTextWriter writer = new
XmlTextWriter(fS, System.Text.Encoding.Unicode);
What operations need to be performed in order to properly close the files?
fS.Close(), writer.Close()
Answer the following questions.

the XML file "Course.xml"? No(2) What line of code (see the numbers right to the
code) reads a new node into the memory? Line 3(3) What does the method
"reader.MoveToNextAttribute()" at line 7 return, if the node has no more attribute?

What is the capacity (expressivity) of XSL as a programming language? Select all
that apply.
It is able to express conditions using if-then-else constructs.
It is able to express loops.
It is Turing complete and thus is able to express general computing.

another XML file, with the same or a different structure.
Assume we have five (5) different Web data structures. We choose one structure
as the intermediate structure and we translate all other structures to and from
this structure. How many converters we need to have?
8 (We choose one from the 5 data structures. We design adapters to translate data from
the 4 structures and to the 4 structures. 4+4 = 8)
Assume we have five (5) different Web data structures, and we want to be able to
translate each structure directly to other four (4) structures. How many
converters we need to have?
