Answers

1.  

Exercise 1 solution

e. None of the above. All tags are correct and there are no missing tag delimiters.

2.  

Exercise 2 solution

There are two errors in the XML document. The first error is that the first line, containing the <xml> tag, should look like this:

   <?xml version="1.0" ?>   

The second error is that the closing </customer> tag is missing from the end of the second customer entry. XML strictly enforces the tag (element) hierarchy.

3.  

Exercise 3 solution

Its an XML data island, embedding an XML data/metadata page directly into an HTML web page script.

4.  

Exercise 4 solution

e. None of the above. XSL is a formatting language that allows application of templates to consistent data repetitions in XML documents. That means that for tags that are duplicated in an XML document, their content can be displayed consistently, when one or more repetitions are displayed in a web page.
