Setup

If you haven't done this previously:

Create a new directory ~/public_html/cs312/labs for your lab exercises and set the permissions so that it the web server (anyone) can access it (chmod 755 ~/public_html/cs312/labs).

Create a new directory ~/public_html/cs312/labs/xml/ for today's exercises. Don't forget to set the permissions on the new directory (chmod 755 ~/public_html/cs312/labs/xml/).

Submission

As you complete each lab exercise, let me know and I'll come check it out.

Debugging

  • Firefox: Tools > Error Console
  • Chrome: View > Developer > JavaScript Console

Lab Exercises

1) Editing an XML file

Download the file books.xml to ~/public_html/cs312/labs/xml/.

Set the permissions on the file to 644.

Using a text editor, add entries for the following books to the XML file:

 scientists, analysts, statisticians, and more. 

 bk113

After adding the entries, check your work by copy/pasting the contents of the file into the XML validator.

2) XML Display

Write XHTML and JavaScript code to display a table with the author, title, genre, and price fields of all items in the XML file.

Hint: See the plant-table.html example from the XML lecture (starting at slide 45).
