Dr. Cadaver: "See this <node>? It's the heart of our XML cadaver. Scalpel, please."
Dr. Cadaver: "To do this, we would write an XQuery expression like this: `xquery version="1.0"; declare variable $author count//book/author as xs:integer; let $book-count := count(//book return <authors> { for $author in distinct-values//book/author let $book-count-per-author := count//book(author=$author) where $book-count-per-author > 3 return <author><name> {concat$author,' '} </author><authors> ` This expression uses the `count` function to count the number of books and authors, the `distinct-values` function to remove duplicates, and the `for` loop to iterate over the authors. The resulting XML would contain only the authors who have written more than three books.
Dr. Cadaver: "XQuery is incredibly powerful and flexible. It allows you to perform complex searches and retrieve exactly the data you need, making it an essential tool in any web developer's toolkit."
Dr. Cadaver: "Well, Violet, I must say, you have quite the aptitude for learning these new technologies. Keep up the good work."
Dr. Cadaver: "Remember, practice makes perfect. Why don't you try applying XSLT and XQuery to your own project? You could create some truly impressive results."
Dr. Cadaver: "And don't forget to share your progress with me. I'd love to see what you're capable of."
Dr. Cadaver: returns to his lab, continues studying new techniques and best practices in using XSLT and XQuery
He made a program using XSLT and XQuery to display some data in a nice way.
Dr. Cadaver: takes a break from his research and reviews Kurisucher's progress Dr. Cadaver: "Ah, Kurisucher, it's good to see you! How are you doing today?"
Dr. Cadaver: "What brings you here today?"
Well I was wondering if you can help me with this...it seems that my code isn't working properly.
Dr. Cadaver: "Of course, Kurisucher. Let's take a look at your code." puts on his glasses and leans forward
Okay. Shows his screen with the XSLT and XQuery code he made.
Dr. Cadaver: "Hmm, interesting. Let's see... Ah, here we go. It looks like there's a small mistake in your XSLT template. Try changing that line..." points to a specific line of code
I'll change it. He changed it
Dr. Cadaver: "Hmm, that should do it. Let me take another look..."
Eh..I messed up the indentations. He fixes the indentations of the code
Dr. Cadaver: "There we go, that should fix it. Now let's run the XSLT transformation and see the results. Ah, that looks much better. Nice work, Kurisucher!"
Dr. Cadaver: "You know, I've been thinking about creating a training manual for XSLT and XQuery. It would be a great way to help others master these powerful technologies."
Dr. Cadaver: "I think so too. I'll start outlining the chapters and putting together some sample exercises. If you're interested, you can help me test the manual and provide feedback."
