Homework 6
Task
- Create three XQuery scripts that extract three different data from a single large XML File.
- You are expected to use at least simple FLWR expressions like the following one:
<result>
{ for $t in
fn:doc("http://tecfa.unige.ch/guides/xml/examples/shakespeare.1.10.xml/hamlet.xml")//ACT//SCENE/TITLE
return $t }
</result>
- You will get a better grade if you render in HTML, e.g.
xquery version "1.0";
let $source_doc := fn:doc("http://tecfa.unige.ch/guides/xml/examples/shakespeare.1.10.xml/hamlet.xml")
return
<html>
<head> <title>Questionnaire Items</title> </head>
<body>
Acts of Hamlet
<ol>
{ for $t in $source_doc//ACT//SCENE/TITLE
return
<li> {$t/text()} </li>
}
</ol>
</body>
</html>
... you will get an A if your are somewhat original and/or if you produce more complex queries.
Submission Dates
