Readers,
According to the xquery specification , the flwor expression (§ 3.8)
syntax has optional parts, i.e. the 'let' part of the clause.
Therefore the following expression was saved as an 'xq' file:
<html>
<body>
<ul>
for $x in fn:doc("xmldatabasefile.xml")/bookstore/book/author
order by $x/author
return $x/author
</ul>
</body>
</html>
This xquery file was processed using jedit xml plug-ins; xml file:
<?xml version="1.0" encoding="utf-8"?>
<!-- Edited by XMLSpy®, taken from http://www.w3schools.com-->
<?xml-stylesheet type='text/xsl" href="xstylesheetexample.xslt" ?>
<bookstore>
<book
category="COOKING">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year>2005</year>
<price>30.00</price>
</book>
...
The output was:
<html>
<body>
<ul>
for $x in fn:doc("xmldatabasefile.xml")/bookstore/book/author
order by $x/author
return $x/author
</ul>
</body>
</html>
The expected output was a list of authors within the html un-ordered
list element. What is my mistake please?
