FLWOR is an acronym which stands for "For, Let, Where, Order by, Return".
XQuery FLWOR Example
Let's take an XML document having the information on the collection of courses. We will use a FLWOR expression to retrieve the titles of those courses which fees are greater than 2000.
Let's take the Xquery document named "courses.xqy" that contains the query expression to be executed on the above XML document.
Create a Java based XQuery executor program to read the courses.xqy, passes it to the XQuery expression processor, and executes the expression. After that the result will be displayed.
Execute XQuery against XML
Put the above three files to a same location. We put them on desktop in a folder name XQuery3. Compile XQueryTester.java using console. You must have JDK 1.5 or later installed on your computer and classpaths are configured.
