Hi, I am a newbie to XQuery processor. I was able to run the following Xquery from
the command line by running java net.sf.saxon.Query line. query version
"1.0"; declare copy-namespaces preserve,inherit; for $b in
doc("d:/saxon/Emp.xml")//Company/Employee for $d in
doc("d://saxon/Dept.xml")//Comp/Department where $b/Dept = $d /DeptId
and $b/Dept = "D1" return <Emp> <Name>
{$b/EmpName} </Name> <DeptName> {$d/DeptName}
</DeptName> </Emp> ************************** I would like
to translate the above FLOWR expression so that it could be called from within my java
program. Which specific Xquery functions should I use ? I went thru' the documentation
but it has sample code only for basic Xquery expressions.. I would greatly appreciate if
someone could upload a sample code containing FLOWR expressions. Thanks, Anu

Firstly, I'm surprised that doc("d:/saxon/Emp.xml") worked. The
argument to doc() is required to be a URI, not a filename. You should write
doc(file:///d:/saxon/Emp.xml"). Secondly, the API for running queries is the
same regardless how complex the query is. You haven't said what you did, or how it
failed, so it's impossible to tell what you did wrong. I can't give you any advice
beyond referring you to the documentation at
http://www.saxonica.com/documentation/using-xquery/embedding.html If you can't get it to
work, please show us your code and tell us how it was failing. Michael Kay
