[Exist-open] Error loading an XML file using XQuery in the sandbox

[Mattio V. <mat...@gm...>]

Hello,

I just downloaded and installed eXist and I'm trying to load some XML
files.  Since I'll be loading the documents via code if I use the
system, I was trying to write XQuery for loading in the sandbox.
Unfortunately I keep getting the same error.

The XQuery I'm trying to run is:

declare namespace xmldb="http://exist-db.org/xquery/xmldb";

let $load-status := xmldb:store("test", "test.xml", "C:\test.xml")
return <load-status> { $load-status } </load-status>

The XML file is:

<?xml version="1.0" encoding="utf-8"?>
<root>
	<p>Sample paragraph.</p>
</root>

The error message I'm getting is:

Error while evaluating expression: declare namespace
xmldb="http://exist-db.org/xquery/xmldb"; let $load-status :=
xmldb:store("test", "test.xml", "C:\test.xml") return  { $load-status
} . XMLDB reported an exception while storing
documentorg.xmldb.api.base.XMLDBException: fatal error at (1,1) :
Content is not allowed in prolog. [at line 120, column 21] In call to
function: sandbox:exec-query(xs:string) [134:10]

I found a couple of eXist emails about this error relating to BOM, but
they're several years old.

Any suggestions or pointers?

Thanks!
