[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!

Normally, this error represents an actual problem in the document that 
is being parsed. So either a different document is parsed than expected 
or... the document is 'dirty'. Do you you have an editor around to view 
the document? Or byte editor?

I had problems with Ultra-edit for quite some time....

Thanks for the quick response, Dannes.

I have UltraEdit, but I'll find another hex editor to see what's going
on.  In the meantime, I found one of the samples and tried loading it
but the same error appears.

I ran:

declare namespace xmldb="http://exist-db.org/xquery/xmldb";
xmldb:store("test", "test.xml", "C:\Program
Files\eXist\samples\shakespeare\hamlet.xml")

And the error was:

Error while evaluating expression: declare namespace
xmldb="http://exist-db.org/xquery/xmldb"; xmldb:store("test",
"test.xml", "C:\Program Files\eXist\samples\shakespeare\hamlet.xml") .
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 tried running this in Firefox and Chrome with the same response.
I'm on Windows XP Pro, if that helps.

xmldb:store looks at the type of the 3rd argument: if you pass a string, 
the function believes it should parse that string into XML and store it. 
You thus get a parsing error because "C:\Program..." is not valid XML.

You have to make sure that the 3rd argument is recognized as an URI:

xmldb:store("test", "test.xml", xs:anyURI(".../shakespeare/hamlet.xml"))

Thanks Wolfgang.

That cleared up the error, but the document didn't load with that
approach.  From where is the path relative from?  I tried to use C:\
since I'm on a Windows machine, but it threw and invalid URI error.

When I used "/samples/mattio/sample.xml" or
"../samples/mattio/sample.xml" nothing loaded and no error was thrown.

On the other hand, when I switched to use
xmldb:store-files-from-pattern($collection, "C:\Program
Files\eXist\samples\mattio", "*.xml") the document did load fine.

sure, C:\ cannot be a URI, there should be a foreward slash ;
file:///C:/path/doc.xml should work ?

cheers
