Hi Marco -
Are you missing a separator ('\') in your $output variable, or in your
`fn:concat($output, '\', 'marco.xml')`?
Here's a similar example that's working for me:
```
declare variable $data := (1, 2, 3, 4);
declare variable $output := '/home/bridger/';
declare function local:process-data(
$seq as item()*
) as item()* {
<test created="{fn:current-dateTime()}">
{
for $s in $data
return(
<item>{$s}</item>
)
}
</test>
};
let $filename := "bridger.xml"
return
file:write($output || $filename, local:process-data($data))
```
I hope this is helpful!
Best,
Bridger
