As a follow-up to this thread I have discovered an undocumented
function call that will create a file system directory:
xdmp:filesystem-directory-create($directory)
This function is used within the Admin code that is shipped with
MarkLogic. Not sure why it isn't documented as it seems to work
very well. It will not automatically create parent directories, so
it is necessary to first create the parent, then the subdirectory.
The code below shows a simple sample. The try/catch is used for the
case where a parent directory might already exist and we want to
continue to create the subdirectories.
xquery version "1.0-ml";
(: Must create parent directory first :)
for $dir in ("C:/tmp/a", "C:/tmp/a/b", "C:/tmp/a/b/c")
return
try {
xdmp:filesystem-directory-create($dir)
}
catch($e) {()}

For those that are interested, a directory can be created by using
MLJAM to make a call out to Java to do the directory creation. You
will need to setup MLJAM (see http://developer.marklogic.com/howto/tutorials/2006-05-mljam.xqy)
The code below can then be used to do the directory creation.
(Obviously you will need to change it to match your environment)
David
xquery version "0.9-ml"
module "http://mySite.createDir";
declare namespace dir = "http://mySite.createDir";
import module namespace jam = "http://xqdev.com/jam"; at "/modules/
jam.xqy"
define function createDirectory($directory) {
jam:start("http://localhost:8080/mljam/mljam";, "mljam",
"secret"),
jam:set("newDirectory", $directory),
jam:eval('
import java.io.*;
// Create one directory
boolean success = (new File(newDirectory)).mkdir();
if (success) {
System.out.println("Directory: " + newDirectory + "
created");
}
'),
jam:get("success"),
jam:end()
}

Not directly, no. Depending on what you're doing, you might want to
look
into XQSync
(http://developer.marklogic.com/howto/tutorials/2006-08-xqsync.xqy).
Another possibility is to write a simple web service, in a language of
your choice, that performs the directory-create on demand. Your XQuery
could POST a directory name to it, using xdmp:http-post().

Thanks - that clarifies why I'm not seeing any directories created
on the file system.
What I really want to do is the ability to create a directory in
the file system so that I can write a file to it with xdmp:save()
xdmp:save() works very well as long as the directory already exists
- hence the need to create the directory before performing the save
operation.
It looks like xdmp:filesystem-directory will only give a listing of
files within an already existing directory. (not create one)
Is there a function to create a directory on the file system?
Thanks
David

xdmp:directory-create() creates a directory in the current
database. It
may be that
http://developer.marklogic.com/pubs/4.0/apidocs/UpdateBuiltins.html#xdmp
:directory-create
isn't clear enough about this.
Perhaps you want
http://developer.marklogic.com/pubs/4.0/apidocs/AdminBuiltins.html#xdmp
:filesystem-directory
instead?

This is on WindowsXP with ML version 4.0-1
Am I doing something wrong, or is this functionality broken? It
appears that both relative and absolute paths do not work.
Thanks,
David
