[MarkLogic Dev General] Preserving namespaces when copying documents between databases

Hello!

Is there a reliable way to copy a document from one database to another without losing namespace information? I have tried using xdmp:save and performing a backup and restore of the forest, but neither method reliably preserved the namespaces of all document elements.

Thank you.

[MarkLogic Dev General] cqsh question

Using the cqsh tool, is it possible to load a local file using
xdmp:document-load() within a query, or is the only loading
functionality that supplied by the "load" command or
"cqsh --load file"?

The built-in cqsh load command doesn't provide for passing options in
the way that xdmp:document-load() does.

Re: [MarkLogic Dev General] cqsh question

You can use xdmp:document-load() with cqsh but the file would have to be
located on the server. The only option currently supported in cqsh for
loading local files is passing in a uri.

  cqsh --load -n '/my/doc/uri' /tmp/localfile.xml

or you can give a uri prefix for loading multiple files:

  cqsh --load -i '/docs/' /tmp/*.xml

cqsh is still using the old XDBC libraries under the covers. I'm hoping to
update cqsh to use XCC which has a much better interface for document
loading. What options would you like to see added to cqsh load?

[MarkLogic Dev General] Application (and session) variables???

Is there such thing as an application level variable in MLS?  Something 
that can be created when MLS starts and is resident in memory all the 
time?  I've looked around the documentation and can't anything, am I'm 
missing something?

On a side note, I've been using session variables in lieu of application 
variables and found some inaccuracies in the documentation for 
xdmp:get-sesssion-field() function...  The documentation says it returns 
a xs:string, but I believe it returns an item().  When I store an 
element() with xdmp:set-session-field(), I get an element() from 
xdmp:get-session-field().  It would also be nice if the default (2nd) 
parameter of xdmp:get-session-field() would take an item rather than an 
xs:string.

Thanks

Wyatt

RE: [MarkLogic Dev General] Application (and session) variables???

Hi Wyatt,

MarkLogic has no concept of what you describe as an application level
variable.  Depending upon what you want to use it for, you could of
course achieve this by storing the information in a document in the
database--then it would always be accessible to applications.

You are indeed correct that the return type of xdmp:get-session-field is
an item()*, nos a string as the doc says.  Also, it would make sense for
the second parameter to take an item()* since that is what it returns.
Thanks for pointing those things out, and I'll take them up with
engineering.

Thanks,
-Danny

With our current use case, the "permissions" and "collections" options,
but the ideal would be access to everything that xdmp:document-load()
allows.

Thanks for the work on cqsh--it's a handy tool for a lot of things.

Re: [MarkLogic Dev General] Application (and session) variables???

As it happens, a request for enhancement was submitted yesterday after
discussion over how one might store XML fragments on a per-session
basis.

[MarkLogic Dev General] sorting efficiency question

hello all. i need to do a 3-level sort, somewhat as follows:

let $docs := for $i in fn:distinct-values($results//titleName),
                  $j in fn:distinct-values($results//titleTypeName),
                   $k in fn:distinct-values($results//titlePhotoSequenceNumber)
             let $p := $results[//titleName = $i and
                                //titleTypeName = $j and
                                //titlePhotoSequenceNumber = $k]
             order by $i, $j, $k
             return $p

the above works, and is easy enough to write, but it's not terribly
speedy at returning results. does someone have, or can someone
suggest, a better approach? 

thanks.

Re: [MarkLogic Dev General] cqsh question

I've released a new version of cqsh (0.5.0) which supports a few new load
options: --permission, --collection, --quality, and --type. I also
re-factored the code to use the latest XCC java libraries. I haven't done
much testing so let me know if things break.

You can download here:
  http://xqzone.marklogic.com/svn/cqsh/releases/cqsh-0.5.0-bin.zip

Example load options:

 cqsh -l -n /myuri.xml -c mycollection -x read:admin -t xml -q 20 /file.xml

[MarkLogic Dev General] Content-Type, xdmp:get-request-field() and xdmp:get-request-body()

I'm running into a problem using xdmp:get-request-field() with POST 
requests...

According to the xdmp:get-request-body() documentation:
"If the content-type of the POST body is 
application/x-www-form-urlencoded, it is not available here, but instead 
is available in its decoded form through xdmp:get-request-field-names() 
and xdmp:get-request-field()."

I've trying to upgrade to the latest (1.5.0_rc2) Prototype Framework 
(http://prototype.conio.net), and they now add a charset parameter to 
the Content-Type header field...

     application/x-www-form-urlencoded; charset=UTF-8

This changes how MLS interprets the Content-Type and the data is only 
available via xdmp:get-request-body().  I'd much rather MLS know that 
this if form data, parse it, and make it available via 
xdmp:get-request-field().  This means no changes to my XQuery code.

My question is whether this is a short-coming of MLS that is likely to 
change, in which case I can hack the Javascript and leave my XQueries 
alone, or if this is intentional and I should update my XQueries to use 
xdmp:get-request-body() and parse the body data?

Thanks to anyone with guidance on this issue.

Wyatt
