How can I get at the document url?

What would be the right way to get at the document url of the xforms
document? I only find fn:document-uri(), but can I get at the xforms
document with xpath, or only at instances defined in the model?

Do I need to escape into javascript for this?

Thanks for any pointers,

Mathias

When you say JavaScript, I suppose you mean to get at document
using it. Orbeon provides a way for you to get values of
controls and dispatch events:

http://wiki.orbeon.com/forms/doc/developer-guide/xforms-
extensions#TOC-JavaScript-Integration

It is not difficult to pass an instance to javascript by
converting the xml to text and holding it in a (hidden) input
control. I use xxforms:serialize as html, I recall it creates
line breaks that make parsing it in JavaScript better. Roughly:

<xforms:bind nodeset="text" type="xs:string"
calculate="xxforms:serialize( instance('my-instance'), 'html' )"/>

...

var xml = GXml.parse(text); // Google Map API to parse xml

I don't know that you can get the xforms document in JavaScript,
and indeed, the "real" document is on the server, where the full
XPath 2.0, etc., environment is assured.

Hope I understood your question,
Hank

Do you mean the URL of the document on the server, e.g.:

oxf:/apps/my-app/foo.xhtml

Or do you mean the URL as seen by the browser, e.g.:

http://example.com/orbeon/my-app/foo

I mean the url the browser sees, including query string.

I know how to get instance data into xforms with orbeon, e.g. XInclude /
input:instance , but what would be a more portable way? If I could get
the document url (ok, browser document url) I could use the query string
and load an instance using a dynamic submission element.

I'm just curious, I have a solution for now.

I see. You can get known parameter values with the extended
functions, e.g.:

<xforms:setvalue ref="my-param" value="xxforms:get-request-parameter('myparam')"/>

http://www.orbeon.com/ops/doc/reference-xforms-functions

To get the url, you can use the request generator processor

http://www.orbeon.com/ops/doc/processors-generators-request

in an xpl file with an output param. And the file is the
model attribute of your page flow. Then, e.g.:

<xforms:instance src="input:data"/>

(If I have it right this time)

Cheers,
Hank

Ja, that's what I'm doing right now.

:-) Thanks for still thinking about it.

I was looking for something not orbeon-specific, but included in xforms,
but maybe there is no such thing.

Cheers, Mathias

PS:

I thought with xforms 1.1 I could do something like

<submission replace="instance" instance="instanceToBeEdited">
<resource
value="concat(instance('conf')/path/to/data, string-after(document-uri(/), '?'))"/>
</submission>

and trigger it at xforms-ready. (The "parsing" here obviously sketchy, and it's not tested
and I'm not yet fluent in xforms so the example is probably faulty, but I hope good
enough to show what I thought could work.)

I will test it in a few days, but I hoped I could get an obvious
solution on this list, freeing me from experimenting.

PPS: searching for a solution I found
http://www.ibm.com/developerworks/xml/library/x-xformsdynamic/index.html
which is a javascript way to do it in xforms 1.0. I still hope for
something within xforms.

Mathias,

I think what we need is to add some extension XPath functions. We
already have some to get request parameters, headers, etc.

http://www.orbeon.com/ops/doc/reference-xforms-functions#orbeon-extensions

Basically, we need to complete that API. It would be an easy thing for
a contributor to do based on existing functions! See:

http://github.com/orbeon/orbeon-forms/tree/master/src/java/org/orbeon/oxf/xforms/function/xxforms/
