xslt processor in xpl action

Hi,

I have problem with using xslt processor in the xpl file.

At first I definied simply xml, xsd and xslt file (transform.xsl).
After this I attached xslt processor in the load-xml.xpl file.

At the xform document I have two input fields
and one upload control, which is connected to the load xml action.

load-xml.xpl
--------------
[...]

<p:processor name="oxf:request">
    <p:input name="config">
        <config>
                <include>/request/container-type</include>
        </config>
    </p:input>
    <p:output name="data" id="container-type"/>
</p:processor>

<p:processor name="oxf:pipeline">
    <p:input name="config" href="read-uri.xpl"/>
        <p:input name="uri" href="aggregate('uri', #instance#xpointer(string(/files/file[. != ''][1])))"/>

            </cache-control>
        </config>
       </p:input> 
</p:processor>

I fired upload action and I had an error in the log:

I tried to add some additional namespaces, but I always have this error.
I searched at the ops forum, studied examples of xforms, xpl pages
but I haven't found any solution.

My xslt file is correct, but only without xslt processor everything works fine.
In other application I used xslt transformation in page-flow file and it was working correctly.

I attached my all files in a zip archive.
File to upload: toUpload.xml

I tested it in Orbeon 3.6 and 3.7 beta1.

Thank you in advance,
Marcin.

In test1.xhtml, try adding the xmlns:xs declaration to the <xf:bind ../>
node at line 28 (yes, I know it is also declared for the whole document!)

It could be that in the <xf:model ... > you need namespace declarations
local to the model (as if it is an independent XML document).

Thank you for your replay.

I tried to modify line 28 like this:
<xf:bind id="file" nodeset="file" type="xs:anyURI" <b>xmlns:xs="http://www.w3.org/2001/XMLSchema"/>

But I have the same error.

i'm no xstl expert, but the error occurs when the xslt transformation is
executed - so you maybe have to add a namespace for xs to the xsl
stylesheet, too.

I added a namespace for xs to the xsl stylesheet and ... to the all files in the project.
I have the same error.

As I said I checked this transformation in other application and it was working correctly.

I found the problem with the same error name:
http://www.nabble.com/Undeclared-prefix-in-xsi%3Atype%3A-xs-to13564818.html#a13564818

Maybe this is a bug ...

Yes, sounds like a bug.

Try adding a dummy xs:something element in your model somewhere - maybe that
will get the namespace prefix declaration to propagate, from reading the bug
report URL you posted it sounds like that could be the source of the
problem...  Maybe because the only usage of xs: is within an attribute
value, something somewhere is dropping the namespace declaration.

I added this code:

<xf:model id="model" schema="/apps/test/test.xsd">
    [...]
   <xf:bind id="b-boolean" nodeset="ts:Client/ts:Choice" type="xs:boolean"/>
    [...]
</xf:model>

<body>
  [...]
  <xf:input id="i-boolean" ref="ts:Client/ts:Choice"/>       
  [...]
</body>
                       
and modify all other files (xml, xsd)
Unluckily I have the same error.

Hmm... maybe my method of using xslt in the xpl file is wrong ?

I attached my all files in a zip archive.

Hi,

Any ideas how can I use xslt in the xpl file (with upload action) ?

Otherwise maybe this problem should be reported as a bug.  

Regards,
Marcin

Hi Marcin

Looking at your files again, the error could be a red-herring.

A couple of points:

1) in your read-uri.xpl pipeline, you are forcing the content type to
application/octet-stream, but I presume your uploaded file is an XML
document?

This will result in the XML document being encapsulated in a <document>
node, as a binary document, see
http://www.orbeon.com/ops/doc/reference-formats for information on this

2) you are using oxf:http-serializer to serialise the output - this
processor expects input encoded in the <document> format as well - so you
need to take your output of the xslt, and use eg an oxf:xml-converter to
convert the xml output to a format suitable for serializing - see
http://www.orbeon.com/ops/doc/processors-converters for info

Regards
Steve

Hi Steve,

It works well now.
Thank you for all Your help!
