xsltforms-support — XSLTForms support list

[Xsltforms-support] Is it possible to generate an xhtml with php, based on xsltforms?

[Lorenzo De T. <lor...@gm...>]

Is it possible to generate an xhtml document with an xform with php, based
on xsltforms?
  $xsl->importStyleSheet($doc);
  $doc->load($xml_filename);
  echo $xsl->transformToXML($doc);

I have tried, but it seems it needs the <?xml-stylesheet
href="../xforms/xsltforms/xsltforms.xsl" type="text/xsl"?> line to
understand where are the xsltforms subfolders.

Thank you for your help.

Those modifications are typical differences between XForms 1.0 and 
XForms 1.1. They are not especially difficult to implement but each

"Error" treatments are not yet my priority but I agree those situations 
might also appear...

Yet another time problem... Plenty of tests have to be performed with 
all the recent browsers (help is welcome ;-) ). Before the end of 
September seems, for me, to be a possible challenge.

Thanks!

Thank you Alain, your latest patch fixes the troubles I had with case
statements.

There is still the cornercase of multiple  - selected = "true" - statements
outstanding, but this is really low prio.

What about promoting the current trunk to a new relase ?

Best Regards
Rusco.

Because inline elements are now generated instead of table elements,

[Xsltforms-support] anyURI support (XML Schema Primitive Datatype)

[Lorenzo De T. <lor...@gm...>]

Ciao from Italy,

I have written an xform that uses "anyURI" (XML Schema Primitive Datatype) <
http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/#built-in-primitive-datatypes>
but it doesn't seem supported by XSLTForms.

   <xf:bind id="photo" nodeset="/person/photo/@uri" type="xsd:anyURI" />

Firefox outputs a Javascript error: Type anyURI not defined

What about a future implementation?

Thanks for the wonderful application!

[Xsltforms-support] [Fwd: attribute namespace problem]

[Stephen C. <Ste...@ut...>]

After sleeping on this problem, the solution became obvious.

Basically the difference between the case that works (the submission) 
and the one that does not (the select1) is that the submission instance 
has been  preset with the missing namespace.

So if you do the following:

         <xf:instance id="inst_project_role_person"
        
 src="../deegree-wfs/services?service=WFS&amp;version=1.1.0&amp;request=GetFeature&amp;namespace=xmlns(aatams=http://www.imos.org.au/aatams)&amp;typename=aatams:project_role_person">
         <data xmlns="">
             <aatams:project_role_person gml:id="">
                 <aatams:person_ref>
                     <aatams:person gml:id=""/>
                 </aatams:person_ref>
            </aatams:project_role_person>
        </data>
     </xf:instance>
 
You don't seem to have a problem. This is non-standard of course but 
hey, it works.

Hello

I am getting an error in Firefox with an XPath having an predicate 
containing an attribute with a namespace.

This is the code in question:

       <xf:select1 bind="project_role_person" appearance="minimal" 
incremental="true()">
           <xf:label>Person</xf:label>
           <xf:item>
              <xf:label/>
              <xf:value/>
           </xf:item>
       <xf:itemset 
nodeset="instance('inst_project_role_person')//aatams:project_role_person[aatams:project_ref/aatams:project/@gml:id=instance('inst_prp')/project_id]">
              <xf:value ref="@gml:id"/>
          <xf:label ref="aatams:person_ref/aatams:person/aatams:name"/>
           </xf:itemset>
           <xf:help>This is a presently unhelpful help message</xf:help>
        </xf:select1>

The problem sees to be the use of @gml:id, the error I see is:

Error: XForms Error (10): Error parsing XPath expression: 
instance('inst_project_role_person')//aatams:project_role_person[aatams:project_ref/aatams:project/@gml:id=instance('inst_prp')/project_id]

Elsewhere the same use of @gml:id is not causing a problem so I suspect 
it is an issue with the select1 implementation only.

For example the code below works in my submit, which is doing exactly 
the same thing (I think).

              <xf:insert 
nodeset="instance('inst_data')//aatams:model_ref/aatams:device_model"
                         
origin="instance('inst_device_model')//aatams:device_model[@gml:id=instance('inst_subfeatures')/device_model_id]"/>

The one difference is that the select1 nodeset XPath will not find any 
nodes on loading the form as the value "instance('inst_prp')/project_id" 
has not been set by the user from another select1.

I'd really appreciate some assistance in getting this resolved as it is 
a final hurdle before my app. can be used in production.

Thanks

[Xsltforms-support] using calculated value in select1 itemset

[Stephen C. <Ste...@ut...>]

Hello,

I would like to calculate the labels appearing in select1, this might be 
possible using the xf:bind 'calculate' attribute.

However whilst the following example works, it only works if the 
caculated 'new_value' nodes are pre-existing in the instance.

My problem is that if the source of the data is an external source then 
the calculated nodes cannot be inserted prior to the calculation and so 
perhaps they should be created automatically?

Is there another way to handle this situation?

[Xsltforms-support] implementing string length constraint

[Stephen C. <Ste...@ut...>]

Hello,

Can anyone suggest a means to implement a maxLength constraint for 
XSLTforms.

Is it possible in the same way as HTML inputs to set a "size" value on 
the xform input?

I suspect not and that it should be done via a schema or a bind 
constraint but this does not seem to be supported in XSLTForms as yet.

In XML Schema this would be done via a restriction of the xsd:string type.

I guess I am wondering if it is possible to do it other than via a 
schema such as by a validation rule in a bind.

Thanks

[Xsltforms-support] enhancement request

[Stephen C. <Ste...@ut...>]

Hello,

In a select list the ability to compose a itemset label using an Xpath 
would be nice, this almost seems to work (typing an incorrect function 
name gives an error at least) but no result is presented.

For example:

            <xf:itemset nodeset="instance('inst_people')//person">
               <xf:label ref="concat('first_name',' ','second_name')"/>
               <xf:value ref="@id"/>
            </xf:itemset>

In this case the item labels are composed of each persons first and 
second names concatenated with an intervening space.

Re: [Xsltforms-support] confusion over instance() function

[COUTHURES A. <ala...@ag...>]

I forgot to say that I have recently developed a small application for 
XBRL instances editing and rendering which is, of course, using XSLTForms.

At this occasion, I designed the experimental formula extension allowing 
to enter, for example, "13+29" instead of "42" in numeric input fields.

There are not yet many users for this application... but it might be 
shown to french financial students next year !

The XForms 1.1 proposed recommendation says : "this function returns a 
node-set containing just the root element node (also called the document 
element node) of the referenced instance data" (AJAXForms was wrong 
returning the document node (/)...).

Also in the W3C proposed recommendation :

For instance data corresponding to this XML:

<xforms:instance xmlns="" id="orderform">
  <orderForm>
    <shipTo>
      <firstName>John</firstName>
    </shipTo>
  </orderForm>
</xforms:instance>

The following expression selects the |firstName| node. Note that the 
|instance| function returns an element node, effectively replacing the 
leftmost location step from the path:

ref="instance('orderform')/shipTo/firstName"

> As a matter of general interest, do you know of many people who have

Mark Logic has developed an "Application Builder" application delivered 
with Mark Logic Server 4.1. All around the world, people are downloading 
and testing XSLTForms but, because it's free, I don't know who is using 
it in production.

XForms is yet an emerging technology to be used in the promising XRX 
architecture. EMC has now its own engine named Formula but it seems that 
IBM is not working anymore on Ubiquity XForms project and I would not be 
surprised if this project is abandoned soon... XSLTForms is still the 
most mature of its kind !!

[Xsltforms-support] confusion over instance() function

[Stephen C. <Ste...@ut...>]

Hello,

I am still working away and developing my CRUD application with 
XSLForms, the only major issue so far is my forms won't work in IE 6.0. 
I think there is a javascript issue that I've not debugged as yet.

However I have a bit of confusion over the instance() function,  in 
XSLForms it returns the root node of the instance, if this is the 
specification then that is fine but  it seems a bit counter-intuitive as 
'/' and '//' have different meanings in XPath.

In the following example the first 2 'xf:output' elements work, the 
third is invalid, the fourth is valid.

<?xml version="1.0" encoding="iso-8859-1"?>

                <sample:data>abcdefg</sample:data>

            </span>
        </div>
        <xf:output value="instance('nums')/sample:item[last()]">
                    <xf:label>number <b>last</b>()</xf:label>
                </xf:output>
        <xf:output value="sum(instance('nums')/sample:item)">
            <xf:label>number <b>sum a</b></xf:label>

                </xf:output>

        <div id="console"/>
    </body>
</html>

If this is correct behaviour then the example from 
http://www.w3schools.com/xforms/xforms_functions.asp(as below) is wrong.

****
instance(string)

An XForms Model can contain more than one instance. This function 
returns the root node of the specified instance data

<xforms:instance id="orderform">
<firstName>John</firstName>
</xforms:instance>

ref="instance('orderform')/firstName"

This example returns a node-set that consists of the firstName element 
node from the instance named "orderform"

****

As a matter of general interest, do you know of many people who have 
used XSLForms in production as yet?

Thanks for your assistance.

fn:document-uri(node) is an XPath 2.0 function and its support could be 
added in XSLTForms...

You can try to define it yourself in Javascript this way :

<script type="text/javascript">//<![CDATA[

XPathCoreFunctions["fn:document-uri"]= new XPathFunction(false, 
XPathFunction.DEFAULT_NONE, false,
        function(node) {
            ...
            });

//]]></script>

Yes, this should look like this.

Orbeon is the only XForms implementation supporting XPath 2.0 and it 
would be a good idea to analyze its behavior according to the node 
parameter. Depending whether the instance is embedded or loaded 
externally, the return value should be different...

Alain,

I can't find a way to get at the document uri. Can you give me an example? 
I tried with document-uri, but that's not there. Anyway, I do not even know if 
I even think along the right lines, so I'll ask.

Is the general idea of

<xf:submission ... >
<xf:resource value=(substring-after(document-uri(instance(??), '?')) />
</xf:submission>    ^^^^^^^^^^^^^^^                       ^^ 
		    this is obviously only a first shot   Which instance??

correct?

Any hints or tips?

Thanks, Mathias

[Xsltforms-support] conditional select lists.

[Stephen C. <Ste...@ut...>]

In regards to question 2 below regarding conditional select lists, the 
attached example "test conditional selection lists" from the **"XForms 
Tutorial and Cookbook" works with XSLForms.



**-------- Original Message --------
Subject: 	Model from file reloading
Date: 	Thu, 30 Jul 2009 09:42:43 +1000
From: 	Stephen Cameron <ste...@ut...>
To: 	xsl...@li...



I am trying to generate a CRUD application using XSLForms by 
transforming a database schema document generated  by the  Apache 
DDLUtils tool. I am interested if anyone else has tried something similar.

There are a couple of things I would like to be able to do and would 
appreciate some help in knowing if they are, or could be, possible.

(1) Reloading a model based on an external resource.

This is useful if you have a select1 based on an external resource, if 
you want to add a new entry to the select list then the best way to do 
it (in my view) is to click on an "Add" button beside the select list 
and open a "New Resource XXX" page (or modal dialog), add the  new 
entry, save it, then on closing the page get the select list to update 
from the server with the new entry included. This setup handles a 
foreign-key relation in the database schema.

(2) Making a select list conditional on another select list.

Usually this situation is usually two or more linked select lists, the 
top one is initially active and the bottom 'dependant' one inactive, by 
selecting an first entry in the top list you load the list in the bottom 
one and make it active, if  you then change the entry in the top list 
you reload the bottom list with a new set of entries and remove its 
current selection.

P.S. I am more than happy to provide my XSLT stylesheets for others to 
try or improve.

Thanks.

The XForms 1.1 proposed recommendation says : "The |resource| element 
allows the URI used for a submission to be dynamically calculated based 
on instance data."

This is implemented in XSLTForms and verified according to Test 11.6.1.a 
of the W3C Test Suite.

[Xsltforms-support] how can I get the query string parameters in xforms

[Mathias P. <Mat...@gm...>]

I want to dynamically load my instance data, using something like 

http://example.com/xforms/EditorTypeA?instance=id401

I searched, but there does not seem to be an xforms way to do this, so
what would be a portable javascript way be? 

Putting the parameter value in something like a currentDocument instance
on load and then use a replacing submission using that instance value on
xforms-ready??

If that's the way, this could probably be generalized to generate a
simple xml instance from any query string
(<querystring><paramX>valueX</paramX></querystring>), does something
like that exist?

Thx for any help,

Mathias

"pre1" and "aatams" are just prefixes associated to namespaces and the 
serialized XML produced by XSLTForms is correct.

The servlet shouldn't interpret the prefixes but the namespaces : an XML 
document is to be interpreted with an XML library, even regular 
expressions can't interpret XML easily...

For human beings, it would be better if XSLTForms was reusing the same 
prefixes. This might be considered in a next version

Thanks!

[Xsltforms-support] Implementation of switch / selected="true" behaviour

[Jochen R. <j.r...@gm...>]

Hi Alain,

You probably know this already, I just send you this as a reminder that it
get's not lost in the current development roadmap:

I tested some examples of the XForms Wikibook against Mozilla-0.87-pre and
XsltForms (2 days old SVN Snapshot ) and noticed that the "switch" behaviour
is different:

Example:

<xf:*switch*>
             <xf:*case *id="1" selected="true">1</xf:case>
             <xf:*case *id="2" selected="true">2</xf:case>
             <xf:*case *id="3">3</xf:case>
</xf:*switch*>

Missing behaviour 1: If no select attribute is present, according to the
Spec the first case should be activated:

See:
http://www.w3.org/MarkUp/Forms/specs/XForms1.1/index-all-20090604.html#ui-switch-module->
Point: 9.2.2

Missing behaviour 2: If multiple selected="true" attributes are present, the
first one shall be activated.

Here the 2 real-world examples from the Wikibook:
http://en.wikibooks.org/wiki/XForms/Switch_and_Case
http://en.wikibooks.org/wiki/XForms/Show-Hide_Controls

Xsltforms Rocks !!!

[Xsltforms-support] Set time-out period for script in IE

[COUTHURES A. <ala...@ag...>]

Hello,

I've been experiencing unwanted warnings from Internet Explorer such as 
"A script on this page is causing Internet Explorer to run slowly. If it 
continues to run, your computer may become unresponsive. Do you want to 
abort the script?" due to XSLTForms processing a heavy XForms page.

Here is a link explaining that a registry key  has to be set, 5,000,000 
statements being the default value : 
http://support.microsoft.com/kb/175500/en-us/

For 10,000,000 statements, the corresponding .reg is :

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles]
"MaxScriptStatements"=dword:00989680

This is a known bug in the beta release. You can test this with the SVN
