Re: AW: Stylesheet for Transforming HTML forms to XForms

Hi Roman,

Again really good work, this is fun :)

I have some comments about the transformations:

1) in application_from.xhtml you make a xsi:type="xs:email". Two 
problems: xs is not a defined prefix so I cannot see what the type it is 
intended to be (a schema datatype or a xforms datatype). The other 
problem is that there is no xs:email datatype define in XML Schema 1.0 
or in XForms 1.0. However I like the idea of assign such a datatype (and 
indeed there is one in XForms 1.1) so maybe you can link you own schema 
and assign the datatype from that (you can just copy the definition from 
XForms 1.1).

2) It may be my mistake but instance('formData1')/ should be without the 
trailing / e.g. just instance('formData1')

3) You might know it since checkbox.xhtml does not transform probably 
but the transformation of a checkbox should be:
<xforms:select1 ref="zutat" appearance="full">
  <xforms:label></xforms:label>
  <xforms:item>
    <xforms:label>Salami</xforms:label>
    <xforms:value>salami</xforms:value>
  </xforms:item>
  ....
</xforms:select1>

4) in file_input.xml. This is the same as for 1) the xs prefix has to be 
declared. Another thing you could do was to include a mediatype and a 
filename element under the upload element and bind they values to 
attributes on the upload instance node. E.g. making the upload look like:
<xforms:upload mediatype="text/*" style="width: 240px" ref="file">
  <xforms:label></xforms:label>
  <xforms:mediatype ref="@mediatpype"/>
  <xforms:filename ref="@filename"/>
</xforms:upload>

and in the instance
<file mediatype="" filename="" xsi:type="xs:base64Binary"/>

5) In multiple_forms.xhtml there is a problem which is entirely my fault 
because I was fuzzy in my first mail. You should namespace the 
transformed xhtml:form -> xforms:group with a model attribute. E.g. the 
transformed <xhtml:form> should look like
<xforms:group ref="instance('formData1')" model="model1"/> and for the next
<xforms:group ref="instance('formData2')" model="model2"/>
Sorry about that. The current version will not work since you are not 
allow to cross reference instance between models in XForms.

6) Very nice transformation in outgroup.xhtml. There is a choices 
element in XForms which will allow you to transforms <optgroup 
label="Names starting with B"> into
<xforms:choices>
  <xforms:label>Names starting with B</xforms:label>
  <xforms:item>
    <xforms:label>Berta</xforms:label>
    <xforms:value>Berta</xforms:value>
  </xforms:item>
  ...
</xforms:choices>

7) For select.xhtml I like Tom Waits ;)

8) I really like the reset trigger. It is a good detail.

Keep up the good work!

Best regards,
David
