Hi

I generated and ecore with and xsd. I'm trying to read an xmi of that model with Epsilon ETL, I want to do a model to model transformation, the xmi code is

XMI example:
<select>
<![CDATA[my data]]> </select>

XSD section:
<xs:element name='select'>
<xs:complexType mixed='true'>
<xs:attribute name='canParse' default='yes'>
<xs:simpleType>
<xs:restriction base='xs:string'>
<xs:enumeration value='yes'/>
<xs:enumeration value='no'/>
</xs:restriction>
</xs:simpleType>
</xs:attribute>
<xs:attribute name='externalQueryFile' type='xs:string' use='optional'/>
</xs:complexType>
</xs:element>

I don´t know how to read that in ETL.

Thanks!

Hi Oscar,

Have you generated code from your Ecore/XSD or are you trying to load the XMI model reflectively? (i.e. are the Ecore/XSD and XMI files located in the same Eclipse workspace?)

Cheers,
Dimitris

Hi Dimitris

I have generated an ecore from an xsd, the problem is when I try make a transformation model to model.

rule MyTransform
transform
root : Reports!DocumentRoot //see attachment MM
to
dest : SomeMM!Class{
var report = root.report.first();
var select = report.data.first().dataSource.first().select;

dest.attr = select.cdata; // I just don´t know how to read cdata info here

}

My XMI (in):

<?xml version="1.0" encoding="ASCII"?>
<Reports:DocumentRoot xmi:version="2.0" >
<report beforeReportTrigger="beforereport" dTDVersion="9.0.2.0.10" name="Admrmenu">
<data>
<dataSource name="ds">
<select>
<![CDATA[My cdata info here]]> </select>
</dataSource>
</data>
</report>
</Reports:DocumentRoot>

With Exeed I can add CDATA to xmi.

Thanks!

Hi Oscar,

I'm not sure that the EMF parser reads this bit of CDATA (select.mixed returns an empty collection).

Cheers,
Dimitris

Hi,

I think this issue is related with something I have asked about before regarding FeatureMaps (message #1517409) and from what I recall CDATA are supposed to be read as FeatureMaps. From an XML perspective I think it makes sense that a CDATA field is a key/value pair.
