[EMF] parse enum values surrounded by whitespace [message #1842705]

Hi,

I created a genmodel (and ecore model) from an existing xml schema definition. The model contains a couple of enumerations. Then I generate an implementation and try to read some of the models I have (using the xmi serialization). These models are manually created. When parsing a list of enumeration values, some users have written:

   <SupportedFormats>
      <elt>SUPPORTED_REPORT_FORMAT_TYPE_XML</elt>
   </SupportedFormats>

Others have written:

   <SupportedFormats>
      <elt>
         SUPPORTED_REPORT_FORMAT_TYPE_XML
      </elt>
   </SupportedFormats>

The implementation I generated, does not succesfully parse the second example as it tries to lookup an enumeration value that includes the newlines after <elt> and before </elt>.

Is there a way to configure the xmi parser such that it 'trims' whitespace of enumeration before trying to match them agains the set of allowed values?

Regards,
Wilbert

You'll need to specialize the implementation of the generated XyzFactoryImpl.createAbcFromString method to trim whitespace before looking up the enumerator.

Hi Ed,

You just beat me to it.

The genmodel properties for an enumeration containa 'Convert-to-string Body' and a 'Create-from-string Body'. Copying the generated code of another enumeration and inserting the trim() operation in the Create-from-string Body did the trick indeed.

Thanks!

Regards,
Wilbert.
