Description Christian K.

2012-02-06 05:55:51 EST

For XML files serialized using the class ExtendedXMLSaveImpl a certain order of the XML root element attributes is established. The current order of the standard namespace and schema related attributes is:
- xmlns:xsi
- xmlns
- xsi:schemaLocation

This order does not match the order which is produced by common DOM implementations and also JDOM, e.g. Xerces uses an alphabetical order of the attributes [1].

The ordering mismatch produces undesirable side-effects if XML files are processed using other tools/parsers. This might also be done as part of automated testing where test files are processed using DOM/JDOM and text comparison is used for assertations.

The ordering established by ExtendedXMLSaveImpl should be adjusted to be:
- xmlns
- xmlns:xsi
- xsi:schemaLocation

Please note that the wrong order is only produced by ExtendedXMLSaveImpl if it operates in a non-DOM mode (toDOM=false).

Class org.eclipse.sphinx.emf.resource.ExtendedXMLSaveImpl was adjusted to desired order of root attributes.
