Finally submitted my master thesis. Have a look if you want: Online XML Editor Based On XML Schema
This master thesis introduces a mechanism of mapping XML Schema (XSD) to PHP. In the mapping process PHP classes are automatically generated which include all the functionality defined by the schema. The second achievement is an online syntax-directed editor based on the above defined mapping to friendly create Extensible Markup Language (XML) documents based on the mapped schema. In addition the editor offers several guidance mechanisms to create complex XML documents online.
Stay tuned for more updates soon.
