XML Script

Model can be saved as a XML document. The resulting file uses the extension “.xml”.

Using the XML format is possible to write incomplete script having functors whose input and output ports are not completely bound. This allows saving models in the first development stages.

The XML document is written according to the following DTD ¹⁾:

<?xml version="1.0"?>
<!DOCTYPE script [
  <!ELEMENT script (property*, functor*, containerfunctor*)>
 
  <!ELEMENT functor (property*, inputport*, outputport*)>
    <!ATTLIST functor
      name   CDATA  #REQUIRED>
 
  <!ELEMENT containerfunctor (property*, inputport*, outputport*, internalinputport*, internaloutputport*, functor*)>
    <!ATTLIST containerfunctor
      name   CDATA  #REQUIRED>
 
  <!ELEMENT property EMPTY>
    <!ATTLIST property
      key  CDATA  #REQUIRED
      value  CDATA  #REQUIRED>
 
  <!ELEMENT inputport (#PCDATA)>
    <!ATTLIST inputport
      name   CDATA  #REQUIRED
      peerid IDREFS #IMPLIED>
  <!ELEMENT outputport EMPTY>
    <!ATTLIST outputport
      name   CDATA  #REQUIRED
      id   ID   #REQUIRED>
   <!ELEMENT internalinputport EMPTY>
    <!ATTLIST internalinputport
      name   CDATA  #REQUIRED
      peerid IDREFS #IMPLIED>
  <!ELEMENT internaloutputport EMPTY>
    <!ATTLIST internaloutputport
      name   CDATA  #REQUIRED
      id   ID   #REQUIRED>
]>

The resulting document is not formated using tabs, spaces or newlines. Those characters are written only when they are inside the definition content, not in the content boundaries.

Below it is an example of a XML script:
