Element library contains methods that can be used to manipulate elements in 3DMLW document.

• int  attributeInt( name : string )
  An integer representation of value stored in attribute.

  <document id='doc1' version='1.0' stylesheet='{#default}' v='15'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");   -- Gets element with id doc1
      print(elem:attributeInt("v")); -- Prints out 15
    </script>
  </document> 

• float  attributeFloat( name : string )
  A floating point representation of value stored in attribute.

  <document id='doc1' version='1.0' stylesheet='{#default}' v='15.5'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");   -- Gets element with id doc1
      print(elem:attributeFloat("v")); -- Prints out 15.5
    </script>
  </document> 

• string  attributeString( name : string )
  A string representation of value stored in attribute.

  <document id='doc1' version='1.0' stylesheet='{#default}'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");   -- Gets element with id doc1
      print(elem:attributeString("id")); -- Prints out doc1
    </script>
  </document> 

• bool  attributeBool( name : string )
  A boolean representation of value stored in attribute.

  <document id='doc1' version='1.0' stylesheet='{#default}' v='false'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");   -- Gets element with id doc1
      print(elem:attributeBool("v")); -- Prints out false
    </script>
  </document> 

•  putAttribute( name : string , value : any )
  

  <document id='doc1' version='1.0' stylesheet='{#default}' v='false'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");    -- Gets element with id doc1
      elem:putAttribute("v", true);   -- Set doc1 attribute v to true
      print(elem:attributeBool("v")); -- Prints out true
    </script>
  </document> 

•  putReference( name : string , value : reference )
  

  <document id='doc1' version='1.0' stylesheet='{#default}' v='false'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");         -- Gets element with id doc1
      elem:putReference("v", "#mesh01:x"); -- Set doc1 attribute v to point to #mesh01:x
      print(elem:attributeFloat("v"));     -- Prints out mesh01 coordinate x
    </script>
  </document> 

•  addChild( type : string )
  

  <document id='doc1' version='1.0' stylesheet='{#default}' v='false'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");      -- Gets element with id doc1
      child=elem:addChild("content2d"); -- Adds content2d element to parent
    </script>
  </document> 

•  removeChild( type : Element )
  

  <document id='doc1' version='1.0' stylesheet='{#default}' v='false'>
    <script type='text/x-lua'>
      elem=Reference.get("#doc1");      -- Gets element with id doc1
      child=elem:addChild("content2d"); -- Adds content2d element to parent
      elem:removeChild(child);          -- Removes content2d element from parent
