Detailed Description

A parsed and, optionally, repaired document is represented by Tidy as a Tree, much like a W3C DOM. This tree may be traversed using these functions. The following snippet gives a basic idea how these functions can be used.

void dumpNode( TidyNode tnod, int indent )
{
  TidyNode child;

  for ( child = tidyGetChild(tnod); child; child = tidyGetNext(child) )
  {
    ctmbstr name;
    switch ( tidyNodeGetType(child) )
    {
    case TidyNode_Root:       name = "Root";                    break;
    case TidyNode_DocType:    name = "DOCTYPE";                 break;
    case TidyNode_Comment:    name = "Comment";                 break;
    case TidyNode_ProcIns:    name = "Processing Instruction";  break;
    case TidyNode_Text:       name = "Text";                    break;
    case TidyNode_CDATA:      name = "CDATA";                   break;
    case TidyNode_Section:    name = "XML Section";             break;
    case TidyNode_Asp:        name = "ASP";                     break;
    case TidyNode_Jste:       name = "JSTE";                    break;
    case TidyNode_Php:        name = "PHP";                     break;
    case TidyNode_XmlDecl:    name = "XML Declaration";         break;

    case TidyNode_Start:
    case TidyNode_End:
    case TidyNode_StartEnd:
    default:
      name = tidyNodeGetName( child );
      break;
    }
    assert( name != NULL );
    printf( "\%*.*sNode: \%s\\n", indent, indent, " ", name );
    dumpNode( child, indent + 4 );
  }
}

void dumpDoc( TidyDoc tdoc )
{
  dumpNode( tidyGetRoot(tdoc), 0 );
}

void dumpBody( TidyDoc tdoc )
{
  dumpNode( tidyGetBody(tdoc), 0 );
}
