我已经看过使用JAVA进行解析但我需要使用javascript或perl解析相同的IFC扩展文件，其中包含面向对象的框架和实体表示的块。 一个基本的想法会很有帮助。
示例IFC文件：
ISO-10303-21;
HEADER;
FILE_DESCRIPTION(('ViewDefinition [CoordinationView]'),'2;1');
FILE_NAME(
/* name */ 'C:\\sample.ifc',
/* time_stamp */ '2012-05-18T13:15:15',
/* authorization */ 'None');
FILE_SCHEMA (('IFC2X3'));
ENDSEC;
DATA;
#1= IFCAPPLICATION(#2,'0.5.29.0','ssiRhinoIFC - Geometry Gym Plug-in for Rhino3d','ssiRhinoIFC');
#2= IFCORGANIZATION($,'Geometry Gym Pty Ltd',$,$,$);
#3= IFCPERSONANDORGANIZATION(#4,#5,$);
#4= IFCPERSON($,'Jon',$,$,$,$,$,$);
#5= IFCORGANIZATION($,'UNKNOWN',$,$,$);
#6= IFCOWNERHISTORY(#3,#1,$,.ADDED.,1337346830,$,$,1337346830);
#7= IFCCARTESIANPOINT((0.0,0.0,0.0));
#8= IFCDIRECTION((1.0,0.0,0.0));
ENDSEC;
END-ISO-10303-21;
