Validating the XML Format
Once the data file is extracted from the legacy system and converted to XML, it is important to validate the data file before to attempting to load it to the Windchill system. Any XML editor that performs validation against a DTD, such as XMLSpy, can be used for validating data against the standardX20.dtd.
The csvmapfile.dtd file is located in <Windchill>\codebase\registry\ixb\dtds\standardX20.dtd.
csvmapfile.dtd is not the complete DTD. For validation, the standardX20.dtd at <Windchill>\loadXMLFiles should be used.
Execute the UpdateEditDTDUtility to ensure standardX20.dtd is the most current version. For more information, see About UpdateEditDTDUtility.
Ensure that the following line is in your XML data files:
<!DOCTYPE NmLoader SYSTEM "standardX20.dtd">
