Propagating Changes to XML and DTD
1. Make your changes to the CSV data file.
2. Make your changes to \Windchill\loadFiles\csvmapfile.txt.
3. Modify the csvmapfile.dtd as required based on your changes.
4. Run the following utility to update the /loadXMLFiles/standardX20.dtd file to reflect your changes:
windchill wt.load.util.UpdateEditDTDUtility
5. Run the following utility to generate XML load files:
windchill wt.load.util.CSV2XML -input [optional] -output [optional] -root [optional] -h [optional] -encoding [optional] -mapfile <absolute path of the csvmapfile.txt> -delimiter <user specified delimiter> -preservespace [specifies if spaces should be preserved]
For details about the CSV2XML arguments, see CSV2XML Arguments.
6. Validate the XML file against the DTD and test your changes.
