PMC SGML Validator
Use this tool to validate SGML files that will be submitted to PMC. The DTD must be declared in a properly formed DOCTYPE definition, and the DTD must have already been submitted to PMC.
Enter the path or browse to your SGML file and click "Check File". You results will be returned to you momentarily.
Hit "Clear" to return to a clean form.
Please contact pubmedcentral@nih.gov if you have any problems with the tool.
