validation stops,error message prefix cant be resolved at namespace URI
I am currently working in a translation project where I have to translate the xml files to my native language in english,after completing translation I have to validate them and then submit them after fixing the errors in xml,
I am familiar with tags of html and xml although I have never used them for development,
while trying to validate the file in a validator
a certain prefix cant be resolved in the namespace URI
although that prefix worked in the previous namespaces
so should I need to check the name space URI in the main file of DTD?
