XML problem

If my program try to parse a xml file which starts with
<?xml version="1.0"?>
<!DOCTYPE symbolDefinition SYSTEM "C:\symbol.dtd">
it gives an error. The program works fine if the xml file starts with
<?xml version="1.0"?>
<!DOCTYPE symbolDefinition SYSTEM "symbol.dtd">
.
The error says its something to do with URI but I don't know how to over come this problem. The file "symbol.dtd" exists in the correct directory.

the following is the code to parse XML files.

Thanx

DocumentBuilderFactory factory
= DocumentBuilderFactory.newInstance();
factory.setValidating(true);
factory.setIgnoringElementContentWhitespace(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(zin);

Can you post the exact error messages and the versoin of XML parser you are using? Latest versions of Xerces have problems with paths since the expect everything to be a URI.

It's rather long error
org.xml.sax.SAXParseException: Relative URI "C:\symbol.dtd"; can not be reso
lved without a base URI.

Isn't it
<!DOCTYPE symbolDefinition SYSTEM "file://C:/symbol.dtd">

?

girionis

Hmm... I think it is without the ":". Try it with both and see if it works.
