Hi all
I am new to xml,
I am using DOM parser for xml parsing, before i am going to parse my xml file I want to validating my xml file against the .dtd. could someone tell as how to do this. if possible please give me sample code.
I have written code for parsing xml as below
try{
//Create Document
Document doc = null;
DocumentBuilderFactory dbf =DocumentBuilderFactory.newInstance();
dbf.setValidating(true);
DocumentBuilder db = dbf.newDocumentBuilder();
File file = new File(XMLFILE);
doc = db.parse(file);
NodeList nl = doc.getElementsByTagName("ITestFrame");
---statements
--statements
--
--
--
}catch(IOException e){
System.out.println("Caught Exception : "+e);
}
here before going for parsing i want check XMLFILE is according to dtd or not.
do we have any method for that.
Thanks
Vishnu

This topic is more appropriate to the xml forum. I'll move it there for you.

You don't need to call any method for doing the validation -- the parse(...) method does that behind the scenes if you've configured the parser to do validation.
You can use this sample as a base for your DTD validation. You basically need to just drop the ".../validation/schema" feature.
