Inserting a DOCTYPE declaration into DOM

[Kathy Rogers]

Hi,
I'm creating an XML file by building up a DOM document in some java code and then writing out the file. But I would like to know how to associate a DTD file with the XML file by inserting the DOCTYPE declaration. So that I end up with some similar to the following when I finally write the DOM Document out to a file:-

<?xml version="1.0"?>
<!DOCTYPE envelope SYSTEM "Master_catalogv1.dtd">
<XMLDocument>........</XMLDocument>

Any help gratefully received!
Kathy

hi kathy,
i don't know if you are using any ibm packages,if so use com.ibm.xml.parser.TXDoument doc = new com.ibm.xml.parser.TXDoument();
doc.createDTD(String,new ExternalID("aaa.dtd"));
i think this would help.

Hi Kathy ,
i had found out including external dtd in the dom.
see if this works,
//from package oracle.xml.parser.v2.XMLDocument and XMLDeclPI
XMLDocument doc = new XMLDocument();

XMLDeclPI decl = new XMLDeclPI("1.0",null,null,false);//version,encoding and standalone parameters
doc.appendChild(decl);
doc.setDoctype("rootelement","full path of the external dtd",null);// not sure of the last parameter.
bye,
lavanya

Thanks for your help, Lavanya. The problem is that I'm not using the IBM parser - I'm using a parser that comes packaged with an application we use for B2B transactions and we haven't really been given any API information for it despite requests. Finally I fell back on this:-

destination = XmlHelper.createDocument();
DOM implementation domImp = destination.getImplementation();
Document dtd = domImp.createDocumentType("envelope", null, "catalog.dtd");
destination = domImp.createDocument(null, "envelope", dtd);

Not a very elegant solution as it involves creating and then immediately trashing a dom object just to get the implementation but it works well enough.
Thanks again,
Kathy
