Hi Dhanji,
you can override org.dom4j.DocumentFactory and you can insert yout own
Locator2 (with setDocumentLocator() method) into
org.dom4j.io.SAXContentHandler, so you can obtain location information
from your Locator. Than you can read the location information from
supplied Locator in DocumentFactory and write down this info at newly
created node – into some Map, or you can override DefaultElement,
DefaultAttribute and so on and write location information to your
overriden instances of these classes.
There is no way how to obtain the location information from DOM4J
without overriding classes, because DOM representation of XML has no
relationship with XML in file with lines and columns, so it doesn't
make sense to store this information somewhere in DOM4J standard
classes.
Somethink like this:
org.xml.sax.Locator locator = new …;
DocumentFactory documentFactory = new DocumentFactoryWithLocator(locator);
SAXContentHandler contentHandler = new SAXContentHandler(documentFactory );
contentHandler.setDocumentLocator(locator);
org.xml.sax.XMLReader reader = …;
reader.setContentHandler(contentHandler );
reader.parse(…);
Document document = contentHandler.getDocument();
In DocumentFactoryWithLocator you will have methods like this:
public Element createElement(QName qname) {
ElementWithLocation element = new ElementWithLocation (qname);
element.setLocation(locator.getLineNumber(), locator.getColumnNumber());
return element;
}
And so on…
Sincerely,
Filip Jirsák
