A more elegant way is transforming the result in JDOM
- http://www.jdom.org (or another DOM) and using the
associated API.
Example:
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;
import org.jdom.JDOMException;
import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.xmldb.api.*;
...
ResourceSet resultSet = this.service.query(this.xpathQuery);
ResourceIterator results = resultSet.getIterator();
while (results.hasMoreResources()) {
Resource res = results.nextResource();
String resu = (String) res.getContent();
// create JDOM Element
Element resultElement = jdomEl(resu);
...
}
private Element jdomEl(String xmlInput) throws JDOMException {
Element el = new Element("dummy");
try {
SAXBuilder builder = new SAXBuilder(false);
Document doc = builder.build(new StringReader(xmlInput));
el = (Element)doc.getRootElement().clone();
} catch (JDOMException e) {
e.printStackTrace();
} finally {
return el;
}
}
