问题


I'm in a part of an application where I have an access to the xmlStreamReader which is representing the XML file needed to be fully read into a String.

Is there a way to obtain the XML content without building another xmlStreamReader or using another stream on the file?

import javax.xml.stream.XMLStreamReader;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerFactoryConfigurationError;
import javax.xml.transform.stax.StAXSource;
import javax.xml.transform.stream.StreamResult;

private String getOuterXml(XMLStreamReader xmlr) throws TransformerConfigurationException,
    TransformerFactoryConfigurationError, TransformerException
{
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    StringWriter stringWriter = new StringWriter();
    transformer.transform(new StAXSource(xmlr), new StreamResult(stringWriter));
    return stringWriter.toString();
}
