org.w3c.dom.Document 개체를 문자열로 변환하고 싶습니다. 저는 Java 6을 사용하고 있으며 작업에 필요한 모든 (완전 무료) 기술을 사용할 수 있습니다. 이 스레드에서 솔루션을 시도했습니다. 이 코드보다 Java에서 XML 문서를 문자열로 변환하는 더 우아한 방법이 있습니까? , 그들이있는 곳
DOMImplementationLS domImplementation = (DOMImplementationLS) doc.getImplementation();
LSSerializer lsSerializer = domImplementation.createLSSerializer();
String html = lsSerializer.writeToString(doc);
그러나 다음과 같은 끔찍한 예외로 맞이했습니다.

변형을해도 괜찮다면 시도해 볼 수 있습니다.
DocumentBuilderFactory domFact = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = domFact.newDocumentBuilder();
Document doc = builder.parse(st);
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
System.out.println("XML IN String format is: \n" + writer.toString());
답변
같은 것을 사용하십시오
import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
//method to convert Document to String
public String getStringFromDocument(Document doc)
{
try
{
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
return writer.toString();
}
catch(TransformerException ex)
{
ex.printStackTrace();
return null;
}
}
답변
이 페이지에 설명 된대로 이것은 나를 위해 일했습니다 .
TransformerFactory tf = TransformerFactory.newInstance();
Transformer trans = tf.newTransformer();
StringWriter sw = new StringWriter();
trans.transform(new DOMSource(document), new StreamResult(sw));
return sw.toString();

Zaz의 답변을 기반으로 한 Scala 버전.
case class DocumentEx(document: Document) {
def toXmlString(pretty: Boolean = false):Try[String] = {
getStringFromDocument(document, pretty)
}
}
implicit def documentToDocumentEx(document: Document):DocumentEx = {
DocumentEx(document)
}
def getStringFromDocument(doc: Document, pretty:Boolean): Try[String] = {
try
{
val domSource= new DOMSource(doc)
val writer = new StringWriter()
val result = new StreamResult(writer)
val tf = TransformerFactory.newInstance()
val transformer = tf.newTransformer()
if (pretty)
transformer.setOutputProperty(OutputKeys.INDENT, "yes")
transformer.transform(domSource, result)
Success(writer.toString);
}
catch {
case ex: TransformerException =>
Failure(ex)
}
}
이를 통해 둘 중 하나를 수행하거나 함수를 doc.toXmlString()호출 할 수 있습니다 getStringFromDocument(doc).
