2024년2월15일
XML을 예쁘게 인쇄한다는 것은 의도한 방식으로 XML 코드를 인쇄한다는 의미입니다. 이 자습서는 콘솔 및 XML 파일에서 XML을 예쁘게 인쇄하는 방법을 보여줍니다.
콘솔의 Pretty Print XML
아래 예제는 XML을 생성하고 콘솔에 출력하는 방법을 보여줍니다.
package delftstack;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
public class XML_Pretty_Print {
public static void main(String[] args) {
DocumentBuilderFactory Doc_Builder_Factory = DocumentBuilderFactory.newInstance();
DocumentBuilder Document_Builder;
try {
Document_Builder = Doc_Builder_Factory.newDocumentBuilder();
Document document = Document_Builder.newDocument();
// adding elements to Document
Element Root_Element = document.createElementNS("https://www.delftstack.com/", "Tutorials");
document.appendChild(Root_Element);
// add a first child element to the root element
Root_Element.appendChild(Get_Tutorial(document, "1",
"Perform String to String Array Conversion in Java",
"https://www.delftstack.com/howto/java/how-to-perform-string-to-string-array-conversion-in-java/",
"Java", "May-21, 2020"));
// add a second child
Root_Element.appendChild(Get_Tutorial(document, "2", "Compile a C++ Program Using GCC",
"https://www.delftstack.com/howto/cpp/gcc-compile-cpp/", "C++", "March-25, 2022"));
// add third child
Root_Element.appendChild(Get_Tutorial(document, "3", "Python Tutorial - Introduction",
"https://www.delftstack.com/tutorial/python-3-basic-tutorial/python-introduction/",
"Python", "January-29, 2018"));
// create output
TransformerFactory Transformer_Factory = TransformerFactory.newInstance();
Transformer transformer = Transformer_Factory.newTransformer();
// open indent for the xml code (Pretty Print)
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource Dom_Source = new DOMSource(document);
// Pretty Print the XML to Console
StreamResult XML_console = new StreamResult(System.out);
transformer.transform(Dom_Source, XML_console);
} catch (Exception e) {
e.printStackTrace();
}
}
private static Node Get_Tutorial(Document document, String id, String article_name, String link,
String programming_language, String date_created) {
Element tutorial = document.createElement("Tutorial");
// set the tutorial id attribute
tutorial.setAttribute("Id", id);
// create article name element
tutorial.appendChild(Get_Tutorial_Elements(document, tutorial, "ArticleName", article_name));
// create the Link element
tutorial.appendChild(Get_Tutorial_Elements(document, tutorial, "Link", link));
// create the Programming Language element
tutorial.appendChild(
Get_Tutorial_Elements(document, tutorial, "ProgrammingLanguage", programming_language));
// create Date Created element
tutorial.appendChild(Get_Tutorial_Elements(document, tutorial, "DateCreated", date_created));
return tutorial;
}
// method to create text node
private static Node Get_Tutorial_Elements(
Document document, Element element, String element_name, String element_value) {
Element element_node = document.createElement(element_name);
element_node.appendChild(document.createTextNode(element_value));
return element_node;
}
}

파일의 예쁜 인쇄 XML
파일에 XML을 예쁘게 인쇄하려면 XML 파일을 만들고 예쁜 인쇄 방식을 사용하여 해당 파일에 XML을 작성해야 합니다. 예를 참조하십시오:
package delftstack;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
public class XML_Pretty_Print {
public static void main(String[] args) {
DocumentBuilderFactory Doc_Builder_Factory = DocumentBuilderFactory.newInstance();
DocumentBuilder Document_Builder;
try {
Document_Builder = Doc_Builder_Factory.newDocumentBuilder();
Document document = Document_Builder.newDocument();
// adding elements to Document
Element Root_Element = document.createElementNS("https://www.delftstack.com/", "Tutorials");
document.appendChild(Root_Element);
// add a first child element to the root element
Root_Element.appendChild(Get_Tutorial(document, "1",
"Perform String to String Array Conversion in Java",
"https://www.delftstack.com/howto/java/how-to-perform-string-to-string-array-conversion-in-java/",
"Java", "May-21, 2020"));
// add a second child
Root_Element.appendChild(Get_Tutorial(document, "2", "Compile a C++ Program Using GCC",
"https://www.delftstack.com/howto/cpp/gcc-compile-cpp/", "C++", "March-25, 2022"));
// add third child
Root_Element.appendChild(Get_Tutorial(document, "3", "Python Tutorial - Introduction",
"https://www.delftstack.com/tutorial/python-3-basic-tutorial/python-introduction/",
"Python", "January-29, 2018"));
// create output
TransformerFactory Transformer_Factory = TransformerFactory.newInstance();
Transformer transformer = Transformer_Factory.newTransformer();
// open indent for the xml code (Pretty Print)
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource Dom_Source = new DOMSource(document);
// Create a file and write XML to it
StreamResult XML_file = new StreamResult(new File("delftstack.xml"));
// write data
transformer.transform(Dom_Source, XML_file);
System.out.println("The XML file has been Generated");
} catch (Exception e) {
e.printStackTrace();
}
}
private static Node Get_Tutorial(Document document, String id, String article_name, String link,
String programming_language, String date_created) {
Element tutorial = document.createElement("Tutorial");
// set the tutorial id attribute
tutorial.setAttribute("Id", id);
// create article name element
tutorial.appendChild(Get_Tutorial_Elements(document, tutorial, "ArticleName", article_name));
// create the Link element
tutorial.appendChild(Get_Tutorial_Elements(document, tutorial, "Link", link));
// create the Programming Language element
tutorial.appendChild(
Get_Tutorial_Elements(document, tutorial, "ProgrammingLanguage", programming_language));
// create Date Created element
tutorial.appendChild(Get_Tutorial_Elements(document, tutorial, "DateCreated", date_created));
return tutorial;
}
// method to create text node
private static Node Get_Tutorial_Elements(
Document document, Element element, String element_name, String element_value) {
Element element_node = document.createElement(element_name);
element_node.appendChild(document.createTextNode(element_value));
return element_node;
}
}
위의 코드는 예쁜 인쇄 방식을 사용하여 XML을 파일에 씁니다.
출력:
The XML file has been Generated
