[英]how to generate formatted .xml file?
I'm writing a program that produces an xml file. 我正在编写一个生成xml文件的程序。 The code works perfectly giving the expected result.But it gives me only a single line document.
该代码可以完美地提供预期的结果,但是它只给我一个单行文档。 I want it to be in formatted way and correctly indented.Is there a way to do that?
我希望它采用格式化的方式并正确缩进,有没有办法做到这一点? Here is the code i used
这是我使用的代码
public class Main {
public static void main(String[] args) {
WriteXml(7, 9, 0);
}
public static void WriteXml(int WS1, int FTP1, int EMAIL1) {
try {
final DocumentBuilderFactory documentFactory = DocumentBuilderFactory.newInstance();
final DocumentBuilder documentBuilder = documentFactory.newDocumentBuilder();
final Document document = documentBuilder.newDocument();
final Element root = document.createElement("Counter");
document.appendChild(root);
final Element properties = document.createElement("properties");
root.appendChild(properties);
final Element webservice = document.createElement("age");
webservice.appendChild(document.createTextNode(Integer.toString(WS1)));
properties.appendChild(webservice);
final Element ftp = document.createElement("id");
ftp.appendChild(document.createTextNode(Integer.toString(FTP1)));
properties.appendChild(ftp);
final Element email = document.createElement("grade");
email.appendChild(document.createTextNode(Integer.toString(EMAIL1)));
properties.appendChild(email);
final TransformerFactory transformerFactory = TransformerFactory.newInstance();
final Transformer transformer = transformerFactory.newTransformer();
final DOMSource domSource = new DOMSource(document);
final StreamResult streamResult = new StreamResult(new File("src/counter.xml"));
transformer.transform(domSource, streamResult);
} catch (final Exception e) {
e.printStackTrace();
}
}
}
and this gives me the following xml document 这给了我下面的xml文档
<?xml version="1.0" encoding="UTF-8" standalone="no"?><Counter><properties><age>7</age><id>9</id><grade>0</grade></properties></Counter>
But i want it to be more like this 但我希望它更像这样
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Counter>
<properties>
<age>7</age>
<id>9</id>
<grade>0</grade>
</properties>
</Counter>
您可以在变压器的输出上设置几个属性,其中一个用于缩进:
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
With some guessing and after looking at this question adding these lines after obtaining the transformer might do the trick 经过一些猜测,在看了这个问题之后,在获得变压器后添加了这些线可能会解决问题
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
Underscore-java library has static method U.formatXml(xmlstring). Underscore -java库具有静态方法U.formatXml(xmlstring)。 I am the maintainer of the project.
我是该项目的维护者。 Live example
现场例子
import com.github.underscore.lodash.U;
String formattedXml = U.formatXml(xmlstring);
I created the following method: 我创建了以下方法:
public String prettyPrintXml(String xmlStringToBeFormatted) {
String formattedXmlString = null;
try {
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
documentBuilderFactory.setValidating(true);
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
InputSource inputSource = new InputSource(new StringReader(xmlStringToBeFormatted));
Document document = documentBuilder.parse(inputSource);
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
StreamResult streamResult = new StreamResult(new StringWriter());
DOMSource dOMSource = new DOMSource(document);
transformer.transform(dOMSource, streamResult);
formattedXmlString = streamResult.getWriter().toString().trim();
} catch (Exception ex) {
ex.printStackTrace(System.err);
}
return formattedXmlString;
}
