1. Introduction<\/h2>\n
<\/div>\n

XML (eXtensible Markup Language)<\/a> is one of the most popular schemas for structuring information. Moreover, the parsing and manipulation of XML Documents<\/em> in Java are commonly accomplished using technologies like DOM (Document Object Model)<\/a>\u00a0and SAX (Simple API for XML)<\/a>.<\/p>\n

In some cases, it might be necessary to transform an XML Document <\/em>object into its string form, which could be used to store the XML information inside a database or to pass through over a network.<\/p>\n

In this tutorial, we\u2019ll discuss several ways of transforming an XML Document<\/em> object into a string in Java.<\/strong><\/p>\n

2. Example<\/h2>\n
<\/div>\n

Suppose we have the following Document<\/em> object:<\/p>\n

Document document = \/\/ ...<\/code><\/p>\n

This Document<\/em> object represents XML content in memory:<\/p>\n

<?xml version="1.0" encoding="UTF-8" standalone="no"?>\r\n<root>\r\n    <child1>This is child element 1<\/child1>\r\n    <child2>This is child element 2<\/child2>\r\n<\/root><\/code><\/pre>\n
Now, we need to convert this XML Document<\/em> object into a Java string.<\/p>\n
3. Using XML Transformation APIs<\/h2>\n
<\/div>\n
The javax.xml.transform<\/em><\/a> package in Java includes classes and interfaces for performing XML transformations. One of its capabilities is the conversion of an XML Document<\/em> object into a string representation. The following code demonstrates how to use the javax.xml.transform<\/em> package to parse this XML Document<\/em> object to a Java string:<\/p>\n
@Test\r\npublic void givenXMLDocument_whenUsingTransformer_thenConvertXMLToString()\r\nthrows TransformerException {  \r\n    TransformerFactory transformerFactory = TransformerFactory.newInstance();\r\n    Transformer transformer = transformerFactory.newTransformer();\r\n    StringWriter stringWriter = new StringWriter();\r\n    transformer.transform(new DOMSource(document), new StreamResult(stringWriter));\r\n    String result = stringWriter.toString();\r\n    assertTrue(result.contains("<root>"));\r\n    assertTrue(result.contains("This is child element 1"));\r\n    assertTrue(result.contains("This is child element 2"));\r\n}<\/code><\/pre>\n
We first instantiate a TransformerFactory<\/em> and a Transformer<\/em>, used for XML transformation. Then, we construct a StringWriter<\/em> to store the transformed XML in text form. Then, the transform()<\/em> method changes the XML Document<\/em>, and we can save it into the result<\/em> string using the stringWrite.toString()<\/em> method.<\/p>\n
4. Using Java XMLBeans<\/em><\/h2>\n
<\/div>\n
Converting between XML Document<\/em> and string is easy and flexible using the XmlBeans<\/em><\/a> approach in the Java XML manipulation world. We use XmlObject.Factory.parse(document)<\/em>, which parses the XML Document<\/em> into an XmlObject<\/em> for subsequent operative activities:<\/strong><\/p>\n
@Test\r\npublic void givenXMLDocument_whenUsingXmlBeans_thenConvertXMLToString() {\r\n    try {\r\n        XmlObject xmlObject = XmlObject.Factory.parse(document);\r\n        XmlOptions options = new XmlOptions();\r\n        options.setSavePrettyPrint();\r\n        options.setUseDefaultNamespace();\r\n        options.setSaveAggressiveNamespaces();\r\n        String xmlString = xmlObject.xmlText(options);\r\n        xmlString = "<?xml version=\\"1.0\\" encoding=\\"UTF-8\\" standalone=\\"no\\"?>" + xmlString;\r\n        assertTrue(xmlString.contains("<root>"));\r\n        assertTrue(xmlString.contains("This is child element 1"));\r\n        assertTrue(xmlString.contains("This is child element 2"));\r\n    } catch (XmlException e) {\r\n        e.printStackTrace();\r\n    }\r\n}<\/code><\/pre>\n
In the above test method, we parse the document into an XmlObject<\/em> using XmlOptions<\/em> to customize output formatting such as pretty-printing, namespaces, etc. Moreover, asserts<\/em> are done to establish that a resulting XML string contains an XML declaration and particular XML elements and element contents.<\/p>\n
