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

One of the most common data formats today is XML<\/a> (Extensible Markup Language), which is widely used in structuring and exchanging data between applications.<\/p>\n

Moreover, this use case is common in Java, where we must change some pieces of XML markup text to org.w3c.dom.Document<\/em> object.<\/p>\n

In this tutorial, we\u2019ll discuss converting a string with XML-based content into Org.w3c.dom.Document<\/em> in Java.<\/strong><\/p>\n

2. org.w3c.dom.Document<\/em><\/h2>\n
<\/div>\n

The org.w3c.dom.Document<\/em><\/a> is an integral component of the Document Object Model (DOM)<\/a> XML API in Java. This essential class represents an entire XML document and provides a comprehensive set of methods for navigating, modifying, and retrieving data from XML documents. When working with XML in Java, the org.w3c.dom.Document<\/em> object becomes an indispensable tool.<\/p>\n

To better understand how to create an org.w3c.dom.Document<\/em> object, let’s look at the following example:<\/p>\n

try {\r\n    \/\/ Create a DocumentBuilderFactory\r\n    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();\r\n    \/\/ Create a DocumentBuilder\r\n    DocumentBuilder builder = factory.newDocumentBuilder();\r\n    \/\/ Create a new Document\r\n    Document document = builder.newDocument();\r\n    \/\/ Create an example XML structure\r\n    Element rootElement = document.createElement("root");\r\n    document.appendChild(rootElement);\r\n    Element element = document.createElement("element");\r\n    element.appendChild(document.createTextNode("XML Document Example"));\r\n    rootElement.appendChild(element);\r\n    \r\n} catch (ParserConfigurationException e) {\r\n    e.printStackTrace();\r\n}<\/code><\/pre>\n
In the previous code, we start by creating the necessary elements for the parsing of XML, such as DocumentBuilderFactory<\/em> and DocumentBuilder<\/em>. After that, it builds a basic XML schema with an initial node element labeled “root”<\/em> encompassing another child node element referred to as “element”<\/em> that has the string “XML document example”<\/em>. Moreover, the XML output should be as follows:<\/p>\n
<root>\r\n    <element>XML Document Example<\/element>\r\n<\/root><\/code><\/pre>\n
3. Parsing XML from a String<\/h2>\n
<\/div>\n
Parsing of the XML string is needed for converting the string containing XML into an org.w3c.dom.Document<\/em>. Fortunately, there are several XML parsing libraries in Java, which include DOM<\/a>, SAX<\/a>, and StAX<\/a>.<\/p>\n
This article takes it easy by concentrating on the DOM parser for a simple explanation. Let’s walk through a step-by-step example of how to parse a string with XML and create an org.w3c.dom.Document<\/em> object:<\/p>\n
@Test\r\npublic void givenValidXMLString_whenParsing_thenDocumentIsCorrect()\r\n  throws ParserConfigurationException {\r\n    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();\r\n    DocumentBuilder builder = factory.newDocumentBuilder();\r\n    String xmlString = "<root><element>XML Parsing Example<\/element><\/root>";\r\n    InputSource is = new InputSource(new StringReader(xmlString));\r\n    Document xmlDoc = null;\r\n    try {\r\n        xmlDoc = builder.parse(is);\r\n    } catch (SAXException e) {\r\n        throw new RuntimeException(e);\r\n    } catch (IOException e) {\r\n        throw new RuntimeException(e);\r\n    }\r\n    assertEquals("root", xmlDoc.getDocumentElement().getNodeName());\r\n    assertEquals("element", xmlDoc.getDocumentElement().getElementsByTagName("element").item(0).getNodeName());\r\n    assertEquals("XML Parsing Example",\r\n      xmlDoc.getDocumentElement().getElementsByTagName("element").item(0).getTextContent());\r\n}<\/code><\/pre>\n
In the above code, we create a DocumentBuilderFactory<\/em> and DocumentBuilder<\/em> that are critical for XML parsing. Additionally, we define a sample XML string (xmlString<\/em>) that is converted into an InputSource<\/em> for parsing. We parse XML within a try-catch<\/em> block and catch<\/em> any possible exception like SAXException<\/em> or IOException<\/em>.<\/strong><\/p>\n
Finally, we employ a series of assertions to verify the correctness of the parsed XML document, including checks for the root element’s name using getDocumentElement().getNodeName()<\/em>, the child element’s name using getDocumentElement().getElementsByTagName()<\/em>, and the text content within the child element.<\/p>\n
4. Conclusion<\/h2>\n
<\/div>\n
In conclusion, for any competent Java developer who deals with XML-based data in numerous applications, from data processing to web services or configurational tasks, it is vital to know how to operate org.w3c.dom.Document<\/em> (NS).<\/p>\n
