В этой задаче я пытаюсь изменить значения полей ввода текста на переменные, полученные в результате разбиения большой строки. XML содержит обычный HTML-код, но мне было интересно, можно ли выполнить эту задачу с помощью Java (не Javascript). XML-файл является стандартным файлом и не может быть отредактирован.

customerDataEntryTabs.xml

Например, я хотел бы изменить значение в поле ввода текста с идентификатором («tab0Field0Input»), найденным в xml-файле, на переменную (имя), найденную в коде java.

Вы можете использовать org.w3c.dom.Document . Это синтаксический анализатор XML, и он уже включен в Java без каких-либо сторонних библиотек.

Вы можете превратить свой XML-файл в a Document , а затем получить доступ к нужным вам полям и изменить их значения.

Это было бы примером:

 // Reading the file and turning it into a Document File xmlFile = new File("customerDataEntryTabs.xml"); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); DocumentBuilder builder = factory.newDocumentBuilder(); Document doc = builder.parse(xmlFile);  // Getting all input elements NodeList inputElements = doc.getElementsByTagName("input");  // Traversing all input elements for (int i = 0; i lt; inputElements.getLength() ; i  ) {  Element currentInputElement = (Element) inputElements.item(i);   Node idNode = currentInputElement.getAttributes().getNamedItem("id"); //Getting the ID of the element  if(idNode != null)  {  if(idNode.getTextContent().equals("tab0Field0Input")) // Checking if the ID is equal to what you actually want  {  currentInputElement.setAttribute("value", "YOUR VALUE COMES HERE"); // Setting the Value of the input element  }  } }  // Transforming the result document to a string... Transformer trans = TransformerFactory.newInstance().newTransformer(); trans.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); trans.setOutputProperty(OutputKeys.INDENT, "yes");  StringWriter sw = new StringWriter(); trans.transform(new DOMSource(doc), new StreamResult(sw));  String resultXml = sw.toString();  

После того , как вы получите String его, вы можете делать с ним все, что захотите.

Сначала загрузите файл в память, затем отредактируйте значения и, наконец, запишите файл обратно.

 File xmlFile = new File("customerDataEntryTabs.xml"); String newValue = "whatever is your new value";  // parse file DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document doc = builder.parse(xmlFile);  // find location to edit and apply new value - we do that using XPath XPath xpath = XPathFactory.newInstance().newXPath(); Element input = (Element)xpath.evaluate("//input[@id='tab0Field0Input']", doc, XPathConstants.NODE) input.setAttribute("value", newValue);  // write back the file - we serialize using XSLT Transformer t = TransformerFactory.newInstance().newTransformer(); t.transform(new DomSource(dom), new StreamResult(new FileOutputStream(xmlFile)));
