I am writing a parser for converting XML.

public class TransformXML { public static void main(String[] args) { try { String filepath = "file:///C:\\Users\\Podolyak_EA\\Desktop\\Загрузка из xml\\примеры xml\\new\\75-2_.xml"; DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); Document doc = docBuilder.parse(filepath); // tag "Document" rename to "Form Node docTag = doc.getElementsByTagName("Document").item(0); doc.renameNode(docTag, "", "Form"); //tag "powerFacilitiesVid" rename to "powerFacility" Node pFVtag = doc.getElementsByTagName("powerFacilitiesVid").item(0); //delete tag powerFacilitiesVid deleteChildElement(doc, "Form", pFVtag.getNodeName()); String powerFacilityTag = "powerFacility"; addChildElement(doc, "Form", powerFacilityTag); //add child tag "vid" NodeList taglist = doc.getElementsByTagName("powerFacility"); Element el = null; for (int i = 0; i < taglist.getLength(); i++) { el = (Element) taglist.item(i); Element vid = doc.createElement("vid"); vid.appendChild(doc.createTextNode("10888")); el.appendChild(vid); } Node itemTag = doc.getElementsByTagName("item").item(0); addParentElement(doc, itemTag); TransformerFactory transformerFactory = TransformerFactory.newInstance(); Transformer transformer = transformerFactory.newTransformer(); DOMSource source = new DOMSource(doc); StreamResult result = new StreamResult(filepath); transformer.transform(source, result); } catch (ParserConfigurationException pce) { pce.printStackTrace(); } catch (IOException ioe) { ioe.printStackTrace(); } catch (org.xml.sax.SAXException e) { e.printStackTrace(); } catch (TransformerConfigurationException e) { e.printStackTrace(); } catch (TransformerException e) { e.printStackTrace(); } } public static void addChildElement(Document doc, String parentTagName, String addedTag){ NodeList nodeList = doc.getElementsByTagName(parentTagName); Element element = null; for (int i = 0; i < nodeList.getLength(); i++) { element = (Element)nodeList.item(i); Element myElement = doc.createElement(addedTag); element.appendChild(myElement); } } public static void deleteChildElement(Document doc, String parentTagname, String deletedTag){ NodeList nodeList = doc.getElementsByTagName(parentTagname); Element element = null; for (int i = 0; i < nodeList.getLength(); i++) { element = (Element)nodeList.item(i); Node deletedNode = element.getElementsByTagName(deletedTag).item(0); element.removeChild(deletedNode); } } public static void addParentElement( Document doc, Node currentChildNode){ }

Next, I need to wrap the existing tag with its contents in the parent tag, tell me the direction vector for writing the addParentElement method

    All the same, I wrote the method myself.

     public static void addParentElement( Document doc, Node childTag, Node parentsTag){ NodeList itemList = doc.getElementsByTagName(childTag.getNodeName()); for (int i = 0; i < itemList.getLength(); i++) { Element item = (Element) childTag; Element beanList = (Element) parentsTag; beanList.appendChild(item); } }
