我有这样的 .xml 文件。我想将此文件转换为 HashMap 并在 Java 中反转。您能告诉我如何将其转换为 HashMap 文件吗？谢谢 ...
这是 .xml 文件：
<RelationShipTypes>
<RelationShipType key="1" name="Organization Unit"/>
<RelationShipType key="2" name="Employee"/>
<RelationShipType key="3" name="Customer"/>
<RelationShipType key="4" name="Supplier"/>
<RelationShipType key="5" name="Agency"/>
<RelationShipType key="6" name="Partner"/>
<RelationShipType key="7" name="SALES AGENT"/>
<RelationShipType key="8" name="End User"/>
<RelationShipType key="9" name="Other"/>
</RelationShipTypes>
这是代码：
public static Map<String, String> convertNodesFromXml(String xml) throws SAXException, IOException, ParserConfigurationException {
try {
InputStream is = new ByteArrayInputStream(xml.getBytes());
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(is);
return createMap(document.getDocumentElement());
} catch (SAXException ex) {
Logger.getLogger(BaseDataLoader.class.getName()).log(Level.SEVERE, null, ex);
throw ex;
} catch (IOException ex) {
Logger.getLogger(BaseDataLoader.class.getName()).log(Level.SEVERE, null, ex);
throw ex;
} catch (ParserConfigurationException ex) {
Logger.getLogger(BaseDataLoader.class.getName()).log(Level.SEVERE, null, ex);
throw ex;
}
}
public static Map<String, String> createMap(Node node) {
Map<String, String> map = new HashMap<String, String>();
NodeList nodeList = node.getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++) {
Node currentNode = nodeList.item(i);
if (currentNode.hasAttributes()) {
for (int j = 0; j < currentNode.getAttributes().getLength(); j++) {
Node item = currentNode.getAttributes().item(i);
map.put(item.getNodeName(), item.getTextContent());
}
}
if (node.getFirstChild() != null && node.getFirstChild().getNodeType() == Node.ELEMENT_NODE) {
map.putAll(createMap(currentNode));
} else if (node.getFirstChild().getNodeType() == Node.TEXT_NODE) {
map.put(node.getLocalName(), node.getTextContent());
}
}
return map;
}
