简介
EntityReference 节点可用于表示树中的实体引用。 (机器翻译)
final var xml = """
<!DOCTYPE root [
<!ENTITY aaa "bbb">
<!ENTITY xxx "yyy">
]>
<root/>
""";
final var factory = DocumentBuilderFactory.newInstance();
final var builder = factory.newDocumentBuilder();
final var document = builder.parse(new ByteArrayInputStream(xml.getBytes()));
final var root = document.getDocumentElement();
System.out.println(root); // [root: null]
final var entityReferenceA = document.createEntityReference("aaa");
System.out.println(entityReferenceA); // [aaa: null]
root.appendChild(entityReferenceA);
final var entityReferenceX = document.createEntityReference("xxx");
System.out.println(entityReferenceX); // [xxx: null]
root.appendChild(entityReferenceX);
final var domImpl = builder.getDOMImplementation();
if (domImpl.getFeature("LS", "3.0") instanceof DOMImplementationLS ls) {
final var serializer = ls.createLSSerializer();
final var str = serializer.writeToString(document);
//<?xml version="1.0" encoding="UTF-16"?><!DOCTYPE root [
//<!ENTITY aaa 'bbb'>
//<!ENTITY xxx 'yyy'>
//]>
//<root>&aaa;&xxx;</root>
System.out.println(str);
