在Java中解析XML时，请保留数字字符实体字符（例如``）

您需要先将所有XML实体转义，然后再将文件解析为

document

&``&

documentBuilder documentBuilder =        documentBuilderFactory.newInstance().newdocumentBuilder();String xmlContents = new String(Files.readAllBytes(Paths.get("demo.xml")), "UTF-8");document document = documentBuilder.parse(         new InputSource(new StringReader(xmlContents.replaceAll("&", "&"))        ));

输出：

2A string followed by special symbols
