Question

我发现了一个问题，但似乎这是一个老问题，答案不再有效Java XML processing entity problem?

所以我的问题是我实际上使用的是XML文件，它确实有Entity References。我希望这些实体引用保留，DocumentBuilder不要解析它。但是它尝试解析它然后我得到The entity "entityname" was referenced, but not declared.异常。

这是我的XmlParser类构造函数：

public XmlParser(File file) throws ParserConfigurationException,
        SAXException, IOException {
    String provider = "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl";
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(provider, null);
    factory.setExpandEntityReferences(false);
    factory.setValidating(false);
    factory.setFeature(
            "http://apache.org/xml/features/nonvalidating/load-external-dtd",
            false);
    DocumentBuilder dBuilder = factory.newDocumentBuilder();
    document = dBuilder.parse(file);
    document.getDocumentElement().normalize();
}

我还尝试使用DocumentBuilderFactory.newInstance()而没有任何参数，并得到了相同的错误。

如何解决此问题？

示例XML：

<?xml version="1.0" encoding="UTF-8"?>
<chapter >
    <title>&entityname; Some Title</title>
</chapter>

例外：

[Fatal Error] NHS.xml.keyref:3:21: The entity "entityname" was referenced, but not declared.
Exception in thread "main" org.xml.sax.SAXParseException; systemId: file:/C:/somedir/NHS.xml.keyref; lineNumber: 3; columnNumber: 21; The entity "entityname" was referenced, but not declared.

引用了实体“entityname”，但未声明
