java - 如何提高 Java 中针对 xsd 的大型 xml 验证速度？

Question

我正在尝试针对 XSD 验证非常 XML (~200MB)。这需要将近3个小时。我不确定我在这里做错了什么？

    SchemaFactory sf = SchemaFactory.newInstance(W3C_XML_SCHEMA_NS_URI);
    Schema schema = sf.newSchema(new File(this.productExtraInfoXsd));

    DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
    domFactory.setNamespaceAware(true);
    DocumentBuilder builder = domFactory.newDocumentBuilder();
    Document doc = builder.parse(new File(filePath));

    DOMSource domSource = new DOMSource(doc);
    DOMResult result = new DOMResult();

    Validator validator = schema.newValidator();
    validator.validate(domSource, result);

查看这篇来自 Marco Tedone 的关于 XML 解码的文章，请参阅 here .基于他你可以看到Stax

XMLInputFactory xmlInputFactory = XMLInputFactory.newInstance();
XMLStreamReader xmlStreamReader = xmlInputFactory.createXMLStreamReader(fileInputStream);
Validator validator = schema.newValidator();
validator.validate(new StAXSource(xmlStreamReader));
