如何提高 Java 中针对 xsd 的大型 xml 验证的速度? [英] How to improve speed large xml validation against xsd in Java?

问题描述

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

I'm trying to validate a very XML (~200MB) against XSD. It's taking almost 3 hours. I'm not sure what am I doing wrong here?

    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);

推荐答案

查看 Marco Tedone 关于 XML 解组的这篇文章，参见 此处.根据他你可以看到 Stax

check this article on XML unmarshalling from Marco Tedone see here. Based on his you can see Stax

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