java - 从 sax validator 获取更多信息

Question

我可以从 validator 中获取例如节点结构或类似的东西吗？像听众或处理程序之类的东西。异常(exception)是不够的。我必须选择发生错误的节点。这就是我到目前为止所构建的。

def factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI)
def schema = factory.newSchema(new StreamSource(new FileReader("src/import.xsd")))
def validator = schema.newValidator()
try {
    validator.validate(new StreamSource(new FileReader("src/import.xml")))
    println "everything is fine"
} catch(SAXException e) {   
    println e
}

谢谢。

解析时进行验证。这是 Java 代码，看起来翻译成 Groovy 应该非常简单:

InputStream xml = // …
InputStream xsd = // …

SchemaFactory xsFact = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = xsFact.newSchema(new StreamSource(xsd));

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
dbf.setValidating(false);
dbf.setSchema(schema);
DocumentBuilder db = dbf.newDocumentBuilder();

Document dom = db.parse(new InputSource(xml));
