java - "error: cvc-elt.1: Invalid type"在 Java 中验证 xml 时

Question

我在用 Java 验证 XML 文件时遇到问题，我不断收到“无效类型”错误。我一直在谷歌搜索并找到了一些 SO 线程，它们告诉我在 XML 中添加 namespace 并在各处添加“ns:”，但无济于事。

XML:

<ns:Content xmlns:ns="http://namespace">
  <ns:Request>
    <ns:FromDateTime>20130726161606</ns:FromDateTime>
    <ns:RemainderOffset/>
    <ns:MaxResults>100</ns:MaxResults>
  </ns:Request>
  <ns:Response>
    <ns:Status>
      <ns:Code>200</ns:Code>
    </ns:Status>
    <ns:Remainder>
      <ns:Count>2828</ns:Count>
      <ns:Offset>126690959</ns:Offset>
    </ns:Remainder>
    <ns:Items>
      <ns:Item id="126752560" itemHash="-1686318559">
        <ns:Title>[…]</ns:Title>
        <ns:Description>[…]</ns:Description>
        <ns:PubDate>Thu, 05 Sep 2013 06:00:27 GMT</ns:PubDate>
        <ns:Uri>[…]</ns:Uri>
        <ns:Resource>[…]</ns:Resource>
        <ns:Keywords>
          <ns:Keyword>[…]</ns:Keyword>
        </ns:Keywords>
      </ns:Item>
    </ns:Items>
  </ns:Response>
</ns:Content>

当然还有我用来读取文件的代码。这是我首先下载的文件，它作为 Object o 进入方法。我认为错误就在这里某处，因为 XML 使用在线工具验证此模式...为了便于阅读，我删除了 try-catch block 。

main method {
    File file = (File) o;
    DocumentBuilderFactory f = DocumentBuilderFactory.newInstance();

    DocumentBuilder b = f.newDocumentBuilder();
    Document doc = b.parse(file.getAbsolutePath());
    doc.getDocumentElement().normalize();


    // Add the correct namespace to the xml so there won't be any false positive errors
    // Got this part from SO
    Element originalDocumentElement = doc.getDocumentElement();
    Element newDocumentElement = doc.createElementNS(NAMESPACE, originalDocumentElement.getNodeName());
    newDocumentElement.setPrefix("ns");
    NodeList list = originalDocumentElement.getChildNodes();
    while(list.getLength()!=0) {
        newDocumentElement.appendChild(list.item(0));
    }
    // Replace the original element
    doc.replaceChild(newDocumentElement, originalDocumentElement);

    xmlOptions = createXmlOptions();
    xmlDoc = XmlObject.Factory.parse(doc, xmlOptions);
    validate();
}
public XmlOptions createXmlOptions()
{
    Map<String, String> substituteNamespaces = new HashMap<String, String>();
    substituteNamespaces.put("", "http://namespace");
    XmlOptions xmlOptions = new XmlOptions();
    xmlOptions.setLoadSubstituteNamespaces(substituteNamespaces);
    xmlOptions.setCharacterEncoding(FILE_ENCODING);
    xmlOptions.setErrorListener(errors);
    xmlOptions.setValidateTreatLaxAsSkip();
    return xmlOptions;
}

public boolean validate() throws ParserException {

    return xmlDoc.validate(xmlOptions);
}

错误信息:error: cvc-elt.1: Invalid type

打印 error.getCursorLocation().xmlText() 返回整个 XML 文件。

架构用于命名空间

targetNamespace="http://red.persgroep.be/technology/1.0"

它对命名空间中的文档无话可说

xmlns:ns="http://namespace"

您只能根据适用于元素命名空间的模式验证元素。
