的子元素发现了非法的文本数据

Question

我正在尝试将xml转换为Spring MVC 4中的对象。但是我得到了这个错误(只是其中的一部分):

Caused by: org.xml.sax.SAXException: Illegal Text data found as child of: comprobante
  value: "<?xml version="1.0" encoding="UTF-8"?> <comprobanteRetencion id="comprobante" version="1.0.0"> <infoTributaria> <ambiente>2</ambiente> <tipoEmision>1</tipoEmision> <razonSocial> ... (resto del XML)

这是我试图转换的一段xml(它太大了):

有人知道得到这个错误的原因吗?之前有人在stackoverflow上贴了这个问题，但是答案被删除了。

Answer 1

根据映射，comprobante元素应该有名为comprobanteRetencion的子元素，但是在您的输入XML文件中，comprobante元素包含文本。这就是Castor抱怨的原因

Answer 2

最后，我将xml转换为字符串。

private static String convertDocumentToString(Document doc) {
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer;
    try {
        transformer = tf.newTransformer();
        // below code to remove XML declaration
        // transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        StringWriter writer = new StringWriter();
        transformer.transform(new DOMSource(doc), new StreamResult(writer));
        String output = writer.getBuffer().toString();
        return output;
    } catch (TransformerException e) {
        e.printStackTrace();
    }
    return null;
}

之后，我通过替换它来删除CDATA标签:

    DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
    Document doc = docBuilder.parse(filePath);
    String text = convertDocumentToString(doc);
    String pattern = "<![CDATA[<?xml version=" + """ + "1.0" + """ + " encoding=" + """ + "UTF-8" + ""?>";
    text = text.replace(pattern, "");  
    text = text.replace("]]>", ""); 
    doc = convertStringToDocument(text);

最后，我使用以下方法将字符串转换回XML:

private static Document convertStringToDocument(String xmlStr) {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  
    DocumentBuilder builder;  
    try 
    {  
        builder = factory.newDocumentBuilder();  
        Document doc = builder.parse( new InputSource( new StringReader( xmlStr ) ) ); 
        return doc;
    } catch (Exception e) {  
        e.printStackTrace();  
    } 
    return null;
}
