使用DOM解析器进行XML解析

在我的应用程序中，我试图使用DOM解析器解析XML文件。如果解析成功，那么该文件将被移动到成功目录，否则将出现错误directory.next从源目录中删除文件使用DOM解析器进行XML解析

问题是，当有一些生病的XML文件（例如：Xml文档缺少结束标记）异常随着以下错误消息一起抛出。

“，因为它正由另一个进程使用该进程无法访问文件。”

由于这个文件不是从源目录中删除。

public class XMLLoader extends Thread { 
boolean success =false; 
public XMLLoader(SoapConnection con, String xmlPath) { 

    try { 
     System.out.println("Laoding the XML..."); 
     File file = new File(xmlPath); 
     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
     DocumentBuilder builder = factory.newDocumentBuilder(); 
     Document document = builder.parse(file); 
     String xmlString = null; 

     DOMSource domSource = new DOMSource(document); 
     StringWriter writer = new StringWriter(); 
     StreamResult result = new StreamResult(writer); 
     TransformerFactory tf = TransformerFactory.newInstance(); 
     Transformer transformer = tf.newTransformer(); 
     transformer.transform(domSource, result); 
     xmlString = writer.toString(); 
     InboundCaseXmlResponse cResponse = con.LoadXmlCase(xmlString); 
     System.out.println("SOAP Response == "+cResponse); 
     if(cResponse.getHasErrors()== false) 
     { 
      success = true; 
     } 


    } catch (Exception e) { 
     System.out.println(e.getMessage()); 

     } 


} 
public boolean getStatus() 
{ 
    return success; 
}

}

您需要捕获异常，并在发现你需要移动XML错误的文件夹。更新有问题的代码。 – vels4j

您还没有指定任何语言或特定的技术，因此我们所能做的只是猜测。在特殊情况下，很可能没有及时清理某些东西。例如，如果您的语言支持它们，则可以通过明智地使用'finally'块或'using'子句来解决这个问题。 –

hi vels4j，我用代码更新了这个问题。感谢 –

我刚刚发现一个笑着的方式..

private static boolean loadXml(SoapConnection con, String xmlPath) { 
    boolean success =false; 
    FileInputStream file=null; 
    try { 
     System.out.println("Loading the XML..."); 
     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
     DocumentBuilder builder = factory.newDocumentBuilder(); 
     file = new FileInputStream(xmlPath); 
     Document document = builder.parse(file); 
     System.out.println(document.hasChildNodes()); 
     String xmlString = null;    
     DOMSource domSource = new DOMSource(document); 
     StringWriter writer = new StringWriter(); 
     StreamResult result = new StreamResult(writer); 
     TransformerFactory tf = TransformerFactory.newInstance(); 
     Transformer transformer = tf.newTransformer(); 
     transformer.transform(domSource, result); 
     xmlString = writer.toString(); 
     InboundCaseXmlResponse cResponse = con.LoadXmlCase(xmlString); 
     System.out.println("SOAP Response == "+cResponse); 
     if(cResponse.getHasErrors()== false) 
     { 
      success = true; 
     } 
     } catch (Exception e) { 
     System.out.println(e.getMessage()); 
     try{ 
     file.close(); 
     } 
     catch(Exception ex) 
     { 
     e.printStackTrace();  
     } 

     } 

    return success; 
}
