XMLSerializer & OutputFormat被否决

Question

我试图从S.O.周围的Java专家那里得到一些关于这个问题的帮助。我在一个很长的项目中偶然发现了一个XMLSerializer & OutputFormat的旧实现.我想知道是否有人能给出一个指示该做什么的指针，一个意见会非常感谢.

我试过这个aproach，但我无法用LSSerializer代替.

问题是..。

​

因此，基本上有人在项目中使用的类XMLSerializer & OutputFormat直接来自于internal .如何通过使用org.w3c将这种平静的代码转换为没有WAS ( Websphere Aplication )的依赖关系？

...
import org.apache.xml.serialize.OutputFormat;
import org.apache.xml.serialize.XMLSerializer;
import org.w3c.dom.DOMException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
...
public String toString() {
    StringWriter res = new StringWriter();
    OutputFormat format = new OutputFormat(doc);//doc is type org.w3c.dom.Document
    format.setIndenting(true);
    XMLSerializer serializer = new XMLSerializer(res, format);

    try {
        serializer.serialize(doc);
    } catch (IOException e) {
        res.write(e.getMessage());
        e.printStackTrace();
    }
    return res.toString();
}

后来，我设法用我提到的earlier...here来做这件事，它几乎是一个复制品.

...
import org.w3c.dom.DOMConfiguration;
import org.w3c.dom.DOMException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.w3c.dom.bootstrap.DOMImplementationRegistry;
import org.w3c.dom.ls.DOMImplementationLS;
import org.w3c.dom.ls.LSOutput;
import org.w3c.dom.ls.LSSerializer;
...

    public String toString() {
    StringWriter stringWriter = new StringWriter();
    String subscrXML=null;
    DOMImplementationRegistry registry = null;
    DOMImplementationLS impls = null;
    LSOutput domOutput = null;
    LSSerializer domWriter = null;
    try {

    registry =  DOMImplementationRegistry.newInstance();

    impls =  (DOMImplementationLS)registry.getDOMImplementation("LS");

     //Prepare the output
      domOutput = impls.createLSOutput();
      domOutput.setEncoding(java.nio.charset.Charset.defaultCharset().name());            
      domOutput.setCharacterStream(stringWriter);
      domOutput.setEncoding("UTF-8");

     //Prepare the serializer
      domWriter = impls.createLSSerializer();            
      DOMConfiguration domConfig = domWriter.getDomConfig();
      domConfig.setParameter("format-pretty-print", true);
      domConfig.setParameter("element-content-whitespace", true);
      domWriter.setNewLine("\r\n");     
      domConfig.setParameter("cdata-sections", Boolean.TRUE);

     //And finaly, write
      domWriter.write(doc, domOutput);
      subscrXML = domOutput.getCharacterStream().toString();
      //DOMStringList dsl=domConfig.getParameterNames();
        System.out.println(subscrXML);
        /*
         // Just for curiosity.... 
         for(int i=0;i<dsl.getLength();i){
            System.out.println(dsl.item(i)" = ["domConfig.getParameter(dsl.item(i))"]");
        }*/

    } catch (ClassCastException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InstantiationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }


    return subscrXML;
}

导入org.w3c.dom.ls.*并使用LLSSerializer！您还需要创建一个DOMImplementationLS来调用，这样就可以创建序列化程序。
