dom4j删除XML声明

[williamxiao]

需求是这样的:需要将两个使用DOM4J生成的XML文件合成一个,详细如下:

有两个生成XML文件的方法,生方方法和生成的XML如下:
CreateXML1.java:

         /**
	 * 将结果集构建成XML字符串
	 * @param lst 结果集
	 * @return XML字符串
	 */
	private String createXML(List lst)
	{
		if(lst==null||lst.size()<1)
			return null;
		// 获得dom4j xml文档对象
		Document document = DocumentHelper.createDocument();
		//创建dom4j xml根节点
		Element root = document.addElement("hhsClientHealths");		
		//遍历list向根节点添加子元素
		for (Iterator iterator = lst.iterator(); iterator.hasNext();)
		{
			HhsClientHealth hhsClientHealth = (HhsClientHealth) iterator.next();
			Element element = root.addElement("hhsClientHealth");
			element.addElement("chlthId").addText(hhsClientHealth.getChlthId());
			element.addElement("clntId").addText(hhsClientHealth.getClntId());
			element.addElement("clntName").addText(hhsClientHealth.getClntName());
			element.addElement("blodtpId").addText(hhsClientHealth.getBlodtpId());
			element.addElement("blodtpName").addText(hhsClientHealth.getBlodtpName());
			element.addElement("hospId").addText(hhsClientHealth.getHospId());
			element.addElement("hospName").addText(hhsClientHealth.getHospName());
			element.addElement("chlthStatare").addText(hhsClientHealth.getChlthStatare().toString());
			element.addElement("chlthWeight").addText(hhsClientHealth.getChlthWeight().toString());
			element.addElement("chlthIllHistory").addText(hhsClientHealth.getChlthIllHistory());
			element.addElement("chlthIrriHistory").addText(hhsClientHealth.getChlthIrriHistory());			
		}		
		//将XML输出到字符串		
		return document.asXML();
	}

xml1.xml:

<?xml version="1.0" encoding="UTF-8" ?> 
<hhsClientHealths>
  <hhsClientHealth>
  <chlthId>1</chlthId> 
  <clntId>1001</clntId> 
  <clntName>李先生</clntName> 
  <blodtpId>1</blodtpId> 
  <blodtpName>A</blodtpName> 
  <hospId>1</hospId> 
  <hospName>附二院</hospName> 
  <chlthStatare>170.0</chlthStatare> 
  <chlthWeight>100.2</chlthWeight> 
  <chlthIllHistory>无</chlthIllHistory> 
  <chlthIrriHistory>无</chlthIrriHistory> 
  </hhsClientHealth>
</hhsClientHealths>

CreateXML2.java:

         /**
	 * 将结果集构建成XML字符串
	 * @param lst 结果集
	 * @return XML字符串
	 */
	private String createXML(List lst)
	{
		if(lst==null||lst.size()<1)
			return null;
		// 获得dom4j xml文档对象
		Document document = DocumentHelper.createDocument();
		//创建dom4j xml根节点
		Element root = document.addElement("bloodTypes");		
		//遍历list向根节点添加子元素
		for (Iterator iterator = lst.iterator(); iterator.hasNext();)
		{
			BloodType bloodType = (BloodType) iterator.next();
			Element element = root.addElement("bloodType");
			element.addElement("blodtpId").addText(bloodType.getBlodtpId());
			element.addElement("blodtpName").addText(bloodType.getBlodtpName());
		}
		//将XML输出到字符串		
		return document.asXML();
	}

xml2.xml:

<?xml version="1.0" encoding="UTF-8" ?> 
<bloodTypes>
  <bloodType>
  <blodtpId>1</blodtpId> 
  <blodtpName>A</blodtpName> 
  </bloodType>
  <bloodType>
  <blodtpId>2</blodtpId> 
  <blodtpName>B</blodtpName> 
  </bloodType>
  <bloodType>
  <blodtpId>3</blodtpId> 
  <blodtpName>O</blodtpName> 
  </bloodType>
  <bloodType>
  <blodtpId>4</blodtpId> 
  <blodtpName>AB</blodtpName> 
  </bloodType>
</bloodTypes>

现在想要得到下面这样的XML:
want.xml:

<?xml version="1.0" encoding="UTF-8" ?> 
<hhsClientHealths>
  <hhsClientHealth>
  <chlthId>1</chlthId> 
  <clntId>1001</clntId> 
  <clntName>李先生</clntName> 
  <blodtpId>1</blodtpId> 
  <blodtpName>A</blodtpName> 
  <hospId>1</hospId> 
  <hospName>附二院</hospName> 
  <chlthStatare>170.0</chlthStatare> 
  <chlthWeight>100.2</chlthWeight> 
  <chlthIllHistory>无</chlthIllHistory> 
  <chlthIrriHistory>无</chlthIrriHistory> 
  </hhsClientHealth>  
  <bloodTypes>
    <bloodType>
    <blodtpId>1</blodtpId> 
    <blodtpName>A</blodtpName> 
    </bloodType>
    <bloodType>
    <blodtpId>2</blodtpId> 
    <blodtpName>B</blodtpName> 
    </bloodType>
    <bloodType>
    <blodtpId>3</blodtpId> 
    <blodtpName>O</blodtpName> 
    </bloodType>
    <bloodType>
    <blodtpId>4</blodtpId> 
    <blodtpName>AB</blodtpName> 
    </bloodType>
  </bloodTypes>
</hhsClientHealths>

主要想结合这两类的方法来生成一个XML,不知各位有没有什么方法可以做.

package org.aninggo.code.material.sessionfactory;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentFactory;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;

public class T {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Document d1 = null;
		Document d2 = null;
		Document d3 = null;
		XMLWriter writer = null;
		OutputFormat format = OutputFormat.createPrettyPrint();
		try {
			d1 = new SAXReader().read(new File("D:\\x1.xml"));
			d2 = new SAXReader().read(new File("D:\\x2.xml"));
			d3 = DocumentFactory.getInstance().createDocument(DocumentFactory.getInstance().createElement("root"));
			d3.getRootElement().add(d1.getRootElement());
			d3.getRootElement().add(d2.getRootElement());
			writer = new XMLWriter(new FileWriter("D:\\x3.xml"), format);
			writer.write(d3);
		} catch (DocumentException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			if(writer != null) {
				try {
					writer.flush();
					writer.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
				writer = null;
			}
		}
	}

}

Sorry,这不一样,只能生成这样的文件:和需求不符
<?xml version="1.0" encoding="UTF-8"?>

<root>
<hhsClientHealths>
<hhsClientHealth>
<chlthId>1</chlthId>
<clntId>1001</clntId>
<clntName>李先生</clntName>
<blodtpId>1</blodtpId>
<blodtpName>A</blodtpName>
<hospId>1</hospId>
<hospName>附二院</hospName>
<chlthStatare>170.0</chlthStatare>
<chlthWeight>100.2</chlthWeight>
<chlthIllHistory>无</chlthIllHistory>
<chlthIrriHistory>无</chlthIrriHistory>
</hhsClientHealth>
</hhsClientHealths>
<bloodTypes>
<bloodType>
<blodtpId>1</blodtpId>
<blodtpName>A</blodtpName>
</bloodType>
<bloodType>
<blodtpId>2</blodtpId>
<blodtpName>B</blodtpName>
</bloodType>
<bloodType>
<blodtpId>3</blodtpId>
<blodtpName>O</blodtpName>
</bloodType>
<bloodType>
<blodtpId>4</blodtpId>
<blodtpName>AB</blodtpName>
</bloodType>
</bloodTypes>
</root>
