① java 如何解析由String类型拼接的XML格式

public static void main(String[] args) throws DocumentException {
String xml="<?xml version= '1.0' encoding='gb2312'?><weighData><weighTime>2012-12-2 12:23:12</weighTime><cardNum>2</cardNum><cfid>123</cfid></weighData>";
Document dom=DocumentHelper.parseText(xml);
Element root=dom.getRootElement();
String weighTime=root.element("weighTime").getText();
String cardNum=root.element("cardNum").getText();
String cfid=root.element("cfid").getText();
System.out.println(weighTime);
System.out.println(cardNum);
System.out.println(cfid);
}
//需要的包 dom4j.jar

② Java中用string拼接成xml

不建议对string拼接xml串容易出错，java 有很多bean转xml的工具，这样容易很多，也不容易出错，JAXB 是不错的选择，j2ee中自带了，或者从搜索引擎中找 ，代码参考，一个TRequest 类，他有几个属性 name,id等等
@XmlRootElement(name = "TRequest")
@XmlAccessorType(XmlAccessType.FIELD)
public class TRequest implements java.io.Serializable{

@XmlElement(name="name")
private String name;
@XmlElement(name="id")
private String id;
public String getName() {
return name;
}
public void setId(String id) {
this.id = id;
}
public String getId() {
return id;
}
public void setName(String name) {
this.name = name;
}
}

TRequest t= new TRequest();
t.setName("ddddddd");
t.setId("11");
StringWriter writer = new StringWriter();
JAXBContext context = JAXBContext.newInstance(t.getClass());
Marshaller marshaller = context.createMarshaller();
// marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE);
marshaller.marshal(t, writer);
String res=writer.toString();
writer.close();

③ 用Java怎么把String类型的字符串转化为XML格式输出

java中将string转换成xml文件，使用开源jar包 dom4j：

packagecom.webdesk.swing.powertable.util;

importjava.io.ByteArrayInputStream;
importjava.io.File;
importjava.io.FileWriter;
importjava.io.IOException;

importorg.dom4j.Document;
importorg.dom4j.DocumentException;
importorg.dom4j.io.OutputFormat;
importorg.dom4j.io.SAXReader;
importorg.dom4j.io.XMLWriter;

publicclassXmlUtil{

(StringfileName){
try{
SAXReadersaxReader=newSAXReader();//新建一个解析类
DocumenttempDocument=saxReader.read(XmlUtil.class.getClassLoader().getResourceAsStream(fileName));//读入一个文件
returntempDocument.asXML();
}catch(DocumentExceptione){
e.printStackTrace();
}
returnnull;
}
//将字符串类型转换成xml文件
publicstaticvoidstrChangeXML(Stringstr)throwsIOException{
SAXReadersaxReader=newSAXReader();
Documentdocument;
try{
document=saxReader.read(newByteArrayInputStream(str.getBytes("UTF-8")));
OutputFormatformat=OutputFormat.createPrettyPrint();
/**将document中的内容写入文件中*/
XMLWriterwriter=newXMLWriter(newFileWriter(newFile("src/com/webdesk/swing/powertable/digester/cctv.xml")),format);
writer.write(document);
writer.close();
}catch(DocumentExceptione){
e.printStackTrace();
}

}
}

④ java String类型，转化为XML形式的String类型。

importjava.lang.reflect.Field;
importjava.lang.reflect.Method;

importorg.dom4j.Document;
importorg.dom4j.DocumentHelper;
importorg.dom4j.Element;

{
	
	privateStringx="xxxx";
	privateStringy="yyyy";
	privateAa;
	
	publicstaticvoidmain(String[]args){
		BuildXmlFromPropertiest=newBuildXmlFromProperties();
		Aa=newA("aXxxxx","aYyyyy");
		Bb=newB("abXxxx","abYyyy");
		a.setB(b);
		t.setA(a);
		
		Documentdoc=DocumentHelper.createDocument();
		ElementbeginEle=doc.addElement("begin");
		ElementstartEle=beginEle.addElement("start");
		t.buildElement(t,"first",startEle);
		System.out.println(doc.asXML());
	}

	publicvoidbuildElement(Objectobj,Stringtitle,ElementparentElement){
		if(obj.getClass().getName().equals("java.lang.String")){
			parentElement.addElement(title).setText(obj+"");
			
		}else{
			ElementsubElement=parentElement.addElement(title);
			Field[]fields=obj.getClass().getDeclaredFields();
			for(inti=0;i<fields.length;i++){
				Methodmethod=null;
				ObjectsubObj=null;
				StringsubTitle=fields[i].getName();
				try{
					StringmethodName="get"+subTitle.substring(0,1).toUpperCase()+(subTitle.length()==1?"":subTitle.substring(1));
					method=obj.getClass().getDeclaredMethod(methodName,null);
					subObj=method.invoke(obj,null);
				}catch(Exceptione){
					
					e.printStackTrace();
					
				}
				buildElement(subObj,subTitle,subElement);
			}
		}
	}

	publicStringgetX(){
		returnx;
	}

	publicStringgetY(){
		returny;
	}

	publicAgetA(){
		returna;
	}

	publicvoidsetX(Stringx){
		this.x=x;
	}

	publicvoidsetY(Stringy){
		this.y=y;
	}

	publicvoidsetA(Aa){
		this.a=a;
	}
}classA{
	privateStringaX;
	privateStringaY;
	privateBb;
	
	publicA(StringaX,StringaY){
		this.aX=aX;
		this.aY=aY;
	}
	publicStringgetAX(){
		returnaX;
	}
	publicStringgetAY(){
		returnaY;
	}
	publicvoidsetAX(StringaX){
		this.aX=aX;
	}
	publicvoidsetAY(StringaY){
		this.aY=aY;
	}
	publicBgetB(){
		returnb;
	}
	publicvoidsetB(Bb){
		this.b=b;
	}
}

classB{
	privateStringabX;
	privateStringabY;
	publicB(StringabX,StringabY){
		this.abX=abX;
		this.abY=abY;
	}
	
	publicStringgetAbX(){
		returnabX;
	}
	publicStringgetAbY(){
		returnabY;
	}
	publicvoidsetAbX(StringabX){
		this.abX=abX;
	}
	publicvoidsetAbY(StringabY){
		this.abY=abY;
	}
}

主要就是用了递归，然后反射取字段的名字和值

⑤ java 、String、xml。我有一个字符创是String型的，如何向xml格式那样保存，具体如下：

用document创建XML

⑥ 怎么在java代码中获取string.xml中的字符串

<string name="wait">等待</string>
在String.xml定义了这个一个字符串，在代码中调用：
textview.setText（R.string.wait）；

⑦ java如何把String转换成xml

二种方式：
1、直接拼接字符串，如下
StringBuffer xml = new StringBuffer();
xml.append("<xml>");
xml.append("\r\n");
Iterator<Map.Entry<String, String>> entries = jovalue.entrySet().iterator();
while (entries.hasNext()) {
Map.Entry<String, String> entry = entries.next();
xml.append("<"+entry.getKey()+">");
xml.append(entry.getValue());
xml.append("</"+entry.getKey()+">");
xml.append("\r\n");
}
xml.append("</xml>");
return xml.toString();
用第三方包：dom4j-1.6.1.jar，示例如下
Document document = DocumentHelper.createDocument();
Element xml = document.addElement("xml");
Iterator<Map.Entry<String, String>> entries = jovalue.entrySet().iterator();
while (entries.hasNext()) {
Map.Entry<String, String> entry = entries.next();
Element xml_sub = xml.addElement(entry.getKey());
xml_sub.setText(entry.getValue());
}
return document.asXML();

⑧ java截取XML字符串

读取之后用正则截取

@"<[^?][\s\S]*"

⑨ 如何在java代码中获取string.xml中的字符串

获取string.xml文件里面的值有几个不同的地方。

1.在AndroidManifest.xml与layout等xml文件里:

android:text="@string/resource_name"

2.在activity里：

方法一:this.getString(R.string.resource_name);

方法二:getResources().getString(R.string.resource_name);

3.在其他java文件（必须有Context或pplication）

方法一:
context.getString(R.string.resource_name);
方法二: application.getString(R.string.resource_name);

⑩ java 字符串组合成xml

输出的时候加个格式！！！
String xml = “你的专xml”;
HttpServletResponse response = ServletActionContext.getResponse();
response.setCharacterEncoding("utf-8");
response.setContentType("text/xml;charset=UTF-8");//这里注意是属xml
response.setHeader("Cache-Control", "no-cache");
response.getWriter().print(xml);
