javaxmltojson

Ⅰ java實現復雜的 xml 轉化為 JSON

提供一種方案：xml通過jaxb轉換成java對象，
然後java對象再轉換為json, 都有現成的框架。

Ⅱ 在java中怎麼把xml文件轉換成json格式

在java中把xml文件轉換成json格式
1、前提需要jar包：
json-lib-2.4-jdk15.jar 和 xom-1.2.5.jar ，maven 倉庫：
net.sf.json-lib
json-lib
2.4
jdk15

xom
xom
1.2.5

2、代碼部分：
public static JSON xmlToJson(String xml) {
XMLSerializer xmlSerializer = new XMLSerializer();
if(xml!=null && !」「.equals(xml)){
xml = xml.replaceAll(「\r|\n」, 「」);
JSON json = xmlSerializer.read(xml);
return json;
}else{
return null;
}

}
public static void main(String[] args) {
String xmlStr = "<parent><id>01</id<name>marry</name</parent>";
JSON json = xmlToJson(xmlStr);
System.out.println(json.toString());

}
3、結果：
{「id」:」01」,」name」:」marry」}

Ⅲ JAVA能把下面的 xml 轉化為JSON

}
}需要的jar
需要json-lib-2.1-jdk15.jar和xom-1.2.5.jar，maven pom.xml如下：

Ⅳ java 用XMLSerializer處理xml轉json時，xml節點的屬性在轉為json後，屬性上為有@符號，怎麼處理掉@。

@要用replace替換成-減號符，這樣在json字元串中能代表屬性

Ⅳ javascript 將xml轉換為json對象

代碼如下:

//ChangesXMLtoJSON
functionxmlToJson(xml){
//Createthereturnobject
varobj={};
if(xml.nodeType==1){//element
//doattributes
if(xml.attributes.length>0){
obj["@attributes"]={};
for(varj=0;j<xml.attributes.length;j++){
varattribute=xml.attributes.item(j);
obj["@attributes"][attribute.nodeName]=attribute.nodeValue;
}
}
}elseif(xml.nodeType==3){//text
obj=xml.nodeValue;
}
//dochildren
if(xml.hasChildNodes()){
for(vari=0;i<xml.childNodes.length;i++){
varitem=xml.childNodes.item(i);
varnodeName=item.nodeName;
if(typeof(obj[nodeName])=="undefined"){
obj[nodeName]=xmlToJson(item);
}else{
if(typeof(obj[nodeName].length)=="undefined"){
varold=obj[nodeName];
obj[nodeName]=[];
obj[nodeName].push(old);
}
obj[nodeName].push(xmlToJson(item));
}
}
}
returnobj;
};
