XML和JSON数据格式简介** XML(可扩展标记语言)和JSON(JavaScript对象表示法)是两种广泛用于数据表示和交换的流行数据格式。XML基于树形结构,使用标签和属性来组织数据,而JSON基于键值对,采用轻量级文本格式。 XML具有良好的可读性和可扩展性,常用于结构化数据,如文档、配置和数据交换。JSON则以其轻量、易于解析和处理的特点著称,广泛应用于Web服务和移动应用程序中。 # 2. XML和JSON数据转换技术 ### 2.1 XML到JSON转换 #### 2.1.1 在线转换工具 **XML to JSON Converter** - **网址:** https://www.convertxml.com/ - **特点:** - 支持多种XML和JSON格式 - 提供高级选项,如转换规则和数据类型映射 - **使用步骤:** 1. 上传或粘贴XML数据 2. 选择输出格式为JSON 3. 点击“转换”按钮 **XML2JSON** - **网址:** https://xml2json.io/ - **特点:** - 简单的界面,易于使用 - 支持XML和JSON的多种变体 - **使用步骤:** 1. 输入XML数据 2. 选择输出格式为JSON 3. 点击“转换”按钮 #### 2.1.2 代码转换方法 **Python** ```python import xmltodict xml_data = """ <root> <name>John Doe</name> <age>30</age> </root> json_data = xmltodict.parse(xml_data) print(json.dumps(json_data)) ``` **逻辑分析:** - `xmltodict.parse()`函数将XML数据解析为Python字典。 - `json.dumps()`函数将Python字典转换为JSON字符串。 **参数说明:** - `xml_data`:要转换的XML数据。 - `json_data`:转换后的JSON数据。 **Java** ```java import javax.xml.bind.JAXBContext; import javax.xml.bind.Marshaller; import javax.xml.bind.Unmarshaller; public class XmlToJsonConverter { public static void main(String[] args) throws Exception { JAXBContext jaxbContext = JAXBContext.newInstance(Employee.class); Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); Employee employee = (Employee) unmarshaller.unmarshal(new File("employee.xml")); Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.marshal(employee, new File("employee.json")); } public static class Employee { private String name; private int age; // 省略其他属性和方法 } } ``` **逻辑分析:** - 使用JAXB(Java Architecture for XML Binding)将XML数据绑定到Java对象。 - 使用`Unmarshaller`将XML数据解组为Java对象。 - 使用`Marshaller`将Java对象编组为JSON数据。 **参数说明:** - `employee.xml`:要转换的XML文件。 - `employee.json`:转换后的JSON文件。 - `Employee`类:用于绑定XML数据的Java类。 ### 2.2 JSON到XML转换 #### 2.2.1 在线转换工具 **JSON to XML Converter** - **网址:** https://www.convertjson.com/ - **特点:** - 支持多种JSON和XML格式 - 提供高级选项,如转换规则和数据类型映射 - **使用步骤:** 1. 上传或粘贴JSON数据 2. 选择输出格式为XML 3. 点击“转换”按钮 **JSON2XML** - **网址:** https://json2xml.io/ - **特点:** - 简单的界面,易于使用 - 支持JSON和XML的多种变体 - **使用步骤:** 1. 输入JSON数据 2. 选择输出格式为XML 3. 点击“转换”按钮 #### 2.2.2 代码转换方法 **Python** ```python import json from xml.etree.ElementTree import Element, SubElement, tostring json_data = """ { "name": "John Doe", "age": 30 } root = Element("root") name = SubElement(root, "name") name.text = json_data["name"] age = SubElement(root, "age") age.text = str ```
