How to convert xml to json

The steps to convert XML to JSON are as follows: 1. Parses XML data and creates an XML tree structure. 2. Create an empty JSON object. 3. Recursively traverse the XML tree and create corresponding JSON attributes for each node. 4. Process nested elements and create nested JSON objects. 5. Format JSON data using the JSON parser.

How to convert XML to JSON

Converting XML to JSON involves the following main steps:

1. Parsing XML data

Use a suitable XML parser, such as xml.etree.ElementTree in Python, to parse XML data and create a tree structure representing an XML document.

2. Create a JSON object

Create an empty JSON object as a container representing the converted JSON data.

3. Recursively traverse the XML tree

Perform recursive traversal of each node in the XML tree and perform the following steps:

• Element: For element nodes, create a new attribute for the JSON object with the element name as the key and take the element value as the value.
• Attribute: For attribute nodes, add the attribute name as key and the attribute value as value to the JSON object.
• Text: For text nodes, add text values ​​as values ​​to the JSON object.
• Child elements: If there are child elements, create a nested JSON object and recursively traverse the subtree.

4. Handle nested elements

Adds a recursively created nested JSON object as a value to the JSON object, with the key being the name of the nested element.

5. Format JSON data

Use a JSON parser such as json in Python to convert a JSON object to a formatted JSON string.

Example:

 <code># Python 示例import xml.etree.ElementTree as ET import json # 解析XML root = ET.parse('example.xml').getroot() # 创建JSON 对象json_data = {} # 递归遍历XML 树def convert_to_json(node): for child in node: if child.tag in json_data: json_data[child.tag].append(convert_to_json(child)) else: json_data[child.tag] = [convert_to_json(child)] if child.attrib: json_data[child.tag].extend([{k: v} for k, v in child.attrib.items()]) if child.text: json_data[child.tag].append(child.text) return json_data # 转换根元素为JSON json_data = convert_to_json(root) # 格式化JSON 数据json_string = json.dumps(json_data, indent=4) # 打印JSON 数据print(json_string)</code>
