Understanding Base64:

Before diving into the code, let’s briefly understand Base64 encoding. It’s a method to encode binary data, like images, into ASCII characters. Each character represents six bits of the original data, making it easily transferable via text protocols.

Section 1: Base64 File

To convert JSON to XML for a Base64-encoded file, you can use the following Python code:

import json import xml.etree.ElementTree as ET import base64

def json_to_xml(json_data): root = ET.Element(“root”) parse_json(root, json_data) return ET.tostring(root, encoding=“utf-8”, method=“xml”).decode()

def parse_json(parent, data): if isinstance(data, dict): for key, value in data.items(): child = ET.SubElement(parent, key) parse_json(child, value) elif isinstance(data, list): for item in data: parse_json(parent, item) else: parent.text = str(data)

def encode_base64_file(file_path): with open(file_path, “rb”) as file: encoded_data = base64.b64encode(file.read()).decode() return encoded_data

Example usage

file_path = “path/to/your/file.json” json_data = json.loads(base64.b64decode(encode_base64_file(file_path)).decode()) xml_result = json_to_xml(json_data) print(xml_result)

Section 2: Base64 Data as String

For converting JSON data passed as a Base64-encoded string:

import json import xml.etree.ElementTree as ET import base64

def json_to_xml(json_data): root = ET.Element(“root”) parse_json(root, json_data) return ET.tostring(root, encoding=“utf-8”, method=“xml”).decode()

def parse_json(parent, data): if isinstance(data, dict): for key, value in data.items(): child = ET.SubElement(parent, key) parse_json(child, value) elif isinstance(data, list): for item in data: parse_json(parent, item) else: parent.text = str(data)

def decode_base64_data(base64_string): decoded_data = base64.b64decode(base64_string).decode() return json.loads(decoded_data)

Example usage

base64_data = “your_base64_encoded_data_here” json_data = decode_base64_data(base64_data) xml_result = json_to_xml(json_data) print(xml_result)
