Examples

Basic XML Conversion

Converting a simple XML document to JSON

Input:

<?xml version="1.0"?>
<person>
  <name>Jane Smith</name>
  <age>25</age>
  <email>[email protected]</email>
</person>

Output:

{
  "person": {
    "name": "Jane Smith",
    "age": 25,
    "email": "[email protected]"
  }
}

Attributes and Nested Elements

Handling XML attributes and nested structure

Input:

<?xml version="1.0"?>
<order id="123" date="2024-01-15">
  <customer type="regular">
    <name>Bob Wilson</name>
    <contact>
      <phone>555-0123</phone>
      <email>[email protected]</email>
    </contact>
  </customer>
</order>

Output:

{
  "order": {
    "_attributes": {
      "id": "123",
      "date": "2024-01-15"
    },
    "customer": {
      "_attributes": {
        "type": "regular"
      },
      "name": "Bob Wilson",
