How can I convert JSON to XML in Ruby?

Question

Is there any way to convert JSON to XML in Ruby?

Answer 1

The other answers do not allow for simple recursive conversions. As explained in this answer on Code Review, you'll need a custom helper to create the simple format you're looking for.

It will turn this...

data = [
  { 'name' => 'category1',
    'subCategory' => [
      { 'name' => 'subCategory1',
        'product' => [
          { 'name' => 'productName1',
            'desc' => 'desc1' },
          { 'name' => 'productName2',
            'desc' => 'desc2' } ]
      } ]
  },
  { 'name' => 'category2',
    'subCategory' => [
      { 'name' => 'subCategory2.1',
        'product' => [
          { 'name' => 'productName2.1.1',
            'desc' => 'desc1' },
          { 'name' => 'productName2.1.2',
            'desc' => 'desc2' } ]
      } ]
  },
]

...into this:

  
    category1
    
      subCategory1
      
        productName1
        desc1
      
      
        productName2
        desc2
      
    
  
  
    category2
    
      subCategory2.1
      
        productName2.1.1
        desc1
      
      
        productName2.1.2
        desc2
