A sample code on how to use lxml library to generate an xml file. Example of data, it is a list of dictionary

[
   {
      'tag': 'tag_name', 'value': 'value', 'attrs': {
          'attribute1': 'attribute1', 'attribute2': 'attribute2'
          },
          'nsmap': {'ns1': 'ns1', 'ns2': 'ns2'}
   },
   {
      'tag': 'another_tag', 'value': [{'tag': 'another_tag_c', 'value': 'value1'}]
   }
]

1. tag is the tag name (h1)
2. value is the value of the tag
3. attrs contain a dictionary of the tag's attributes
4. nsmap contain a dictionary of the tag's namespaces

This is the output (the content of the output.xml file) when you execute the example.py file.

<RootElement>
  <tag_name xmlns:ns1="ns1" xmlns:ns2="ns2" attribute1="attribute1" attribute2="attribute2">value</tag_name>
  <another_tag>
    <another_tag_c>value1</another_tag_c>
  </another_tag>
</RootElement>
