xmljson

Warnings

• breaking The xmljson library is explicitly marked as not actively maintained, and its GitHub repository is archived, making it effectively abandoned. There will be no further updates, bug fixes, or compatibility assurances for this library. Users should consider migrating to actively maintained alternatives.
  Fix: Migrate to alternative libraries such as `xmltodict` or `untangle` for XML-to-JSON conversion.
• gotcha xmljson supports multiple XML-to-JSON conversion conventions (e.g., BadgerFish, GData, Parker). The choice of convention significantly alters the resulting JSON structure, particularly for attributes, text content, and nested elements. For example, BadgerFish prefixes attributes with `@` and text with `$`.
  Fix: Carefully review the documentation for each convention and select the one that best suits your desired JSON output format. Be prepared to transform the output further if no convention perfectly matches your needs.
• gotcha Converting XML to JSON can lead to inherent challenges due to structural differences (e.g., XML's attributes vs. JSON's key-value pairs, ordered XML elements vs. unordered JSON object properties, mixed content). This can result in data loss or non-intuitive JSON representations if not handled carefully. Mixed content is often represented using special keys like `$` or `#text`.
  Fix: Understand the limitations of automatic conversion. Validate the output JSON against your expectations. If complex XML structures like mixed content, namespaces, or varying cardinalities are present, manual post-processing of the generated JSON or using a library that offers more fine-grained control may be necessary.
• gotcha XML namespaces are not explicitly handled as a first-class feature across all conventions, which can be a significant issue when dealing with XML documents that heavily rely on namespaces. This might lead to unexpected keys or loss of namespace information in the JSON output.
  Fix: For XML with complex namespace requirements, it is crucial to test `xmljson`'s behavior with your specific documents and chosen convention. If it falls short, consider preprocessing the XML to remove or simplify namespaces, or use an alternative library with explicit namespace handling capabilities.

Quickstart

This quickstart demonstrates converting an XML string to a Python dictionary (which can then be serialized to JSON) and converting the dictionary back to an XML ElementTree object, using the BadgerFish convention. It highlights how attributes (e.g., 'value') are prefixed with '@' and text content with '$' in the resulting dictionary structure.

from xml.etree.ElementTree import fromstring, tostring
from xmljson import badgerfish as bf
import json

# Example XML string
xml_string = '<employees><person><name value="Alice"/></person><person><name value="Bob"/></person></employees>'

# Convert XML to a Python dictionary using BadgerFish convention
xml_element = fromstring(xml_string)
data_dict = bf.data(xml_element)
print('Python dict (BadgerFish):')
print(json.dumps(data_dict, indent=2))

# Convert Python dictionary back to XML
xml_from_dict = bf.etree(data_dict)
print('\nXML from dict (BadgerFish):')
print(tostring(xml_from_dict[0]).decode())
