# Use create_document_using_DOM if create_document_using_parser throws an exception
# due to unsupported type 'text/html' (Firefox < 12, Opera)

# Use create_document_using_write if:
# - DOMParser isn't defined
# - create_document_using_parser returns null due to unsupported type 'text/html' (Chrome, Safari)
# - create_document_using_DOM doesn't create a valid HTML document (safeguarding against potential edge cases)
