Open Peoolの電子インボイスデータは、電子商取引のメッセージ標準である UBL を使用しています。 サンプルの電子インボイスを作成するためのツールをPythonで開発した。
以下は、次のGitHubで公開している genInvoice の解説。
https://github.com/pontsoleil/EIPA/tree/master/pint_ja
Pythonでは、XML文書を作成するライブラリ、xml.etree.ElementTreeを使用。
Excelで電子インボイスのデータを作成し、TSV形式（タブ区切り）で出力したファイルから、UBLの電子インボイスを作成する。
標準ではShift JIS出力されてしまい、ElementTreeでエラーとなるので、一旦テキストエディターで開いて、UTF-8に変換登録したものを入力ファイルとする。
TSVからUBLの電子インボイスを作成するプログラム genInvoice 及びUBLの電子インボイスをTSVに変換するプログラム invoice2tsv を作成した。
サンプル電子インボイス
CEFが公開している電子インボイスのGitHubからのサンプル電子インボイスを使用して検証します。

ElementTreeのfromstring()で読み込み、tostring()で出力
Pythonプログラム
print(ET.tostring(root).decode()) で出力すると名前空間のコードがcac:からns3:等に変わってしまう。
import xml.etree.ElementTree as ET
