Python 標準モジュール (elementtree、lxml などは使用しない) を使用して xml ファイルを作成する必要があります。メタデータは SAML ID プロバイダーのメタデータであり、次の形式です。
<?xml version="1.0"?>

証明書の部分と少し混乱しています。オリジナルは<ds:X509Certificate>-----BEGIN CERTIFICATE---.....</ds:X509Certificate>
私のものです:
<ds:X509Certificate>
This is the cert
</ds:X509Certificate>
申し訳ありませんが、私は XML の経験があまりありません。コードは目的のタスクに適していますか。
ありがとう。
