Python Ansible Jinja2 map (属性)带有特殊字符

我正在构建一组Anable任务，使用它们的API通过Namecheap续订HTTPS证书.他们的API返回XML响应，所以我一直在使用Ansible Community ity.General al.xml模块来解析我从每个响应中需要的内容.其中一项任务是连接每个中间证书以构建证书链文件，但Ansible模块返回的属性名包括特殊字符以指示XML名称空间.

以下是来自Namecheap API端点的示例响应.我正在try 获取三个<Certificate> node ，每个 node 都在其自己的<Certificate Type="INTERMEDIATE"> node 内.

<?xml version="1.0" encoding="UTF-8"?>

                        <Certificate Type="INTERMEDIATE">

</ApiResponse>

这是我目前正在处理的一组可分析任务的"基线".

- name: parse info response for cert chain
  community.general.xml:
    xmlstring: "{{ namecheap_info.content }}"
    namespaces:
      x: 'http://api.namecheap.com/xml.response'
    xpath: '/x:ApiResponse/x:CommandResponse/x:SSLGetInfoResult/x:CertificateDetails/x:Certificates/x:CaCertificates/x:Certificate/x:Certificate'
    content: text
  register: parsed_cert_chain

- ansible.builtin.set_fact:
    namecheap_cert_chain_content: "{{ parsed_cert_chain.matches | map(attribute='{http://api.namecheap.com/xml.response}Certificate') }}"

当我运行这些任务时，我从ansible.Builtin.set_act模块得到一个错误:The task includes an option with an undefined variable. The error was: 'dict object' has no attribute '{http://api'..我知道这是因为URL中的句点被视为属性访问器，但我还没有成功地弄清楚如何转义它.

以下是我try 过的一些方法(请注意，其中一些只是在黑暗中拍摄)及其各自的错误消息:

• 在句点('dict object' has no attribute '{http://api\\\\'.)上使用反斜杠
• 句点上的双反斜杠('dict object' has no attribute '{http://api\\\\\\\\'.)
• 大括号上的反斜杠('dict object' has no attribute '\\\\{http://api'.)
• 使用方括号将字符串括起来(请参见https://stackoverflow.com/a/55223203)(dict object has no element ['{http://api.namecheap.com/xml.response}Certificate'].)
• try 字符串内侧的方括号('dict object' has no attribute '[{http://api'.)

我想我可以在将字符串传递到XML模块之前使用替换过滤器从字符串中删除XML名称空间，但这感觉有点像创可贴.转义map(attribute)JJAA2过滤器的特殊字符的正确方法是什么？
