Python: 如何将动态变量传递给XML？

Question

我正在使用 XMLs 的 USPS API。我希望能够将变量传递到 XML 树中，而不用 child 重建它 child。在 Python 中如何操作？

def fixed_xml_body_as_string(dest_zip, origin_zip):
  
  #pass zip codes into XML

  return """

  <RateV4Request USERID='XXXXXXXXXXX'>

  <Package ID="1ST">
  <Service>PRIORITY</Service>
  <ZipOrigination></ZipOrigination>
  <ZipDestination></ZipDestination>
  <Pounds>1</Pounds>
  <Ounces>0</Ounces>
  <Container></Container>
  <Width></Width>
  <Length></Length>
  <Height></Height>
  <Girth></Girth>
  <Machinable>false</Machinable>
  </Package>
  </RateV4Request>

我想将邮政编码动态传递到 XML。

只需使用如下所示的字符串格式（请注意，您的 'xml' 无效）

def fixed_xml_body_as_string(dest_zip, origin_zip):
    # pass zip codes into XML

    return f"""
  https://secure.shippingapis.com/shippingapi.dll?API=RateV4&XML=
  <RateV4Request USERID='XXXXXXXXXXX'>
  <Revision>2</Revision>
  <Package ID="1ST">
  <Service>PRIORITY</Service>
  <ZipOrigination>{origin_zip}</ZipOrigination>
  <ZipDestination>{dest_zip}</ZipDestination>
  <Pounds>1</Pounds>
  <Ounces>0</Ounces>
  <Container></Container>
  <Width></Width>
  <Length></Length>
  <Height></Height>
  <Girth></Girth>
  <Machinable>false</Machinable>
  </Package>
  </RateV4Request>
"""


print(fixed_xml_body_as_string(23, 99))

输出

 https://secure.shippingapis.com/shippingapi.dll?API=RateV4&XML=
  <RateV4Request USERID='XXXXXXXXXXX'>
  <Revision>2</Revision>
  <Package ID="1ST">
  <Service>PRIORITY</Service>
  <ZipOrigination>99</ZipOrigination>
  <ZipDestination>23</ZipDestination>
  <Pounds>1</Pounds>
  <Ounces>0</Ounces>
  <Container></Container>
  <Width></Width>
  <Length></Length>
  <Height></Height>
  <Girth></Girth>
  <Machinable>false</Machinable>
  </Package>
