Question

我想在python中解析xml以下。如果有任何错误，那么我想用描述代码和描述提取该信息

xml为NCPDP格式。我想从下面的xml中获取描述代码和描述。

<transport:Message StructuresVersion="2014041" ECLVersion="2014041" DatatypesVersion="2014041" TransactionDomain="SCRIPT" PA-StructuresVersion="2014041" TransactionVersion="2014041" TransportVersion="2014041" 
xsi:schemaLocation="http://www.ncpdp.org/schema/transport transport.xsd"

    </transport:SenderSoftware>
    <transport:TestMessage>1</transport:TestMessage>
</transport:Header>
<transport:Body>
    <transport:Error>
        <transport:Code>601</transport:Code>
        <transport:DescriptionCode>500</transport:DescriptionCode>
        <transport:Description>XML Validation Error: The 'http://www.ncpdp.org/schema/datatypes:Number' element is invalid - The value 'None' is invalid according to its datatype 'http://www.ncpdp.org/schema/datatypes:n1..10' - The Pattern constraint failed.</transport:Description>
    </transport:Error>
</transport:Body>

我在下面尝试过

import xml.etree.ElementTree as ET 
tree = ET.parse('parse.xml') 
root = tree.getroot() 
for child in root: 
    print(child.tag) 
    print("_______")

如果有任何错误，那么我想用说明代码和说明

这应该让您入门...

Python

import xml.etree.ElementTree as ET

tree = ET.parse('parse.xml')

ns = {"tr": "http://www.ncpdp.org/schema/transport"}

for error in tree.findall("./tr:Body/tr:Error", ns):
    print(f"ERROR CODE: {error.find('./tr:Code', ns).text}\n"
          f"ERROR DESCRIPTION: {error.find('./tr:Description', ns).text}")

输出

ERROR CODE: 601
ERROR DESCRIPTION: XML Validation Error: The 'http://www.ncpdp.org/schema/datatypes:Number' element is invalid - The value 'None' is invalid according to its datatype 'http://www.ncpdp.org/schema/datatypes:n1..10' - The Pattern constraint failed.
