在Python中验证XML订单

我有一个XML架构文件，该文件是为了示例的目的，我将使用 w3学校的一个如下：

    <?xml version="1.0"?>
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="https://www.w3schools.com" xmlns="https://www.w3schools.com" elementFormDefault="qualified">
    <xs:element name="note">
      <xs:complexType>
        <xs:sequence>
          <xs:element name="to" type="xs:string"/>
          <xs:element name="from" type="xs:string"/>
          <xs:element name="heading" type="xs:string"/>
          <xs:element name="body" type="xs:string"/>
        </xs:sequence>
      </xs:complexType>
    </xs:element>
    
    </xs:schema>

我想使用它来验证具有相同元素的XML文件，并且定义与XSD如下：

    <note
    xmlns="https://www.w3schools.com"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="https://www.w3schools.com/schema.xsd">
      <to>Tove</to>
      <heading>Reminder</heading>
      <from>Jani</from>
      <body>Don't forget me this weekend!</body>
    </note>

问题是，在示例中，服务器在示例中将元素发送出顺序，因此，当我运行代码时，它告诉我XML无效，即使我只有有效的元素。

    import xmlschema
    
    xsd_file = "schema.xsd"
    xml_file = "input.xml"
    
    xmlschema.validate(xml_file, xsd_file)

有没有办法可以在Python中验证此输入，忽略了元素出现的顺序？

执行该代码时，这是当前错误消息：

xmlschemachildrenvalidationError：失败验证＆lt; element'{https://www.w3schools.com}请注意'0x000002b13c7e7090＆gt; gt;使用XSDGroup（model ='sequence'，发生= [1，1]）：

原因：带标签'{https://www.w3schools.com}的意外孩子}'在位置2。

架构：

     <xs:complexType xmlns:xs="http://www.w3.org/2001/XMLSchema">
       <xs:sequence>
         <xs:element name="to" type="xs:string" />
         <xs:element name="from" type="xs:string" />
         <xs:element name="heading" type="xs:string" />
         <xs:element name="body" type="xs:string" />
       </xs:sequence>
     </xs:complexType>

实例：

      <note xmlns="https://www.w3schools.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://www.w3schools.com/schema.xsd">
        <to>Tove</to>
        <heading>Reminder</heading>
        <from>Jani</from>
        <body>Don't forget me this weekend!</body>
      </note>

Path: /note

原文

I have an XML Schema file that for the purpose of the example I'll use W3 school's one as follows:

    <?xml version="1.0"?>
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="https://www.w3schools.com" xmlns="https://www.w3schools.com" elementFormDefault="qualified">
    <xs:element name="note">
      <xs:complexType>
        <xs:sequence>
          <xs:element name="to" type="xs:string"/>
          <xs:element name="from" type="xs:string"/>
          <xs:element name="heading" type="xs:string"/>
          <xs:element name="body" type="xs:string"/>
        </xs:sequence>
      </xs:complexType>
    </xs:element>
    
    </xs:schema>

And I want to use it to validate an XML file that has the same elements, and definitions as the XSD like the following:

    <note
    xmlns="https://www.w3schools.com"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="https://www.w3schools.com/schema.xsd">
      <to>Tove</to>
      <heading>Reminder</heading>
      <from>Jani</from>
      <body>Don't forget me this weekend!</body>
    </note>

The problem is, as, in the example, the server sends the elements out of order, so, when I run the code bellow, it tells me that the XML is invalid, even though I only have valid elements.

    import xmlschema
    
    xsd_file = "schema.xsd"
    xml_file = "input.xml"
    
    xmlschema.validate(xml_file, xsd_file)

Is there a way that I can validate this input in python ignoring the order that the elements appear on?

This is the current error message when executing that code:

XMLSchemaChildrenValidationError: failed validating <Element '{https://www.w3schools.com}note' at 0x000002B13C7E7090> with XsdGroup(model='sequence', occurs=[1, 1]):

Reason: Unexpected child with tag '{https://www.w3schools.com}heading' at position 2. Tag 'from' expected.

Schema:

     <xs:complexType xmlns:xs="http://www.w3.org/2001/XMLSchema">
       <xs:sequence>
         <xs:element name="to" type="xs:string" />
         <xs:element name="from" type="xs:string" />
         <xs:element name="heading" type="xs:string" />
         <xs:element name="body" type="xs:string" />
       </xs:sequence>
     </xs:complexType>

Instance:

      <note xmlns="https://www.w3schools.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://www.w3schools.com/schema.xsd">
        <to>Tove</to>
        <heading>Reminder</heading>
        <from>Jani</from>
        <body>Don't forget me this weekend!</body>
