我试图使用 python 验证 XMl 文件 aginst xsd

问：

这是我的XML文件：

\<Orderdetails\>
\<Customer id="011"\>
\<cname\>Mark Lewis\</cname\>
\<destination Country="Australia" Delivdate=" 6 days"\>Free Delivery\</destination\>
\<eid\>[email protected]\</eid\>
\</Customer\>
\<Customer id="022"\>
\<fname from="jersey"\>Loafther cris\</fname\>
\<destination Country="USA" Delivdate=" 11 days"\>Shipping Charges\</destination\>
\<eid\>[email protected]\</eid\>
\</Customer\>
\<Customer id="033"\>
\<cname\>Amal Raj\</cname\>
\<destination Country="Thailand" Delivdate=" 6 days"\>Shipping Charges\</destination\>
\<email\>[email protected]\</email\>
\</Customer\>
\</Orderdetails\>

这是我的 XSD 文件：

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:attribute name="id" type="xs:unsignedByte" use="required" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

错误：

出现以下错误：

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

我在运行过程中遇到的错误

法典： 我正在尝试使用下面编写的代码进行验证：

from lxml import etree
from validator import validate

def validate(xml_path: str, xsd_path: str) -> bool:

    xmlschema_doc = etree.parse(xsd_path)
    xmlschema = etree.XMLSchema(xmlschema_doc)
    xml_doc = etree.parse(xml_path)
    result = xmlschema.validate(xml_doc)

    return result
    
    
xml_path="C:\Users\nisha\Downloads\xmlfile\demo.xml"
xsd_path="C:\Users\nisha\Downloads\xsdfile\demo.xsd"

value=validate(xml_path,xsd_path)
print(value)

随着路径中的双斜杠，它变得更远，但现在出现以下错误：

ModuleNotFoundError: No module named 'validator'
