xml - 错误 : The prefix "xsi" for attribute "xsi:schemaLocation" is not bound

Question

我无法根据 XSD 验证我的 XML。验证器抛出

The prefix "xsi" for attribute "xsi:schemaLocation" associated with an element type "mpreader" is not bound.

这是一个 XML 剪辑

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<mpreader xmlns="C:\Users\Dallan\Desktop\Mpreader\" xmlns:xs="http://www.w3.org/20one/XMLSchema-instance" 
 xsi:schemaLocation="C:\Users\Dallan\Desktop\Mpreader\mpreaderschemafinal.xsd"> 
                <firmware>"3.4.16"</firmware>  

                <hardware>"2.3.53"</hardware>  

                <sn>"234-1three5"</sn>

                <devices> 
            </devices>
        </mpreader>

这是 XSD 剪辑

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="C:Users/Dallan/Desktop/Mpreader/" elementFormDefault="qualified" targetNamespace="C:\Users\Dallan\Desktop\Mpreader\">

<xs:element name="mpreader">
<xs:complexType>
<xs:sequence maxOccurs="unbounded">
    <xs:element name="firmware" type="xs:string"/>
    <xs:element name="hardware" type="xs:string"/>
    <xs:element name="sn" type="xs:string"/>
    <xs:element name="devices">
        <xs:complexType>
        <xs:sequence maxOccurs="unbounded">
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Answer 1

“与元素类型“mpreader”关联的属性“xsi:schemaLocation”的前缀“xsi”未绑定(bind)。”

那就绑定(bind)吧，亲爱的达兰，亲爱的达兰，亲爱的达兰……

只需添加一个命名空间声明，将前缀 xsi 绑定(bind)到命名空间 http://www.w3.org/2001/XMLSchema-instance
