我正在尝试解决这个问题，但不能理解这个错误的根本原因：
Invalid Content Was Found Starting With Element ‘country’. One Of ‘{country}’ Is Expected.. Line ’10’,Column ’14’
这是我的xml：
<?xml version="1.0"?>
<!--DTD file reference-->
<!--<!DOCTYPE countries SYSTEM "http://localhost:8080/ajaxprac/file.dtd">-->
<!--DTD file reference-->
<!---->
<countries xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://localhost:8080/ajaxprac"
xsi:schemaLocation="http://localhost:8080/ajaxprac fileSchema.xsd">
<country>
<name>pakistan</name>
<cities>
<city>Kassowal</city>
<city>Faisalabad</city>
<city>Multan</city>
</cities>
</country>
<country>
<name>india</name>
<cities>
<city>Agra</city>
<city>Amritsar</city>
<city>Ayodhya</city>
</cities>
</country>
</countries>
而xsd文件是：
<?xml version="1.0"?>
<!--

<xs:schema version="1.0"

<xs:element name="name" type="xs:string"/>
<xs:element name="city" type="xs:string"/>
<xs:complexType name="countriesType">

<xs:element name="country" type="countryType"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="countryType">
<xs:sequence>
<xs:element ref="name"/>
<xs:element name="cities" type="citiesType"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="citiesType">
<xs:sequence>
<xs:element ref="city"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
如你所愿，您的架构期望“全球”国家，名称和城市元素位于http：// localhost：8080 / ajaxprac命名空间中，而“local”元素(在complexType(即国家和城市)内)没有命名空间。你可能想添加
elementFormDefault="qualified"，即
<xs:schema version="1.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://localhost:8080/ajaxprac"
xmlns="http://localhost:8080/ajaxprac"
elementFormDefault="qualified">
它将targetNamespace应用于本地以及全局元素声明。
