cvc-complex-type.2.3:元素“group"不能有字符 [children]，因为该类型的内容类型是 element-only [英] cvc-complex-type.2.3: Element 'group' cannot have character [children], because the type's content type is element-only

问题描述

我需要从这个 XSD 创建 XML:

 <?xml version="1.0" encoding="UTF-8"?>
<xs:schema 
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="group">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="person" minOccurs="5" maxOccurs="20" type="xs:string"/>
            </xs:sequence>
            <xs:attribute name="name" use="required" type="xs:string"/>
        </xs:complexType>
    </xs:element>
</xs:schema>

这是我尝试过的 XML:

<?xml version="1.0" ?>
<group name="abcd">
    xmlns="www.example.org"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="ex1.xsd">
    <person>Joao</person>
    <person>Andre</person>
    <person>Filipe</person>
    <person>Joaquim</person>
    <person>Rui</person>
</group>

我收到此错误:

无效.错误 - 第 10、9 行:org.xml.sax.SAXParseException；行号:10；列数:9；cvc-complex-type.2.3:元素group"不能有字符 [children]，因为该类型的内容类型是 element-only.

Not valid. Error - Line 10, 9: org.xml.sax.SAXParseException; lineNumber: 10; columnNumber: 9; cvc-complex-type.2.3: Element 'group' cannot have character [children], because the type's content type is element-only.

推荐答案

问题数量:

• 正如 Filburt 提到的，您过早地关闭了开放的组标签.这是您立即出错的直接原因.它导致解析器将您打算作为文本的属性误解为文本group 元素的内容.
• schemaLocation 必须采用命名空间-XSD pairs.
• elementFormDefault="qualified"
• 等

• As Filburt mentioned, you've prematurely closed the opening group tag. This is the direct cause of your immediate error. It causes the parser to misinterpret what you intend to be attributes as text content to the group element.
• schemaLocation must take namespace-XSD pairs.
• elementFormDefault="qualified"
• etc.

总的来说，以下 XSD 将成功验证以下 XML.

Altogether, the following XSD will validate the following XML successfully.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           targetNamespace="http://www.example.org"
           elementFormDefault="qualified">
  <xs:element name="group">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="person" minOccurs="5" maxOccurs="20" type="xs:string"/>
      </xs:sequence>
      <xs:attribute name="name" use="required" type="xs:string"/>
    </xs:complexType>
  </xs:element>
</xs:schema>

XML

<?xml version="1.0" ?>
<group name="abcd"
       xmlns="http://www.example.org"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.example.org ex1.xsd">
  <person>Joao</person>
  <person>Andre</person>
  <person>Filipe</person>
  <person>Joaquim</person>
  <person>Rui</person>
</group>
