xml文档未验证为xsd架构

Question

使用eclipse时，我消除了所有错误，但当我更改xml文档中的元素内容时，超出了中设置的限制。xsd文件没有出现验证错误。我已尝试使用联机验证http://www.freeformatter.com/xml-validator-xsd.html我得到了错误“Cvc elt.1：找不到元素“DatabaseInventory”…行“4”，列“69”的声明”，但在eclipse中它验证得很好。不知道我做错了什么。

这是我的xml

      The following database should be considered the most stable for up-to-date 
      data. The backup strategy includes running the database in Archive Log Mode 
      and performing nightly backups. All new accounts need to be approved by the 
      DBA Group before being created.

Answer 1

你有两件事做错了。1.-架构中有：

 <xs:simpleType name="restricted-Type-values">
 <xs:restriction base="xs:string">
 <xs:enumeration value="Production"/>
 <xs:enumeration value="Development"/>
 <xs:enumeration value="Testing"/>
 <!--  converted enumerated list into discrete values--> 
 </xs:restriction>
 </xs:simpleType>

<OracleSID>Productio</OracleSID>

而且必须是

<OracleSID>Production</OracleSID>

这是有效值之一。

2.-您的XML中包含此元素：

<Administrator EmailAlias="jhunter" Extension="6007">

但未在XSD中定义。也许您想使用另一个元素：

<xs:element name="Administrator-type" type="Administrator-type" minOccurs="1" maxOccurs="3"/>

所以你必须替换这个：

    <Administrator EmailAlias="jhunter" Extension="6007">
       Jeffrey Hunter
    </Administrator>

用这个

    <Administrator-type EmailAlias="jhunter" Extension="6007">
        Jeffrey Hunter
    </Administrator-type>

Answer 2

在这种情况下，eclipse不执行任何验证，因为它无法将模式与实例文档相关联。

首先，您的模式没有指定目标命名空间，这意味着您的实例文档不应声明默认命名空间：

<DatabaseInventory xmlns="http://www.w3schools.com" >

将其更改为：

<DatabaseInventory >

其次，xsi： Schemaloce属性接受{URI， URL}对的列表，其中URI是命名空间URI，URL是相应模式的位置。但是，由于您的模式没有声明目标名称空间，因此您应该改用xsi： noNamespaceSchemaLoce属性。您的第一个元素应该如下所示：

<DatabaseInventory 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="DatabaseInventory.xsd">
