XML架构＆amp; xml文档未验证

Question

我想知道你是否可以指出我的架构有什么问题？我已经使用 - http://www.utilities-online.info/xsdvalidation/#.VQkt1BCUfA4检查了我的XML文档是否格式正确 - 它已经很好地形成了。但是，当我针对我的schema文档检查xml时，它会显示大量的错误。我真的不知道自己在架构中做错了什么！如果有人能给我一个很棒的牌。

grant.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE grant [
    <!ELEMENT grant (title, agency, department, summary, initiated, expires, coordinator)>
    <!ATTLIST grant grantNum ID #REQUIRED>
    <!ATTLIST grant funding (federal|state|local|private) #REQUIRED>

    <!ELEMENT title (#PCDATA)>
    <!ELEMENT agency (#PCDATA)>
    <!ELEMENT department (#PCDATA)>
    <!ELEMENT summary (#PCDATA)>
    <!ELEMENT initiated (#PCDATA)>
    <!ELEMENT expires (#PCDATA)>
    <!ELEMENT coordinator (#PCDATA)>

如果我的架构错误，请告诉我！

Answer 1

首先（根据此验证器：http://www.utilities-online.info/xsdvalidation/）：您的xs文件格式不正确。你必须声明元素'summary'，只需按时声明并在需要时引用它两次。当您使用xsd文件中的自定义类型时，您不能说命名空间中有自定义类型，因此请移除xs:和type='xs:grantNumFormat'

中的type='xs:fundingFormat'
