我正在尝试为XML文件创建架构，但不断收到验证错误。我有过丰富的XML，XSLT和DTD经验，但当我被要求创建XSD文件时，我认为我可以解决这个问题。我被要求创建具有以下规范的模式：
<payroll>
<employee>+
<name>
<first>: string of upper/lowercase letters, spaces, or hyphens (-).
string must start with an uppercase letter
<middle>?: upper case letter
<last>: string of upper/lowercase letters, spaces, or hyphens (-).
string must start with an uppercase letter
<spouse>? –- first, middle, last are the same type as for employee
<first>
<middle>?
<last>
<child>* -- first, middle, last are the same type as for employee
<first>
<middle>?
<last>
<tax-status> married | single | headOfHousehold | separated
<ssn>: A nine digit number of the form ddd-dd-dddd (e.g, 865-57-2934)
ssn attribute: name=type; values=(assigned | original); default="original"
<salary>: A 9 digit number of the form ddddddd.dd with a minimum value of
0 and a maximum value of 2000000, inclusive.
<date-of-birth>: A date type
<manager> | <staff>
<manager>
attribute for manager: name=title; type=string; use=required
<department>: string
<yrsAtRank>: an inclusive integer between 0 and 50
<staff>
<skill>+: up to 5 skills, each being a string
这是XML文件：
<?xml version = "1.0"?>
<employeelist:payroll xmlns:employeelist = "urn:myURN:employeelist">
<employee>
<name>
<first>Brad</first>
<middle>T</middle>
<last>Vander Zanden</last>
</name>
<spouse>
<first>Yifan</first>
<last>Tang</last>
</spouse>
<tax-status>married</tax-status>
<ssn type="assigned">186-39-3069</ssn>
<salary>110000.00</salary>
<date-of-birth>1964-02-03</date-of-birth>
<manager title="professor">
<department>Computer Science</department>
<yrsAtRank>8</yrsAtRank>
</manager>
</employee>
<employee>
<name>
<first>Don</first>
<last>Juan</last>
</name>
<child>
<first>Mary</first>
<middle>H</middle>
<last>Lamb</last>
</child>
<child>
<first>Fred</first>
<last>Flintstone</last>
</child>
<tax-status>headOfHousehold</tax-status>
<ssn>586-38-3969</ssn>
<salary>1553.83</salary>
<date-of-birth>1980-07-07</date-of-birth>
<staff>
<skill>Carpentry</skill>
<skill>Welding</skill>
<skill>Plumbing</skill>
</staff>
</employee>
</employeelist:payroll>
而且..这里是XSD（下面）。我找不到问题。 W3C验证器只是说：“标记没有很好地形成。”任何线索或想法？提前谢谢！

答案 0 :(得分：1)
您已将“payroll”的类型定义为“singleEmployeeType”，因此它希望单个员工（name，spouse等）的元素直接位于<payroll>内元件。这与您输入的XML不匹配，并且看起来不像您想要的那样。
只需将XSD中payroll元素的定义更改为：
<element name="payroll" type="employeelist:employeeType"/>
在您的XSD中，您将employeeType定义为1个或多个<employee>元素。我建议你修改XSD中类型的命名，以确定它是否只接受一个或多个东西。无论您喜欢什么样的惯例都很好，只要它一致。只要您始终使用“复数”或“添加列表”惯例，就可以将employeeType重命名为employeesType或employeeListType。
