DataSet 加载XML 数据效果

.NET 能将 XML 架构和数据读入 DataSet
对于如下的XML
<?xml version="1.0" encoding="utf-8" ?>
<dsPubs>
  <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="dsPubs">
      <xs:complexType>
        <xs:sequence>
          <xs:element maxOccurs="unbounded" name="authors">
            <xs:complexType>
              <xs:sequence>
                <xs:element name="au_id" type="xs:string" />
                <xs:element name="au_lname" type="xs:string" />
                <xs:element name="au_fname" type="xs:string" />
                <xs:element name="au_phone" type="xs:string" />
                <xs:element name="orders">
                  <xs:complexType>
                    <xs:sequence>
                      <xs:element maxOccurs="unbounded" name="order" type="xs:unsignedByte" />
                    </xs:sequence>
