Question

我遵循xsd架构文件：

   <?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" attributeFormDefault="unqualified" elementFormDefault="qualified">

                      </xsd:complexType>
                    </xsd:element>
                  </xsd:sequence>

                <xsd:unique name="Content2NameUniqueKey">
                  <xsd:selector xpath="Content2" />
                  <xsd:field xpath="@Name" />
               </xsd:unique>
              </xsd:element>
            </xsd:sequence>
            <xsd:attribute name="Name" type="xsd:string" use="required" />
           </xsd:complexType>
          <xsd:unique name="Content1NameUniqueKey">
            <xsd:selector xpath="Content1" />
            <xsd:field xpath="@Name" />
          </xsd:unique>
        </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xs:schema>

使用唯一约束，我可以检查content1名称是否唯一，以及content1元素中是否所有content2 name都是unuique。

但我的问题是，我想检查所有content2元素中是否所有content2元素都是唯一的。因此，只能有一个名为＆＃34; xy＆＃34;的content1元素。在完整的XML文件中。

有人可以帮助我吗？

向所有人致以问候！

Answer 1

Content2的唯一元素只需在Modul中移动一级，使用XPath Content1/Content2。这样，Content2元素在整个Modul中也必须是唯一的。

AttributeType1的双重问题还有另一个问题，我将其替换为min/maxOccurs=2，但它可能只是一个错字。
