如何在XML模式中使這兩個字段成為強制性

Question

我有一個要求，例如ParcelNumber或諸如CoordinateX或CoordinateY強制性的CoordinateY ，這兩個要求在XML中包含不同的層次結構。 因此，如果輸入的xml包含包裹編號，則它應該返回成功，或者如果它包含兩個坐標，那么它應該返回成功。我創建了以下模式，如果我僅發送包裹編號，但是如果我發送Co-，它將返回成功。縱坐標它將失敗，它要求發送錯誤的包裹號。如何實現。在果殼中，我有以下問題

1>If i send both coordinates  and no parcel number it should return success
2>IF i send x coordinate then it should fail and ask to send Y co ordinate

以下是我到目前為止所做的

編輯任何有關如何在此處正確使用choice想法

Answer 1

您可以執行以下操作：

<xs:choice>
  <xs:sequence>
    <xs:element name="ParcelNumber" />
    <xs:element name="CoOrdinates" minOccurs="0" />
  </xs:sequence>
  <xs:sequence>
    <xs:element name="CoOrdinates" />
    <xs:element name="ParcelNumber" minOccurs="0" />
  </xs:sequence>
</xs:choice>

Answer 2

嘗試這個

  <xsd:complexType name="WorkLocationCoordinateType">
        <xsd:sequence>
            <xsd:element name="CoordinateX" type="xsd:string" minOccurs="1"/>
            <xsd:element name="CoordinateY" type="xsd:string" minOccurs="1"/>
        </xsd:sequence>
    </xsd:complexType>
