如何使无论是在XML架构强制性的字段 [英] How to make either of the fields mandatory in XML schema

问题描述

我有这样一个要求为 ParcelNumber 或坐标像 CoordinateX 或 CoordinateY 强制性的，这两个包含XML不同的层次。因此，如果输入XML包含宗地编号应该返回成功，或者如果它包含坐标，那么它应该返回success.I创建下面的架构，它将返回成功，如果我只发送包裹数量，但如果我派合作坐标它会失败，它要求发送包裹数量是wrong.How实现it.In果壳我有以下问题

I have a requirement like either ParcelNumber or co-ordinates like CoordinateX or CoordinateY mandatory and these two contains different hierarchy in XML . So if the input xml contains parcel number it should return success or if it contains both co-ordinates, then it should return success.I created following schema ,and it will return success if i send only parcel number, but if i send Co-ordinates it will fail ,it is asking to send parcel number which is wrong.How to achieve it.In Nutshell i have following question

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

以下是我迄今所做

推荐答案

您可以做这样的事情： -

You can do something like this:-

<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>
