使用for-each的XSLT验证

[英]XSLT Validation using for-each

问题描述

我正在尝试为XSLT验证模板编写逻辑，以检查XML消息的各种情况下是否存在重复循环。

消息的结构是 

<VXU_V04.ORDER> One or more may be present, not a required group; I’m calling this “OrderGroup”
<ORC> Required; only one ORC Segment per OrderGroup allowed
<ORC.3> Required; only one ORC.3 field per ORC Segment allowed
<EI.1>, <EI.2>, <EI.3> and <EI.4> are sub-components of ORC.3

这四个字段具有自己需要验证的代码。 每个ORC段只有一个ORC.3，每个ORC.3只有一组EI子组件。 但是，我仍然具有在订单组中考虑多个ORC段的概念，因此我仍然需要使用for-each构造来考虑多个ORC段。

这是我的ORC.3验证模板： 

<xsl:stylesheet version="2.0" xmlns:a="urn:hl7-org:v2xml" xmlns:dil="http://www.aegis.net/msg/filter/jaxb/rule" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <!--      
         Must be VALUED AND 
         Must not repeat
         -->
    <xsl:variable name="OrderGroup" select="/a:VXU_V04/a:VXU_V04.ORDER"/>
    <xsl:variable name="ORCSegment" select="/a:VXU_V04/a:VXU_V04.ORDER/a:ORC"/>
    <xsl:variable name="ORC3Field" select="/a:VXU_V04/a:VXU_V04.ORDER/a:ORC/a:ORC.3"/>
    <xsl:variable name="EI1Field" select="/a:VXU_V04/a:VXU_V04.ORDER/a:ORC/a:ORC.3/a:EI.1"/>

             </xsl:for-each>      
        </dil:filterruleresult>
    </xsl:template>
</xsl:stylesheet>

问题在于该模板根本找不到我的EI字段。 我一直陷于错误“当出现加注单编号时，需要实体标识符（ORC-3 / EI-1）”。 但是我的测试消息中确实有EI-1值。

这是我的测试消息的相关部分：

当您寻找EI.x字段时，您的级别还不正确： 

<xsl:for-each select="a:ORC">
 <xsl:choose>
     <xsl:when test="count(a:ORC.3)= 0">
        <dil:message type="error">ORC-3 Filler Order Number not found but is required.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:ORC.3)> 1">
         <dil:message type="error">Only one Filler Order Number (ORC-3) allowed per Order Segment.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:EI.1)> 1">
         <dil:message type="error">When present, only one Filler Order Number (ORC-3) allowed per Order Segment.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:EI.1)= 0">
         <dil:message type="error">When Filler Order Number Present, Entity Identifier (ORC-3/EI-1) is required.</dil:message>
     </xsl:when>
      <xsl:when test="count(a:EI.3)= 0 and count(a:EI.2)= 0">
         <dil:message type="error">When Filler Order Number Present, Namespace ID (ORC-3/EI-2) or Universal ID (ORC-3/EI-3) is required.</dil:message>
     </xsl:when>  
     <xsl:when test="count(a:EI.3)= 1 and count(a:EI.4)= 0">
       <dil:message type="error">When Filler Order Number Universal ID is present, Universal ID Type (ORC-3/EI-4) is required.</dil:message>
     </xsl:when>
     <xsl:when test="count(a:EI.3)= 0 and count(a:EI.4)= 0">
      <dil:message type="error">When Filler Order Number Universal ID is not present, Universal ID Type (ORC-3/EI-4) is not supported.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:ORC.3)= 1">
         <dil:message type="info">Value of '<xsl:value-of select="./a:EI.1"/>', '<xsl:value-of select="./a:EI.2"/>', '<xsl:value-of select="./a:EI.3"/>', '<xsl:value-of select="./a:EI.4"/>' found for Filler Order Number (ORC-2).</dil:message>
     </xsl:when>
 </xsl:choose>
</xsl:for-each>

您需要添加另一个级别才能进入EI。 您可以使用额外的for-each / select或通过如下更改xpath来进行此操作。 

<xsl:for-each select="a:ORC">
 <xsl:choose>
     <xsl:when test="count(a:ORC.3)= 0">
        <dil:message type="error">ORC-3 Filler Order Number not found but is required.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:ORC.3)> 1">
         <dil:message type="error">Only one Filler Order Number (ORC-3) allowed per Order Segment.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:ORC.3/a:EI.1)> 1">
         <dil:message type="error">When present, only one Filler Order Number (ORC-3) allowed per Order Segment.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:ORC.3/a:EI.1)= 0">
         <dil:message type="error">When Filler Order Number Present, Entity Identifier (ORC-3/EI-1) is required.</dil:message>
     </xsl:when>
      <xsl:when test="count(a:ORC.3/a:EI.3)= 0 and count(a:ORC.3/a:EI.2)= 0">
         <dil:message type="error">When Filler Order Number Present, Namespace ID (ORC-3/EI-2) or Universal ID (ORC-3/EI-3) is required.</dil:message>
     </xsl:when>  
     <xsl:when test="count(a:ORC.3/a:EI.3)= 1 and count(a:ORC.3/a:EI.4)= 0">
       <dil:message type="error">When Filler Order Number Universal ID is present, Universal ID Type (ORC-3/EI-4) is required.</dil:message>
     </xsl:when>
     <xsl:when test="count(a:ORC.3/a:EI.3)= 0 and count(a:ORC.3/a:EI.4)= 0">
      <dil:message type="error">When Filler Order Number Universal ID is not present, Universal ID Type (ORC-3/EI-4) is not supported.</dil:message>
     </xsl:when> 
     <xsl:when test="count(a:ORC.3/a:ORC.3)= 1">
         <dil:message type="info">Value of '<xsl:value-of select="./a:EI.1"/>', '<xsl:value-of select="./a:EI.2"/>', '<xsl:value-of select="./a:EI.3"/>', '<xsl:value-of select="./a:EI.4"/>' found for Filler Order Number (ORC-2).</dil:message>
     </xsl:when>
 </xsl:choose>
</xsl:for-each>
