Question

我在XSLT中有两个if条件，如下所示：

 <xsl:if test="ns2:RoadPart/ns2:Vehicles/ns3:SemiVehicle>// for semi vehicle
 //code to show values from XML(ie 20,20)
</xsl:if>

 <xsl:if test="ns2:RoadPart/ns2:Vehicles/ns3:NonsemiVehicle>// for non-semivehicle
 //code to show values from XML(ie 10,10)
</xsl:if>

我的XML如下：

// For Non semi vehicle
<RoutePart Id="374941">
<Vehicles>
<NonsemiVehicle>
<OverallLengthListPosition xmlns="http://www.esdal.com/schemas/core/vehicle">
              <OverallLength>
                <IncludingProjections>10</IncludingProjections>
                <ExcludingProjections>10</ExcludingProjections>
              </OverallLength>
            </OverallLengthListPosition>
</NonsemiVehicle>
</Vehicles>
</RoutePart>

// For Semi vehicle
<RoutePart Id="374941">
<Vehicles>
<SemiVehicle>
<OverallLengthListPosition xmlns="http://www.esdal.com/schemas/core/vehicle">
              <OverallLength>
                <IncludingProjections>20</IncludingProjections>
                <ExcludingProjections>20</ExcludingProjections>
              </OverallLength>
             </OverallLengthListPosition>
</SemiVehicle>
</Vehicles>
</RoutePart>

每当我首次列出SemiVehicle并将非赛车列为第二时，我解析此XSLT。我每次都根据我给定的XML动态地想要这个。

请帮帮我。

Answer 1

为什么需要这些有条件的检查？如果您只是使用

<xsl:template match="/">
  <xsl:apply-templates select="ns2:RoadPart/ns2:Vehicles/*"/>
</xsl:template>

处理Vehicles的所有子元素，或者如果有一些你不想处理的元素，当然也可以使用

<xsl:template match="/">
  <xsl:apply-templates select="ns2:RoadPart/ns2:Vehicles/ns3:SemiVehicle | ns2:RoadPart/ns2:Vehicles/ns3:NonsemiVehicle"/>
</xsl:template>

加上一个模板（或更多），用于输出您想要输出的值，然后按文档顺序处理和输出元素。

Answer 2

你的病情

Stream<String> names = Arrays.asList("NAME A", "NAME B", "NAME A").stream();
final Stream<String> distinct = names.distinct();
System.out.println(distinct.collect(Collectors.joining(",")));

如果找到至少一个SemiVehicle，条件

，则

为真

ns2:RoadPart/ns2:Vehicles/ns3:SemiVehicle

如果找到至少一个NonsemiVehicle，则

为真。

因此通常两个条件都是正确的，并且两个分支都将被执行。我怀疑这不是你想要的。我怀疑你想要处理所有的车辆，对于SemiVehicles和NonsemiVehicles有不同的逻辑。

那是什么模板规则。我认为你的代码应该是这样的：

ns2:RoadPart/ns2:Vehicles/ns3:NonsemiVehicle

然后

<xsl:apply-templates select="ns2:RoadPart/ns2:Vehicles/*"/>

除了两种车辆的结构看起来如此相似以至于您可能希望对两者使用相同的模板规则。
