xml - 将每个 Mappoint 下的坐标分组

Question

我正在尝试使用 XSLT 通过分组来处理数据。

示例 XML

  <DELIVERYLEG>

                <MAP_POINT_COMMENT />
            </maprows>
        </DELIVERYINSTRUCTION>
    </DELIVERYLEG>

它应该在 MAP_POINT_GROUP 上分组，并且所有坐标都应该属于该组。以下是输出除外....

<MapPoint MapPointDisplayType="Turning" MapPointType="UserWay">
    <MapPointName>695123</MapPointName>
    <MapPointComment>Kom</MapPointComment>
    <MapCoordinates>
        <Coordinates Order="1" Type="XY">695123</Coordinates>
    </MapCoordinates>                          
</MapPoint> 
<MapPoint MapPointDisplayType="Line" MapPointType="ForestRoad">
    <MapPointName>6951271</MapPointName>
    <MapCoordinates>
        <Coordinates Order="1" Type="XY">6951337</Coordinates>
        <Coordinates Order="2" Type="XY">6951271</Coordinates>
    </MapCoordinates>                          
</MapPoint> 
<MapPoint MapPointDisplayType="Line" MapPointType="ForestRoad">
    <MapPointName>6951479</MapPointName>
    <MapCoordinates>
        <Coordinates Order="1" Type="XY">6951479</Coordinates>
        <Coordinates Order="2" Type="XY">6951507</Coordinates>
        <Coordinates Order="3" Type="XY">6951598</Coordinates>
        <Coordinates Order="4" Type="XY">6951734</Coordinates>
    </MapCoordinates>                          
</MapPoint>

我将如何处理？

下面是现有的 XSLT

Answer 1

我创建了一些脚本：

XSLT：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:key name="group" match="maprows" use="MAP_POINT_GROUP"/>

  <xsl:template match="rows">
    <row>
      <xsl:apply-templates select="maprows[generate-id()=generate-id(key('group',MAP_POINT_GROUP))]"
      />
    </row>
  </xsl:template>

  <xsl:template match="maprows">
    <xsl:variable name="Group" select="MAP_POINT_GROUP"/>
    <MapPoint MapPointDisplayType="{MAP_POINT_TYPE}" MapPointType="{MAP_POINT_TYPE}">
      <MapPointName>
        <xsl:value-of select="MAP_POINT_NAME"/>
      </MapPointName>
      <MapCoordinates>
        <xsl:for-each select="parent::rows/maprows[MAP_POINT_GROUP=$Group]">
          <Coordinates Order="{position()}" Type="XY">
            <xsl:value-of select="MAP_POINT_NAME"/>
          </Coordinates>
        </xsl:for-each>
      </MapCoordinates>
    </MapPoint>
  </xsl:template>
</xsl:stylesheet>

输出：

<row>
   <MapPoint MapPointDisplayType="Turning" MapPointType="Turning">
      <MapPointName>695123</MapPointName>
      <MapCoordinates>
         <Coordinates Order="1" Type="XY">695123</Coordinates>
      </MapCoordinates>
   </MapPoint>
   <MapPoint MapPointDisplayType="ForestRoad" MapPointType="ForestRoad">
      <MapPointName>6951337</MapPointName>
      <MapCoordinates>
         <Coordinates Order="1" Type="XY">6951337</Coordinates>
         <Coordinates Order="2" Type="XY">6951271</Coordinates>
      </MapCoordinates>
   </MapPoint>
   <MapPoint MapPointDisplayType="ForestRoad" MapPointType="ForestRoad">
      <MapPointName>6951479</MapPointName>
      <MapCoordinates>
         <Coordinates Order="1" Type="XY">6951479</Coordinates>
         <Coordinates Order="2" Type="XY">6951507</Coordinates>
         <Coordinates Order="3" Type="XY">6951598</Coordinates>
         <Coordinates Order="4" Type="XY">6951734</Coordinates>
      </MapCoordinates>
   </MapPoint>
</row>

Answer 2

这里的解决方案基于 Muenchian 分组：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>

    <xsl:key name="kmaprows" match="maprows" use="MAP_POINT_GROUP"/>

    <xsl:template match="/">
        <row>
            <xsl:apply-templates select="//maprows[generate-id() = generate-id( key('kmaprows',MAP_POINT_GROUP)[1]) ]"  />
        </row>
    </xsl:template>

    <xsl:template match="maprows">
        <MapPoint MapPointDisplayType="{MAP_POINT_TYPE}" MapPointType="{MAP_POINT_TYPE}">
            <MapPointName>
                <xsl:value-of select="MAP_POINT_NAME"/>
            </MapPointName>
            <MapCoordinates>
                <xsl:for-each select="key('kmaprows',current()/MAP_POINT_GROUP)">
                    <Coordinates Order="{position()}" Type="{../XY_TEXT}">
                        <xsl:value-of select="MAP_POINT_NAME"/>
                    </Coordinates>
                </xsl:for-each>
            </MapCoordinates>
        </MapPoint>
    </xsl:template>
</xsl:stylesheet>

这将产生预期的输出：

<row>
  <MapPoint MapPointDisplayType="Turning" MapPointType="Turning">
    <MapPointName>695123</MapPointName>
    <MapCoordinates>
      <Coordinates Order="1" Type="XY">695123</Coordinates>
    </MapCoordinates>
  </MapPoint>
  <MapPoint MapPointDisplayType="ForestRoad" MapPointType="ForestRoad">
    <MapPointName>6951337</MapPointName>
    <MapCoordinates>
      <Coordinates Order="1" Type="XY">6951337</Coordinates>
      <Coordinates Order="2" Type="XY">6951271</Coordinates>
    </MapCoordinates>
  </MapPoint>
  <MapPoint MapPointDisplayType="ForestRoad" MapPointType="ForestRoad">
    <MapPointName>6951479</MapPointName>
    <MapCoordinates>
      <Coordinates Order="1" Type="XY">6951479</Coordinates>
      <Coordinates Order="2" Type="XY">6951507</Coordinates>
      <Coordinates Order="3" Type="XY">6951598</Coordinates>
      <Coordinates Order="4" Type="XY">6951734</Coordinates>
    </MapCoordinates>
  </MapPoint>
</row>
