xsl: option de clé de filtre pour afficher les valeurs de données dans différentes lignes

Question

je subirai xml comme ci-dessous:

Il y a deux nœuds d'arbre qui diffère noeud. Lorsque je boucle et utilise le code que je reçois deux valeurs dans la même ligne. Essayé de le filtrer avec le noeud, mais n'a pas pu filtrer. Quelqu'un peut-il s'il vous plaît fournir les pointeurs? problème est avec la troisième rangée.

Answer 1

Il semble que vous avez besoin d'un xsl:for-each sur bmCalYearDet puis ajouter une condition sur la clé pour filtrer le benchMarkOrder

<!-- 3rd row here is the issue with the code--> 
<xsl:for-each select="performanceVO/bmCalYearDet"> 
    <xsl:variable name="benchMarkOrder" select="benchMarkOrder" /> 
    <tr> 
     <th>val</th> 
     <xsl:for-each select="$years/fAnReVal"> 
      <td> 
       <xsl:value-of select="key('bmCalDet-by-year', substring-before(rtnDate, '-'), $catalog)[../benchMarkOrder = $benchMarkOrder]/val" /> 
      </td> 
     </xsl:for-each> 
    </tr> 
</xsl:for-each> 

Comme vous utilisez XSLT 2.0, vous pouvez aussi écrire comme si

<!-- 3rd row here is the issue with the code--> 
<xsl:for-each select="performanceVO/bmCalYearDet"> 
    <xsl:variable name="benchMarkOrder" select="." /> 
    <tr> 
     <th>val</th> 
     <xsl:for-each select="$years/fAnReVal"> 
      <td> 
       <xsl:value-of select="key('bmCalDet-by-year', substring-before(rtnDate, '-'), $benchMarkOrder)/val" /> 
      </td> 
     </xsl:for-each> 
    </tr> 
</xsl:for-each> 

Answer 2

Regardez vos données. Par exemple. pour l'année 2016, vous avez deuxbmCalDet nœuds. Un avec val = 11,96 et un autre avec val = -21,68.

Les deux ces noeuds sont retournés lorsque vous appelez key('bmCalDet-by-year',...) pour l'année 2016.

Ainsi, lorsque vous créez la ligne # 3, vous avez besoin que la première de ces valeurs. Ensuite, changez l'instruction dans la boucle:

<xsl:value-of select="key('bmCalDet-by-year', substring-before(rtnDate, '-'), 
    $catalog)[1]/val" /> 

Remarque [1] ajouté pour obtenir seulement le 1er nœud retourné par key.

Pour obtenir le second ensemble de valeurs (sur la ligne 4), répétez l'ensemble du fragment en créant la ligne 3. Cette fois cependant, à l'intérieur de la boucle for-each, vous avez besoin de seulement le deuxième élément du contenu retourné par key(...). Donc, au lieu de [1] (après key(...)), écrivez [2].
