XSLT seleziona valori distinti utilizzando gli attributi

Question

Sto provando a trasformare un elenco in un elenco di valori distinti utilizzando XSLT.

ingresso:

<object name="obj1"/> 
<object name="obj2"/> 
<object name="obj1"/> 

output desiderato:

<object>obj1</object> 
<object>obj2</object> 

Qualcuno un'idea di come farlo fare sia in XSLT 1.0 o 2.0?

Answer 1

Usa XSLT 2.0 e

<xsl:for-each select="distinct-values(//object/@name)"> 
    <object><xsl:value-of select="."/></object> 
</xsl:for-each> 

o

<xsl:for-each-group select="//object" group-by="@name"> 
    <object><xsl:value-of select="current-grouping-key()"/></object> 
</xsl:for-each-group>
