[oXygen-user] how to change value of attributes

[George Cristian Bina]

Hi,

It is not very clear from your description what is the algorithm to 
compute the new values. Assuming that you want those values only on the 
level 3 div elements and they will continue with carta 3r, carta 3v, 
carta 4r, etc. then something like below should do it:


   <xsl:template match="node() | @*">
     <xsl:copy>
       <xsl:apply-templates select="node() | @*"/>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="/mets:div/mets:div/mets:div">
     <xsl:copy>
       <xsl:apply-templates select="@*"/>
       <xsl:attribute name="LABEL">
         <xsl:text>Carta </xsl:text>
         <xsl:variable name="index" 
select="count(preceding::mets:div[parent::mets:div/parent::mets:div])"/>
         <xsl:value-of select="($index - $index mod 2) div 2 + 1"/>
         <xsl:value-of select="if ($index mod 2 = 0) then 'r' else 'v'"/>
       </xsl:attribute>
       <xsl:apply-templates select="node()"/>
     </xsl:copy>
   </xsl:template>

Best Regards,
George
