 I have a template like this...

 <xsl:template name="dibujaEje">

  <line x1="16%" y1="85%" x2="16%" y2="15%"/>
  <line x1="17%" y1="85%" x2="17%" y2="15%"/>
   :    :             :                :
  <line x1="84%" y1="85%" x2="84%" y2="15%"/>
  <line x1="85%" y1="85%" x2="85%" y2="15%"/>

 </xsl:template>


 The attributes of the element line, x1 and x2 change from 16% to 85%...

 How i could simplify this and haven't to write all the lines?¿?

By using a recursive call as illustrated below. Note how the countervariable is initialized to 16 and gets called again until the 85 is writtenout.


I hope this helps.
