I am trying to count, in an XSLT file, how many coordinates are in the polygon object. I have looked all over the net how I could do that, but in vain. Does anyone know how I could do that? Just an useful link would suffice.
Thanks in avance.
If I understand correctly, the number of vertices in the polygon is equal to the number of commas inside the <Geometrie> text value + 1, so try:
<xsl:variable name="string" select="/Quartier/Geometrie" />
<xsl:value-of select="string-length(translate($string, translate($string, ',', ''), '')) + 1"/>
which returns 510 in your example.
Strictly speaking, the number of coordinates is twice that - but I doubt you meant that strictly.
