Also btw my XML structure is like so:
<datapoints>
<line id='lineTFT001' width="5">
<point latitude=" " longitude=" " In here are the
latitiude and longitude points for this segment of the road />
<point latitude=" " longitude=" " In here are the
latitiude and longitude points for this segment of the road />
</line>
.
.
<line id='lineTFT012' width="5">
<point latitude=" " longitude=" " In here are the
latitiude and longitude points for this segment of the road />
<point latitude=" " longitude=" " In here are the
latitiude and longitude points for this segment of the road />
</line>
</datapoints>
All advice and hints appreciated thanks. I've been stuck on this for
most of last week. I know I am close to clearing up this last issue
but I could use a hand.
Thanks again!
