[OpenLayers-Users] Drawing on the fly route

[Matthew Pulis]

Hi guys :)

I am trying to make an on-the-fly route display.

I managed to send the request to the PHP page to generate and XML response
and a copy of this response can be found here :
http://yancho.pastebin.com/f41432b0d . The URL which is sending the data is
:
http://yancho.no-ip.org/~yancho/routing.php?startpoint=642983.5%20225176.75&finalpoint=641780.375%20224942.375&method=SPA&region=streets&srid=-1&_=
And these are the headers of the reply according to FireBug :
http://yancho.pastebin.com/f18cadf12

Small Extract Of the XML Output :

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<route>
<edge id='1'>
<id>3612</id>
<wkt>MULTILINESTRING((642847.022664808 225275.125294559,642901.453947967
225273.479351758))</wkt>
<length>0.054</length>
</edge>

But the problem is when I get to display the route. When I click on Compute
Route, on my site : http://yancho.no-ip.org/~yancho/openl.html

I get this error :

String contains an invalid character" code: "5
http://yancho.no-ip.org/~yancho/OpenLayers.js
Line 554

And further investigations in FireBug shows :

String contains an invalid character" code: "5
emptyFunction()OpenLayers.js (line 189)
getImagesLocation()OpenLayers.js (line 101)
emptyFunction()OpenLayers.js (line 189)

Any idea how I can fix my code please? A copy of the code can be seen
highlighted here : http://yancho.pastebin.com/f335b8727

I am following this tutorial :

Thanks for your continous help. Much Appreciated
