Problems passing arguments in <href> element under a network link

[Tallywag]

Ok first post for help on KML everything up to this point has been
pretty straightforward !

I want to pass two arguments to my writeKML.php script from a network
link .KML file however all my attempts to do have failed.

<NetworkLink>
<Link>
<href>http://www...../writeKML.php?arga=A-
BCDE&argb=2008-04-16</href>
<refreshMode>onInterval</refreshMode>
<refreshInterval>300</refreshInterval>
</Link>
</NetworkLink>

When I tried the above but I got the "not well formed (invalid token)"
error message on loading the network link KML file.

URLencoding the above <href> line to....

<NetworkLink>
<Link>
<href>http%3A%2F%2Fwww.....%2FwriteKML.php%3Farga%3DA-BCDE
%26argb%3D2008-04-16</href>
<refreshMode>onInterval</refreshMode>
<refreshInterval>300</refreshInterval>
</Link>
</NetworkLink>

removes the error message and GE loads OK but I get the broken network
link icon (red dot)

If I hard code the arguments into the writeXML.php and remove the
arguments from the <href> element in the network link KML file
everything works fine.
That is ...

In writeXML.php ...
$arga = 'A-BCDE';
$argb = '2008-04-16'

In my network link KML file...
<NetworkLink>
<Link>
<href>http://www...../writeKML.php</href>
<refreshMode>onInterval</refreshMode>
<refreshInterval>300</refreshInterval>
</Link>
</NetworkLink>

So the question is how can I pass arguments to a php script in a
network link?

I hope I have made my requirments/problems clear !!!

Try replacing the & sign in your URL by &amp;

Hi Tallywag,

As KoflAIR suggested, you can escape it using &amp;
http://code.google.com/apis/kml/documentation/kmlreference.html#httpquery
You can also use the <httpQuery> element:

<NetworkLink>
<Link>
<href>http://www...../writeKML.php</href>

<httpQuery>arga=ABCDE;argb=2008-04-16</httpQuery>

<refreshMode>onInterval</refreshMode>
<refreshInterval>300</refreshInterval>
</Link>
</NetworkLink>
