Hey guys,
I have a form accepting a KML file from users and from there I want to
draw polylines based on a KML file's
<Placemarker><LineString><coordinates> element.
The problem I am having is that sometimes the KML file can have a
<document><folder> or <folder><document> or none of the above, or any
number of random scenarios in the KML file making it hard to parse.
To deal with this randomness I'm using an xpath and I think I have it
right but it just wont work... the code:
$result = $xml->xpath('Placemark/LineString/coordinates');
An the particular XML file I am trying to pull from looks like:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1";>
<Document>
<name>coehilltotweed.kml</name>
<Style id="lineStyle">
<LineStyle>
<color>64eeee17</color>
<width>6</width>
</LineStyle>
</Style>
<Folder>
<name>23-SEP-06</name>
<Snippet maxLines="2">
</Snippet>
<description><![CDATA[<table>
<tr><td><b>Distance</b> 139.0 mi </td></tr>
<tr><td><b>Min Alt</b> 451.4 ft </td></tr>
<tr><td><b>Max Alt</b> 1168.9 ft </td></tr>
</table>]]></description>
<Placemark>
<name>Path</name>
<styleUrl>#lineStyle</styleUrl>
<LineString>
<tessellate>1</tessellate>
<coordinates>
-77.827985,44.851878,311.109985
-77.82702000000001,44.852114,313.993896
-77.827213,44.85067600000001,313.513306
-77.827792,44.850955,313.513306
-77.830389,44.85333700000001,315.916504
-77.833114,44.858379,317.358643
-77.83193300000001,44.858508,313.993896 </coordinates>
</LineString>
</Placemark>
</Folder>
</Document>
</kml>
Any ideas why this won't work?
Thanks!
