Issue parsing coordinates

[seang96]

I am getting an exception thrown on a specific kml file trying to read coordinates. Apparently it has null values which are not supported.

Error output:

System.Xml.XmlException

That exception looks like the XML data is malformed - can you run it through an XML validator to see if there are any issues with the data?

If that checks out ok, can you attach a minimal file that reproduces the error and I'll take a look at it.

[seang96]

I checked it with a few online XML validators and it was valid every time. I attached a zip with the entire file.
file.zip

I can't reproduce that error, the following works for me (.NET Core console app on Windows 10):

KmlFile kml = KmlFile.Load(File.OpenRead(FileName));

Inspecting the kml object I can see all the co-ordinates in it as well. I've also tried the ParseString method, using File.ReadAllText() and can't replicate it.

How are you getting the string and is there a null character in it?

Through a download. My downloader was not working correctly, making this issue fixed.
