I have a peculiar problem with posting data via the /applyEdits rest endpoint to a service in ArcGIS Online.
The feature contains a string attribute "LOG_OPM" which contains the following text:
"kast 1 richting 2 3 A Groen <dub ov> vervangen nacht"
(double quotes added for clarity)
When posting this as an update through the applyEdits endpoint, the following error is returned:
Field LOG_OPM has invalid html content
Obviously this is not meant to be HTML but the parser thinks it is.
Escaping the < and > like this:
"kast 1 richting 2 3 A Groen \u003cdub ov\u003e vervangen nacht"
results in the same error.
How should I escape or encode this string so that the parser stores it properly without thinking it's invalid HTML?
This is part of a C# application, I should add.
Thanks in advance,
