For a different take, here's the old school version I get to parse URL
items into an array:
// WebRequest_ParseURLItems
// Strip parameters off URL and parse the remainder into items.
// 4D automatically URL decodes the incoming data before it arrives.
// Otherwise, this routine would need to convert special characters
// encoded as hex in the incoming URL.
C_TEXT($1;$request_url)
$request_url:=Text_TrimLeadingSlash ($1) // Don't want a leading /
If ($request_url="@/") // Don't want a trailing /
$request_url:=Substring($request_url;1;Length($request_url)-1) // Drop
the first character.
End if
// This routine is only interested in regular URL items before any ?
// and special arguments.
C_LONGINT($question_mark_position)
$question_mark_position:=Position("?";$request_url)
If ($question_mark_position>0)
$request_url:=Substring($request_url;1;$question_mark_position-1)
End if
ARRAY TEXT(WebRequest_URLItems_at;0)
// Parse the script URL into array items:
Text_ParseIntoArray ($request_url;->WebRequest_URLItems_at;"/")
// Save the original URL in the 0 element:
WebRequest_URLItems_at{0}:=$request_url
// End of routine.
I've then got a function to read an item by position safely. I'd expect
that most of us have something like Text_ParseIntoArray in our toolkits
already.
