Remove unwanted characters ([],) from a List-CodePudding

I am completing a List with data returned from an XML API.

I am now gain the data in the format I require and have the function to put those var's into a list as follows

List data = [
    "Line:", pln, 
    "\n\nLat:", lat,
    "\n\nLong:", long,
    ];

It prints like

[Line:, P1,
Lat:, x.xxxxx,
Long:, x.xxxxx]

The characters necessary to construct my List such as [] and ,are not wanted in the final print and I can't get rid of them.

I only want the characters within the quotemarks, such as from [Line:, P1, I just want Line: value, but without the other characters the List function won't work.

Thank you

Update

It is used as metadata and added to a map marker, which expands a pop-up upon clicking and shows this data as a list with \n\n adding a new line break

metadata.setString("key_poi", data.toString());

mapScene.addMapMarker(mapMarker);

CodePudding user response：

You don't provide the code, but I guess you're doing this:

print(data);

data is a list, so it's printing the list.

What you probably want to do is convert the list to a String - by joining each element of the list to the other. There's a function for that - join - so try this:

print(data.join());

Note join can take a separator argument - and you can probably use it to get rid of those ugly \n's you have in your code.

In fact, I'd probably do this instead:

List data = [
 "Line: $pln", 
 "Lat: $lat",
 "Long: $long",
];
print(data.join("\n\n"));
