Maria:

Try

data4 = {{"050318", "00111529"}, {"050401", "00113120"}};
 Do[
 ID = data4[[i, 2]];
 url = "http://www.swift.ac.uk/xrt_curves/"; <> ID ;
 s = Import[url, "Text"];
 Print[s],
 {i, 1, Length[data4]}
 ]

The string join you were attempting did not work. I moved the concatenation
of the url string external to the Import this way if you wish to test if the
url exist before import you can. Somewhere on MathGroup there is code to
test for existence of a URL.

Dear Math Group,

I have a problem importing the data from a web page.

data4 = {{"050318", "00111529"}, {"050401", "00113120"}}
Do[
 ID = data4[[i, 2]];
 s = Import["http://www.swift.ac.uk/xrt_curves/<>ID<>", "Text"];
 Print[s],
 {i, 1, Length[data4]}]

The error message is
$Failed

I am really grateful if you could help me

Best regards,
Maria
