If I get an error message like this:

[XPST0003] Incomplete 'let' expression.

How can I find out more information regarding the error eg. the name of the function that failed? The error message doesn't give any clue about where the error occurred.

I'm using PHP. My code is based on the example code supplied with BaseX.

<?php

include("BaseXClient.php");

$CMD_OPEN = "open cgd-dat"; // BaseX command to open the database.

$xq = "xquery ... a long xquery"; // BaseX xquery command.

try {

$session = new Session("localhost", 1984, "admin", "admin");

$session->execute($CMD_OPEN);

print $session->execute($xq);

$session->close();

} catch (Exception $e) {

print $e->getMessage();

}

?>
