parsing mozilla's Error stack property

[Java script Dude]

Has anybody hacked a stack parser for Mozilla Error stack property.

Some basic regular expressions would work well, but my time is a little
tight of late.

Basically I would like to parse out, function/method name, source path,
source name, line number.

Thanks,
JsD

try
{
// don't declare x before
y = x;
}
catch (e)
{
var m, a = [];
while ((m = /^\s*(.*)@(.+)\d+)\s*$/gm.exec(e.stack)))
{
a.push("Call: " + m[1] + "; source: " + m[2] + "; line: " + m[3]);
}
window.alert(e.stack + "\n__\n" + a.length + "\n__\n" + a.join("\n"));
}

Separating function identifier from argument list, and source path from
source name, is left as an exercise to the reader.

try
{
// don't declare x before
y = x;
}
catch (e)
{
var m, a = [];
while ((m = /^\s*(.*)@(.+)\d+)\s*$/gm.exec(e.stack)))

As I see that the source is also optional, this should be changed to

while ((m = /^\s*(.*)@(.*)\d+)\s*$/gm.exec(e.stack)))
