jquery load and parse file

It is the best way (in term of performance) to load and parse a log file
to coloring all "error"?
<div class="mydiv"></div>
$.get(path, function(data) {
var lines = $(data.toString().split(/\n/));
for (var i = 0, len = lines.length; i < len; i++) {
if (lines[i].indexOf("error") >= 0){
lines[i]=lines[i].replace("error", "<span
class='error'>error</span>");
$(".mydiv").append(lines[i]);
}
})
.error {
background-color:red ;
}
