JavaScript: Get Message from Data

It looks like you're trying to use javascript to parse a object dumped from PHP.
If so, the correct way is to use PHP's json_encode() function and then you can use javascript's JSON.parse() to get the values.

Thanks, but that won't work because the data is actually coming through a compiled script that I don't have access to.  I need to use REGEX for this.

Something like this

// ASSUMES DATA IS IN data. SPLIT INTO LINES
var newmsg = data.split("\n");
// ARRAY FOR RESULTS
var results = [];

// LOOP THROUGH LINES
for(var i = 0; i< newmsg.length; i++) {
  // TRY TO MATCH MESSAGE LINE - ADD TO RESULT IF MATCHED
  if (match = newmsg[i].match(/\[Message\] => (.*)/)) {
    // ADD FIRST MATCHED SUBSTRING TO ARRAY
    results.push(match[1]);
  }
}
console.log(results);

Isn't there a simpler way to do this?  My code  below ALMOST works.  It stops at the next "u" but I want it to stop at the next newline.

var data = 'stdClass Object\
(\
    [HighestSeverity] => ERROR\
    [Notifications] => Array\
        (\
            [0] => stdClass Object\
                (\
                    [Severity] => ERROR\
                    [Source] => ship\
                    [Code] => 3058\
                    [Message] => Recipient Postal code required\
                    [LocalizedMessage] => Recipient Postal code or routing code is required\
                )\
            [1] => stdClass Object\
                (\
                    [Severity] => ERROR\
                    [Source] => ship\
                    [Code] => 3431\
                    [Message] => International Importer of Record Required\
                    [LocalizedMessage] => International Importer of Record - Postal code or routing code is required\
                )\
\
        )\
)';


alert( data.match(  /\[Message\](\s)?=>(.[^u]+)/ )[2]  );

You would need to use RegExp to find multiple instances

// The regular expression
var re = /\[Message\]\s*?\=\>\s*(.*)/g;
// Results array
var results = [];
var match;
// Keep matching till all done
while((match = re.exec(data)) !== null) {
   results.push(match[1]);
}

Not much simpler than the other solution...

I only want the first match.  I don't want an array.  Only the first  [Message] should be returned.

Thanks for all your help with this but it still is not working.  Please test this, thanks.

                )\

var re = /\[Message\]\s*?\=\>\s*(.*)/;
alert(data.match(re)[1]);

This all depends how you are going to get your data. Your text data above is effectively one long line - the continuation character '\' cancels out the CR so the regex is matching to the end of the data
So we need to break the search. There are many ways we can do that.

1. By looking for more than one space next to each other

var re = /\[Message\]\s*?\=\>\s*(.*?)\s\s+/;
var match = data.match(re);
console.log(match[1]);

2. By looking for an opening '[' and triming the result

var re = /\[Message\]\s*?\=\>\s*(.[^\[]*)/;
var match = data.match(re);
console.log(match[1].trim());

However you need to consider where your data is ultimately going to be coming from - if it is from a source where there will be '\n' delimited lines then the original solution would apply - the above would not work.

Thanks for pointing that out!  Your previous solution works when used with my real data.

Glad to help.
