how to write regex to detect end of line??

I am using simple script for reading the LOG file line by line. I need to detect end of line what is \r\n (because windows). Now my LOG message ends with this: "bla bla bla.. status: OK, errors: {}...

    I've had to mess around with regex and ReadyAPI and escaping escape characters. It gets really tricky, but I can show you an example I've been working with: 

     

    Here is a standard regex pattern:

    [A-Za-z0-9\.,\(\)\-\+@\?:\s]*

    To make this work in ReadyAPI / groovy, I have to escape it to look like this:

    [A-Za-z0-9\\.,\\(\\)\\-\\+@\\?:\\s]

    I am taking a look at your example line and match pattern and will see if I can figure it out. Can you potentially provide a copy of the log file you are trying to parse? It'll be easier to work with what you have, or a mocked up file of what you need to process. That way I'm working with the closest thing possible to the source.

    YES.. !!!! :-D

    Why this simple help is not a part of your user guide? I did not found any information about escaping by "\\" nowhere.

    It works!

    I can write simple regex to detect quotes like "\\{\\}" and it matches.

    SO I KNOW, that in between { and } is nothing.. so no problem.

    I can write simple regex to check if end of line is present:

    line.eachMatch("SUCCESS,\\{\\}\\Z")

     

    Thanks a lot. 

    PS: please add this usefull thing in to your WIKI pages.. where your are explaining RegExp in groovy.. will be nice to know.

Hey vikititor,

Im responding cos noone else has yet. I cant help with the groovy per se, but i can probably help with the regex.

You state "in normal regex tester" your regex works but not in ReadyAPI!.
can you explain what you mean by "doesnt work in ReadyAPI!"?
Can you provide the logs for your regex attempts please?
Are you saying youre attempting to escape the metacharacters (e.g. $, {, etc.) So they behave as literals but this isnt working?

Cheers,

Rich

I hope, this is with details.. 

Simpy:

I need to know, if inside of "{}" is nothing.. 

OR

I need to know, that after "SUCCESS,.." is end of line. Because I am unable to escape "{}" in RegEx.. then I was replaced them by "..". BUT, Problem is, that when some error is in there like "{some error}" the regex "SUCCESS,.." will pass.. MEANS.. this is positive FAILS..  In the end.. I dont know nothing..

Nothing works under ReadyAPI..
