Processing Semicolon

Why I can't use regexreplace or trim on semicolon?

Examples where it doesn't work?

Sure.

Code: Select all

   $tk = "(test);";
// step;
   $tk = regexreplace("$tk", "chr(59)", ""); //otherwise regexmatches will bitch...
   $tk = trim("$tk", eval("chr(59)")); //otherwise regexmatches will bitch...
   $tk = trim("$tk", "*;(+)."); //otherwise regexmatches will bitch...
   text "no semicolon here?<crlf>$tk";

No clue what you're talking about...

Code: Select all

    $tk = "(test);";
    $tk = regexreplace($tk, ";");
    text $tk;

    $tk = "(test);";
    $tk = trim($tk, ";");
    text $tk;
"*;(+)."
What's that, a regex pattern?

So it seems I don't understand quoting too.

Removing quotes on "$tk" makes it work.

No. Those characters, perhaps more, if present on input make regexmatches throw error messages for each time they happen on a loop. Anyway I'm considering asking a silent mode for cases like these.

Thanks very much for your assistance, highend! Soon I'll post the entire script on a new post per your instructions so you can check what improvements can be made, as you suggested on the thanks thread ("I bet that can be done faster xD").

I really cant take it.

Now it's not working again:

Code: Select all

   $tk = "(te);";
 step;
   $tk = regexreplace($tk, "chr(59)", ""); //otherwise regexmatches will bitch...
   $tk = trim($tk, eval("chr(59)")); //otherwise regexmatches will bitch...
   $tk = trim("$tk", "*;(+)."); //otherwise regexmatches will bitch...
   text "no semicolon here?<crlf>$tk";
Got it.
If copied from forum, it works.
Will attach it in a few secs...

Ehm, removing of quotes around $tk has what to do with this case?
This is just unnecessary quoting, that's all.

Code: Select all

$tk = regexreplace("$tk", "chr(59)", "");
This is crap. You're quoting a scripting command which makes it a string, not a command.
make regexmatches throw error messages
These are special characters. They need to be escaped in a regex pattern. A semicolon isn't one of them^^

It's a trick problem. If you bother...

Go here:
http://www1.folha.uol.com.br/mercado/20 ... agem.shtml

Put the text in print preview, copy the whole page;

Paste the content on a notepad window;

Locate "(SP);" on it, copy it and use it as source for "$tk" variable at the posted script (any version).

-regexreplace and trim will not process it!

I agree.

How do you do the measurement???

Code: Select all

    $start = now("msecs");

... code to execute ...

    $duration = now("msecs") - $start;
    text $duration . " msecs";

What?
I insert it right into the Run Script dialogue. Once done coding, then I paste both code and processed text into plain text files.

What you're trying to do here is asking the script to match the string "chr(59)" in $tk. This could've worked if $tk = "I have chr(59) within me"; . You should not quote function calls when you want to use their return. Use them like this: $v = "prefix" . function() . "suffix";
Anyway, chr() is not needed at all. You can just do

Code: Select all

   $tk = regexreplace($tk, ";", "");
   $tk = trim($tk, ";");
This is the FIRST thing you should've tried, before all that eval(), chr() business. :maf:

Not so fast, pal, not so fast!
I did started with simple'r versions. As they proved to be useless on the input described above I started experimenting.
Try to use the attached zipped .txt as source, thus avoiding the complicated steps I described, and perhaps you can see for yourself.

You said you want to extract the (SP); part and trim it, but since this is already a known static string, there doesn't seem much need for scripting.
How exactly do you want to process that attached text?
