Rex Exp

I want to rex the following string out of a paragraph:

[ss33] [Mess. Privato] [Home Page] [Cerca Mess.] [Aggiungi Amico] [Modifica Mess.] [Quota e Rispondi]

I coudn't get it all working, I got only the first part "[ss333]" but I coudn't get the rest of the string by using:

<rex ">>=\[=\alnum*\]+" $stringValue>

how could I repeat the whole rex for the rest of the string or is there any other way to do it.....

$ret should have contained all occurrences in separate elements, so

<loop $ret>
$ret
</loop>

would have shown them. To concatenate them again you
could use <sum %s '' $ret>

All the other items also have space in them and some have "." not just alnum. Use a set with all the required characters. And your ">>=" should be just ">>".

I got it working by using
">>=\n*\space*\[=\print+\n+"
as I would like it to match only the first line of the paragraph.

thx.

Oh, an entirely different set of requirements...

\n*\space* can be simplified to \space* since \n is included in \space.

Depending on requirements I might change \print to [^\n] in case there happens to be some non-printables and I wanted the whole line.

>>=\space*\[=[^\n]+\n+
