getting arguments withn RegEx please help

[matro]

hi there,

I'm using RegEx object with the string "(\[.*?\])" to get arguments
from a line like this:

This line has got [one] argument and [another] one.

the issue is that I obtain a MathCollection with "[one]" and
"[another]".

how can I modify the pattern string to have [ and ] stripped so to get
"one" and "another"?

please help!
thank you.

Hi,

You can do this with one match, like:

using System.Text.RegularExpressions;

Match m =
Regex.Match (strInput, "(?:.*?\\[(?'key'\\w*?)\\])*" );

// print all keys in string that are between [ ]
foreach (Capture c in m.Groups["key"].Captures)
{
System.Console.Write (c.ToString() + "\r\n" );
}

HTH
greetings

Jhon already answered this but instead of writing out the code I thought you
should know what is happening here. First, you're getting "[one]" instead
of "one" because your parentheses are requesting the brackets. If your
regexp was "\[(.*?)\]" you'd trim that off.

Also, the "." matches any character except newline, so if you only want a-z,
you could use \w, otherwise you might match spaces between those brackets,
which may or may not be what you want.

The "?" at the end tells the regular expression to stop as soon as it can
and still match, so it won't match the right bracket as part of the "."
match.
