Capturing text between two words with Regex

[ffreino]

Hi,
I'm trying to capture text between two words in a multi-line string.
For example:
89. This is the text I would like to capture.
This is another line.
90. End of the example.

I would like to capture text between the words (numbers in this case)
'89' and '90'

Any ideas?
Thanks in advance.

did not test in code but try this:
string ResultString = null;
try {
ResultString = Regex.Match(Sub jectString, "(?<=89)[a-zA-Z\\.
\\r\\n0-9]*(?=90)").Value ;
} catch (ArgumentExcept ion ex) {
//error
}
you can replace 89 and 90 with whatever your two words are
if there are other special characters that show up in between you need to
place them in the [] brakets.
hope this get's you started at least...

The Regex to do that needs to specify a group to be captured and also allow
multiline captures.

Try this

Regex MyRegex = new
Regex(@"89(?<Gr oupToCapture>.* )90,RegexOption s.SingleLine);
//The parentheses define a group and the ?<name it.
//The option selected allows ".*" to match across multiple lines

MyRegex.Match(M ytext).Groups["GroupToCapture "].Value
I am pretty sure that is correct, but I did it from memory, so my syntax may
be off a little in the line to retrieve the group. I am almost certain the
Regex is correct.

Regex(@"89(?<Gr oupToCapture>.* )90,RegexOption s.SingleLine);

You have to be careful with .*, since it's "greedy". It will grab all the
rest of the characters in the target text, including any "90"s it sees.

You need to use .*? to make the search nongreedy:

89(?<GroupToCap ture>.*?)90

Thanks a lot.
I wanted to capture questions from a text exam. The exam has this
format:
1. First question
a. Answer number one
b. Answer number two
2. Second question
a. ...
b. ...
And so on...
I didn't understand very well the meaning of (?<=...) but now I think
It's like an anchor, isn't it?
I also had problems with the greedy . as Mark Wilden pointed out.

Finally, this is the pattern to capture the questions (?<=\d+)(.+?)(? =
\d+) with the RegexOptions.Si ngleLine of the text exam.

Thanks.

There is a problem with the pattern (?<=\d+)(.+?)(? =\d+)
I can't capture question number because group(0) it's only the '(.+?)'
part. The first part of the pattern '(?<=\d+)' it is not capturing.
How can I capture, the question number?
Thanks a lot.

Ok.
I have tried this pattern (\d+)\.\s+(.+?) \s+(?=\d+\.) with
RegexOptions.Si ngleline and it works perfectly.
Thanks a lot
