  • 0

I need help to parse some information from a mass of text, basically I am importing a PSD file and want to parse some data from it.

Amongst the text are strings such as this:

\r\nj78876 RANDOM TEXT STRINGS 75 £

Now what I want to do is grab all strings that fit this format (maybe the starting “\r\n” and ending “£” can be delimiters) and get the code at the start (j78876) and the price at the end (75). Note price may be more digits that 2.

I want to then grab the code such as j78876 and the price for each string like this which is found as they will occur many times (different codes and prices).

Can anyone suggest a way to do this?

I am not very proficient with Regex so guidance would be great.

thanks.

Note: Here is a snipped of the actual text (there is a lot more in the actual file).

Update
I found this:

[\\r\\n](\w\d+\w).*?(\d+,\d\d)[\\r\\n]

Worked for me in regex browser testers but will not work in my C# code

Regex reg = new Regex(@"[\\r\\n](\w\d+\w).*?(\d+,\d\d)[\\r\\n]", RegexOptions.IgnoreCase);
Match matched = reg.Match(str);
if (matched.Success)
{
    string code = matched.Groups[1].Value;
    string currencyAmt = matched.Groups[2].Value;
}

Final Update:
In the browser testers i had to double escape the \r\n – in my code it was not necessary. Then to loop the groups I used the looping answer.

foreach (Match match in Regex.Matches(content, @"[\r\n](?<code>\w\d+\w).*?(?<price>\d+,\d\d)[\r\n]", RegexOptions.IgnoreCase))
{
    string code = match.Groups["code"].Value;
    string currencyAmt = match.Groups["price"].Value;
}

    I would use named groups to identify the groups easier. The ?<code> part of the expression identifies the group.

    You will want to use Matches, as you say there will be several occurrences of the pattern in your text. This will loop through them all..

    foreach ( Match match in Regex.Matches(text, @"\r\n(?<code>\S+).*?(?<price>\d+)£") )
{
    string code = match.Groups["code"].Value;
    string currencyAmt = match.Groups["price"].Value;
    Console.WriteLine(code);
    Console.WriteLine(currencyAmt);
}
