c# Extract sentences using Regular expression

Related searches

First of all sorry if this question has been asked several times but I can't figure out how to solve it even after checking the existing answers. I'm new with Regexp and what I'm trying to do is to extract the sentence(s) between the double quotes after the string "Translate" knowing that the latter string may appear several unknown times and the sentence between the doubles quotes can contain digits and special characters.

For example, with the expression below:

'RadMessageBox.Show(Translate("Problem with arguments"), Translate("Error!"), Translate("Bad digital format, it must be of the form 112.3456E12."), MessageBoxButtons.OK, RadMessageIcon.Error);'

I would have:

'Problem with arguments      Error!      Bad digital format, it must be of the form 112.3456E12.'

Dot NET Regex: @"Translate\(""([^""]+)", next you should join results.

C# Regex.Match Examples: Regular Expressions, Digits: We extract a group of digit characters and access the Value string representation of that number. Parse: To parse the number, use int.Parse or int. TryParse� Regular expressions in C# are defined within the System.Text.RegularExpressions namespace which provides a Regex class. When instantiating the class you need to pass the expression string to the constructor. We have used a verbatim string for the regex as it makes the regex easier if you don't have to escape forward slashes.

The following would give you the strings, including the quotation marks: "[^["]*.]*.

If you wanna remove them, you can use a simple string.Split('"')

Regular expressions are built into tools including grep and sed,text editors including vi and emacs, programming languages including C#, Java,and Python. C# has built-in API for working with regular expressions; it is located inSystem.Text.RegularExpressions. A regular expression defines a search pattern for strings.

const string sent = "RadMessageBox.Show(Translate(\"Problem with arguments\"), Translate(\"Error!\"), Translate(\"Bad digital format, it must be of the form 112.3456E12.\"), MessageBoxButtons.OK, RadMessageIcon.Error);";
const string pattern = "([\"'])(?:\\1|.)*?\\1";

var results = Regex.Matches(sent, pattern);
var sb = new StringBuilder();

foreach (var match in results)
{
    sb.Append(match.ToString().Trim('"') + " ");
}

Console.WriteLine(sb.ToString());

If I understood the question correctly, that's a working example

By instantiating a Regex object that represents the regular expression. To do this, you pass the regular expression pattern to a Regex constructor. A Regex object is immutable; when you instantiate a Regex object with a regular expression, that object's regular expression cannot be changed.

Often, grouping constructs are used in a regular expression only so that quantifiers can be applied to them, and the groups captured by these subexpressions are not subsequently used. For example, the regular expression \b(\w+[;,]?\s?)+[.?!] is designed to capture an entire sentence.

  • Translate is not a string. It's a method you're calling
  • The text you posted looks like code. Are you looking for a regex to extract the strings between the quotes from your source code files? Or are you trying to change the behavior of the running program?
  • Ofc it has since I'm trying to extract the sentences using Regex...
  • Totally Cid, Translate is a method
  • Yes gnud, it's a code and I'm looking for a regex to extract the strings between the quotes from my source code
  • That works fine @crankedrelic thank you ! Can you plz describe how did you compose the pattern ?
  • You 're welcome. Have a look here blog.stevenlevithan.com/archives/match-quoted-string
  • As you 'll see you can edit the pattern by removing ' , to only match double quotes
  • Correct me if I'm wrong but that pattern will substring whatever sentences or characters between doubles quotes. However if I have something like this (see below), it's not going to get me only sentences given to my Translate method: msgerror += Translate(" The symbol used below the named symbol") + " \"" + symbol.name + "\"" + Translate(", row") + (symbol.row + 1) + Translate(" column ") + (symbol.column + 1) + Translate(", is not correct.") + "\n"; Can you tell me what pattern should I use in that case plz ?
