正则表达式只获取双引号和单引号内的文本以及行号

Question

Regex to get the text within the double and single quotes with line number.

For example:

line 123 Processing File "This is what i am looking for"<'this is also what i need'>

Output should be:

line 123 This is what i am looking for  this is also what i need

My regex is:

 MatchCollection matches2 = Regex.Matches(l, "\"([^\"]*)\"");

     foreach (Match match2 in matches2)
           {
                foreach (Capture capture2 in match2.Captures)
                    {
                        textBox4.Text = textBox4.Text + capture2.Value + Environment.NewLine;

                    }
            }

I am getting (my output):

"This is what i am looking for"

I don't need the double quotes, I need only the text within the quotes.

Answer 1

The first issue here is that you are looking at the match rather than the captures. The captures will show you the stuff gathered by the ( ) operators.

matches2.OfType<Match>().Select(x => x.Captures[0].Value)

Answer 2

尝试这个：

Regex.Replace(inputtext, @"line (\d+).*?\""(.*?)""\W+(.*?)'", "line $1 $2 $3")

Answer 3

string input =
    "line 123 Processing File \"This is what i am looking for\"<'this is also what i need'>";
string output =
    string.Join(" ", Regex.Matches(input, @"(line\s+(\d+)|(""|').*?\3)")
                          .Cast<Match>()
                          .Select(m => Regex.Replace(m.Value,
                                                     @"^[""']|[""']$", "")));

Output:

line 123 This is what i am looking for this is also what i need
