How do I search for a text in a string and grab everything after the search text until it reaches a character?

Question

I am searching a huge html document on the web that will have multiple instances of names. Each section throughout the page source will contain something like this

{"keyword_text":"kathy smith","item_logging_id":"2021-05-16:yakMrD","item_logging_info":"{"source":"entity_bootstrap_connected_user_suggestion",{"keyword_text":"courtney lee","item_logging_id":"2021-05-16:lX1LC2","item_logging_info":"{"source":"entity_bootstrap_connected_user_suggestion",

I want to grab all the names in the source and put them into a text box.

Search the string for "keyword_text":" then grab all text after until it reaches " excluding the "

I want the end result to be

kathy smith

courtney lee

Answer 1

Considering the "until it reaches the character" you can use the regex ([^\"]*)

^ means NOT and * means multiple times. So it reads everything until the first appearance of " . The \ is to escape the quotes.

So in your case this is the regex: \"keyword_text\":\"([^\"]*) to get the name-part without quotes.

And in c# context:

var matches= new Regex("\"keyword_text\":\"([^\"]*)").Matches(yourInputText);

foreach (Match match in matches)
{
    Console.WriteLine(match.Groups[1].Value);
}

Answer 2

string str = "Would \"you\" like to have responses to your \"questions\" sent to you via email?";
var reg = new Regex("\".*?\"");
var matches = reg.Matches(str);
foreach (var item in matches)
{
   MessageBox.Show(item.ToString());
}
