Replace text in a string between two points

Question

User-1188570427 posted

Hello,

What is the best way to replace text in a string between two points?

Example:

page1|size10|hierarchy21|0|-1|1|-1|2|-1|3|-1|4|-1|5|-1|6|-1|7|-1|8|-1|9|-1|10|-1|11|-1|12|-1|13|-1|14|-1|15|-1|16|-1|17|-1|18|-1|19|-1|20|-1|visible21|t0|t1|t2|t3|f4|f5|f6|f7|f8|f9|f10|f11|f12|f13|f14|f15|f16|f17|f18|f19|f20|width21|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e

I want to replace all "f"s between visible and width with "t"s?

hi

you can use <g class="gr_ gr_4 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" id="4" data-gr-id="4">Regex</g> expression

 var text = "page1|size10|hierarchy21|0|-1|1|-1|2|-1|3|-1|4|-1|5|-1|6|-1|7|-1|8|-1|9|-1|10|-1|11|-1|12|-1|13|-1|14|-1|15|-1|16|-1|17|-1|18|-1|19|-1|20|-1|visible21|t0|t1|t2|t3|f4|f5|f6|f7|f8|f9|f10|f11|f12|f13|f14|f15|f16|f17|f18|f19|f20|width21|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e";
    var pattern = "visible(.*)width21";
    Regex regex = new Regex(pattern);
    var fetch = regex.Match(text);
    string result = fetch.Groups[1].ToString().Replace("f", "t");

    result = Regex.Replace(text, pattern, "visible" + result + "width21");

result

hi

you can use Regex expression

 var text = "page1|size10|hierarchy21|0|-1|1|-1|2|-1|3|-1|4|-1|5|-1|6|-1|7|-1|8|-1|9|-1|10|-1|11|-1|12|-1|13|-1|14|-1|15|-1|16|-1|17|-1|18|-1|19|-1|20|-1|visible21|t0|t1|t2|t3|f4|f5|f6|f7|f8|f9|f10|f11|f12|f13|f14|f15|f16|f17|f18|f19|f20|width21|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e";
    var pattern = "visible(.*)width21";
    Regex regex = new Regex(pattern);
    var fetch = regex.Match(text);
    string result = fetch.Groups[1].ToString().Replace("f", "t");

    result = Regex.Replace(text, pattern, "visible" + result + "width21");

result

befor Replace
page1|size10|hierarchy21|0|-1|1|-1|2|-1|3|-1|4|-1|5|-1|6|-1|7|-1|8|-1|9|-1|10|-1|11|-1|12|-1|13|-1|14|-1|15|-1|16|-1|17|-1|18|-1|19|-1|20|-1|visible21|t0|t1|t2|t3|f4|f5|f6|f7|f8|f9|f10|f11|f12|f13|f14|f15|f16|f17|f18|f19|f20|width21|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e|e

Thanks for the help.

The end of width might be any number though.

If I change the patter to this:

var pattern = "visible(.*)width(.*)";

This is my result:

page1|size10|hierarchy21|0|-1|1|-1|2|-1|3|-1|4|-1|5|-1|6|-1|7|-1|8|-1|9|-1|10|-1|11|-1|12|-1|13|-1|14|-1|15|-1|16|-1|17|-1|18|-1|19|-1|20|-1|21|t0|t1|t2|t3|t4|t5|t6|t7|t8|t9|t10|t11|t12|t13|t14|t15|t16|t17|t18|t19|t20|

It is missing the rest?

Awesome, fixing the pattern and then me adding the code that you updated appears to have given me the results I need. 

YOU ARE AWESOME!
