Text analysis in Azure Logic applications

Question

I want to create an Azure Logic App that will constantly query a specific site on the Internet and analyze the resulting HTML.

I created the Logic App and configured the interval and action of the HTTP request.

What action should be taken as the next step for a simple regex operation in HTML?

What comes to my mind is creating an Azure Function that will do the job, but I wonder if there is another solution that is more suitable for such a task.

I want it to be as simple as possible.

Edit:

Just found out some interesting feature. Logic applications contain some basic expressions for primitive types.

, regex string.contains.

Azure.

Answer 2

Azure Function :

{

log.Info( " # ".);

// Get request body

dynamic data = await req.Content.ReadAsAsync<object>();



// Set name to query string or body data

string input = data?.input.ToString();

var regexJson = data?.regexList;

var regexes = regexJson.ToObject<List<RegexReplace>>();



foreach (var regex in regexes) 

{

    var re = Regex.Replace(regex.Regex, "\\\\","\\");

    var replace = Regex.Replace(regex.Replace, "\\\\","\\");

    input = Regex.Replace(input, "\\\"","\"");

    input = Regex.Replace(input, re, replace);

}



input = Regex.Replace(input, "[\\r\\n]", "");



return data.regexList == null

    ? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")

    : req.CreateResponse(HttpStatusCode.OK, input, "application/json");

}

public class RegexReplace

{

public string Regex { get; set; }

public string Replace { get; set; }

}

    dynamic data = await req.Content.ReadAsAsync<object>();
    string removeme = data?.removeme;
    string replacewith = data?.replacewith;
    string value = data?.value;

    return req.CreateResponse(HttpStatusCode.OK, value.Replace(removeme, replacewith));
