Removing strings from html files

Question

In my project I need to read the contents of an HTML file as said in that question of mine. What happens is I can scan the file, but there’s a comment I wanted to take out.

The peculiarity is that this comment is always changeable, so how can I get c# to remove all the code snippets that appear ?

The comment that appears is this one:

<!-- saved from url=(0103)https://sistema.registrocivil.org.br/buscas/certidoes2aViaGerarXmlBusca.cfm?pedido_certidao_id= -->

Is there any way I can get these comment elements out of HTML(<!---->) and everything that’s inside that element ? Because it’s always changeable, you can’t use Replace and take.

I wonder if someone could help me ?

Answer 1

You can remove comments using Regex, as follows:

string semComentarios = Regex.Replace(stringHtml, @"<!--(.*?)-->", String.Empty);

See an example working in that fiddle.

Answer 2

Do the following :

    int indexIni = 0;
    int indexFim = 0;
    string html = @"<div> dfklçbndflçbndfblçdfnmblçdfmblçdfmblçdmfblçdfbmç<!-- saved from url=(0103)https://sistema.registrocivil.org.br/buscas/certidoes2aViaGerarXmlBusca.cfm?pedido_certidao_id=21716443 --></div>";

    Console.Write(html);

    indexIni = html.IndexOf("<!--");

    indexFim = html.IndexOf("-->");

    if (indexIni != -1 && indexFim != -1)
    {
        html = html.Remove(indexIni, Math.Abs(indexIni - (indexFim + 3)));
    }

    Console.Write(html);
