does istream can be used with some kind of regular expression to read files. Html file I just like to search and replace some inner data in tags

Question

I have a simple ifstream code for reading a html file.

#include <fstream>
#include <iostream>
using namespace std;
 
int main () {
    char data[100];

    //open a file in read mode.
    ifstream infile; 
    infile.open("html9.html"); 
    while(infile >> data)
        cout << data << endl;

    infile.close();

   return 0;
}

Basically I like to search for tr tag followed by search for td tag then replace whatever inside the td tag with my own data. My html table tag is like this

            <table>
              <tr>
                <td>
                  #Title    
                </td>
                <td>
                  #Info
                </td>
                <tr>
                  <td></td>
                </tr>
              </tr>
            </table>

The html can be large file so my table tag will eventually require some searching. I need the flexibility of regex so I like to know can I use some sort of regex with istream object (istream is only which I like to use).

Sorry if I jumped right into requiring some example code and some explanation about istream and embedding regex with it but I really couldn't find any place on internet where I can also find this with example and step by step explanation.
