How to store entire source of xml file as a string in c++

问题

The xml can only be referred to in the code as an external link for eg. "www.etc.com". I want to be able to extract certain words from the page source of certain websites, but first i need to dump the source content into a string or CString. Thanks for any help

回答1:

I think what you are asking is how to fetch data from the internet. I found this thread and some source code regarding this.

You can use a DOM or SAX parser to retrieve each element.

If you want the entire xml file content in memory, then here is the sample code to make it

 

       ifstream fin("books.xml");

       if ( fin.fail())
          return 1;

       fin.seekg(0, ios::end);
       size_t length = fin.tellg();
       fin.seekg(0, ios::beg);

       char* buffer = new char[length+1];
       fin.read(buffer, length);
       buffer[length] = '\0';

       fin.close();
