stripping from string

[ventos]

First of all, ive been trying to learn c++ for a couple of days ;)

Problem i need to strip http links from string

code:

string replaceAll(string s, string f, string r) {
unsigned int found = s.find(f);
while(found != string::npos) {
s.replace(found, f.length(), r);
found = s.find(f);
}
return s;
}

string stripHTMLTags(string s) {
while(true) {
unsigned int left = s.find('<');
unsigned int right = s.find('>');
if(left==string::npos || right==string::npos)
break;
s = s.erase(left, right - left + 1);
}
s = replaceAll(s, "&lt;", "<");
s = replaceAll(s, "&gt;", ">");
s = replaceAll(s, "&amp;", "&");
s = replaceAll(s, "&nbsp;", " ");
// Etc...
return s;
}


if i try to change

unsigned int left = s.find('<');

to

unsigned int left = s.find('http:');

i get this error: warning: character constant too long for its type

Which must be due to int contains one byte??

unsigned int left = s.find('http:');

More or less although I believe character constants actually have type char in C++. Single quotes indicate a character constant so you can unly have a single character between them. If you wish to us a string use double quotes

unsigned int left = s.find("http:");

thanks. your solution worked. script compiles now as supposed.

My approach to the problem however wasn't correct. It seems this would only work as long as the target string only had one http link in it.

Ill have to rethink my strategy ;)
