Hey all. I'll make this quick. I want to search for a pattern and replace it with an empty string using the boost/curl libraries OR strictly c++.. No DotNet.
The below code I have, removes HTML Tags from a file/string:
static string StripTags(string source)
{
int iSize = (int)source.length();
char StrData[iSize];
int arrayIndex = 0;
bool inside = false;
for (int i = 0; i < iSize; i++)
{
char let = source[i];
if (let == '<')
{
inside = true;
continue;
}
if (let == '>')
{
inside = false;
continue;
}
if (!inside)
{
StrData[arrayIndex] = let;
arrayIndex++;
}
}
return StrData;
//return new string(StrData, 0, arrayIndex); //DOES NOT WORK?! Don't know why..
}But that leaves HUGE white spaces in the file where the HTML tags were..
Then I tried this, but got stuck because the code I had previously never worked even though it said pattern found.. It also said "Ran out of stack space..":
string preg_match_all(const string WebData)
{
boost::regex expression("<(.|\n)*?>");
try
{
if(boost::regex_match(WebData, expression))
{
cout<<"Match Found.. Replacing with Empty String";
boost::regex_replace(WebData, expression, "");
}
else
cout<<"Match Not Found";
}
catch(exception &e)
{
cout<<e.what();
}
return WebData;
}The PHP Code I'm trying to emulate with C++...
preg_match_all("|<td(.*)</td>|U",$table,$rows);
foreach ($rows[0] as $row){
if ((strpos($row,'<th')===false)){
preg_match_all("|<td(.*)</td>|U",$row,$cells);
$number = strip_tags($cells[0][0]);
