[Boost-users] Regex problem

12 Mar 2008

      Hi everyone,

I'm trying to parse an HTML page using the Regex library and am  
running in to errors.

In the following snippets, "pageSource" is a string pointer to the  
contents of an html file.

This code causes my app to crash:

void Page::removeScriptTags() {
	boost::regex tagRegex("<[sS][cC][rR][iI][pP][tT][\\w\\W]*?>[.]*?");
	string replaced = boost::regex_replace(*pageSource, pageSource,  
tagRegex, " ", boost::match_default);
	delete pageSource;
	pageSource = new string(replaced);
}

and this code crashes when attempting to destruct "matches":

void Page::findTitleSummary() {
	boost::cmatch matches;
	boost::regex bodyRegex("<[tT][iI][tT][lL][eE][\\w\\W]*?>([^<]*)");
	if (boost::regex_search(pageSource->c_str(), matches, bodyRegex)) {
		pageSummary = new string(matches[1]);
		hasFoundSummary = true;
	}
}

What am I missing?

Thanks,

Dave
