Took a look at the code in CNode.cpp and it is so thin a wrapper around GumboNode* that it does not handle the code of a NULL node. It has this problem all throughout the code in that file.
It will have to be rewritten and hardened.
Thanks for the head's up!

Btw, if you try something like this (p:first-child:first-of-type) it gives you a segmentation fault:
Code:
void test_html() {
std::string page = "<html><div class=\"chapter\"><p class=\"flush\">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua</p><p>second child</p></div></html>";
CDocument doc;
doc.parse(page.c_str());
CNode pNode = doc.find(".chapter > p:first-child:first-of-type").nodeAt(0);
std::string content = page.substr(pNode.startPos(), pNode.endPos() - pNode.startPos());
printf("Node: #%s#\n", content.c_str());
}
(Silly example? Absolutely. But what else does one test for. ^_^) |
