[libxml++] looking for XPATH details - get html tag <script with his attributes ...

[Jens K. <jk...@we...>]

Hello,

I found some code on a website (dont remember):
What I want, is, to check for the tag <script src ...>
TIA

int test_html(request_rec *req, char* file)
{
     std::string url = "http://127.0.0.1/";
     curlpp::Easy request;

     // Specify the URL
     request.setOpt(curlpp::options::Url(url));

     // Specify some headers
     std::list<std::string> headers;
     headers.push_back(HEADER_ACCEPT);
     headers.push_back(HEADER_USER_AGENT);
     request.setOpt(new curlpp::options::HttpHeader(headers));
     request.setOpt(new curlpp::options::FollowLocation(true));

     // Configure curlpp to use stream
     std::ostringstream responseStream;
     curlpp::options::WriteStream streamWriter(&responseStream);
     request.setOpt(streamWriter);

     // Collect response
     request.perform();
     std::string re = responseStream.str();

     // Parse HTML and create a DOM tree
     xmlDoc* doc = htmlReadDoc((xmlChar*)re.c_str(), NULL, NULL, 
HTML_PARSE_RECOVER | HTML_PARSE_NOERROR | HTML_PARSE_NOWARNING);

     // Encapsulate raw libxml document in a libxml++ wrapper
     xmlNode* r = xmlDocGetRootElement(doc);
     xmlpp::Element* root = new xmlpp::Element(r);

     std::string xpath = "//html/head/title/text()";
     auto elements = root->find(xpath);

     //std::string ads = "//html/head/"
     // the line below is the crash point
     std::string dstr = 
dynamic_cast<xmlpp::ContentNode*>(elements[0])->get_content();

     ap_rprintf(req,dstr.c_str());
     xmlFreeDoc(doc);

     return OK;
}
