HtmlTools package for U++
type: item
description: Hi, I am happy to announce that U++ is about to gain something U++ users have been long missing: Aa very powerful html parser/sanitizer/prettifer: HtmlTools package. This package is basically a libtidy bindings/wrapper, bringing the power and performance of one of the oldest and widely used html library to U++. You can find the initial version of the source and example code here. DONE: + Implemented HtmlNode class. (A modification of Upp::XmlNode class) + Implemented TidyHtmlParser, TidyHtmlParser::Node classes for traversing the document tree. + Implemented ParseHtml and RepairHtml convenience functions. + Added a minimal code example, parsing the legacy example.com. TODO: - Enable U++'s memory managers in libtidy. - Add U++ callbacks for libtidy's message queue. - Refactor buffer allocation code. - Add Topic++ documentation. - Add more example code (both console & gui). - Test the Windows build. - Cosmetics. The base example, downloading and parsing the example.com #include <Core/Core.h> #include <Core/SSL/SSL.h> #include <HtmlTools/HtmlTools.h> using namespace Upp; void PrintHtml(const HtmlNode& node) { for(const HtmlNode& q : node) { if(q.IsTag("title")) Cout() << q.GatherText(); else if(q.IsTag("p")) Cout() << q.GatherText(); else if(q.IsTag("a")) Cout() << "For more information, see: " << q.Attr(0) << EOL; PrintHtml(q); } } CONSOLE_APP_MAIN { StdLogSetup(LOG_FILE); HtmlNode n = ParseHtml( HttpRequest("https://example.com/").Execute(), { { "wrap", 96 } }); // libtidy options... PrintHtml(n); } Note that the package is still experimental. Feedbacks are welcome. Enjoy! Best regards, Oblivion

description: Hi, I tried to make something similar a couple of months ago, i was aiming for a web scraping plugin like Beautiful Soup. I managed to show amazon.com on XmlView but my code was such a miss i never got the courage to publish it. Thank you very much Oblivion for this package.
