a simple c++ html parser
Chinese Introduction
https://xilixili.net/2017/03/16/htmlparser/
Basic usage please see demo test.cpp.
The compiler must support at least tr1 both Win and GNU/Linux for smart_ptr & unordered_set.
Any c++11 compiler was supported. others may works.
同样是c++做爬虫,解析html
我用的tidy,将html格式化到xhtml
然后就可以xml解析了
The text() method is not handling invalid start tags correctly, resulting in incorrect text output
TEST(test, handlesInvalidStartTags) {
std::string html("<html><div>Hello < There <&></div></html>");
HtmlParser parser;
shared_ptr<HtmlDocument> doc = parser.Parse(html);
std::vector<shared_ptr<HtmlElement>> els = doc->SelectElement("//div");
ASSERT_EQ(1, els.size());
// ASSERT_EQ("Hello < There <&>", els[0]->text());
ASSERT_EQ("Hello ", els[0]->text());
}
The expected value of els[0]->GetValue() is not returned, when handling escaped script, which leads to incorrect parsing.
TEST(test, handlesEscapedScript) {
HtmlParser parser;
shared_ptr<HtmlDocument> doc = parser.Parse("<html><script><!-- one <script>Blah</script> --></script></html>");
vector<shared_ptr<HtmlElement>> els = doc->SelectElement("//script");
ASSERT_EQ(1, els.size());
// <!-- one <script>Blah
// ASSERT_EQ("<!-- one <script>Blah</script> -->", els[0]->GetValue());
}
