Question

C++调用pugixml，最后save_file后生成的xml带encoding="utf-8" 怎么修改

要这种效果<?xml version="1.0" encoding="utf-8"?>

实际<?xml version="1.0">

Answer 1

谢谢，我直接改的源码，加上了那句

Answer 2

太粗暴了！！！建议还是用官方的API

Answer 3

官方文档有详细的说明，建议先看文档。

解压后代码目录：

docs/manual.html#saving.declaration

// get a test document
pugi::xml_document doc;
doc.load("<foo bar='baz'><call>hey</call></foo>");

// add a custom declaration node
pugi::xml_node decl = doc.prepend_child(pugi::node_declaration);
decl.append_attribute("version") = "1.0";
decl.append_attribute("encoding") = "UTF-8";
decl.append_attribute("standalone") = "no";

// <?xml version="1.0" encoding="UTF-8" standalone="no"?>
// <foo bar="baz">
//         <call>hey</call>
// </foo>
doc.save(std::cout);
std::cout << std::endl;
