安装

pugixml Git下载地址：https://github.com/zeux/pugixml

步骤1：首先，你需要下载pugixml 的源代码。你可以从Github或者源代码官方网站下载。并上传至/usr/local/source_code/ 

步骤2：下载完成后，需要将源代码解压，可以使用以下命令：

 tar -zxvf pugixml-1.13.tar.gz

 步骤3：解压后，切换到源代码目录：

[root@localhost source_code]# cd pugixml-1.13

 步骤4：生成pugixml 静态库，执行如下指令：

mkdir build
cd build
cmake ..
make && make install

[root@localhost build]# cd ..
[root@localhost pugixml-1.13]# cmake .

-- Up-to-date: /usr/local/include/pugixml.hpp

 温馨提示：完成以上步骤后，在/usr/local/lib下会生成libpugixml.so动态库和/usr/local/include下生成pugixml.hpp头文件。你可以使用以下命令查看是否安装成功：

ls /usr/local/lib | grep pugixml
ls /usr/local/include | grep pugixml

如果看到，则说明成功安装了pugixml库 .

快速入门

在/usr/local/source_code 新增pugixml_demo 目录并新增test_pugixml.cpp 文件，文件内容如下：

#include "pugixml.hpp"
#include <iostream>
using namespace std;int main(){pugi::xml_document doc;pugi::xml_parse_result result = doc.load_file("input.xml");if(!result)return -1;cout << "parse result: " << endl;pugi::xml_node root_node = doc.child("platform");pugi::xml_node ip_node = root_node.child("ip");pugi::xml_node port_node = root_node.child("port");pugi::xml_node key_node = root_node.child("key");cout << ip_node.text().as_string() << endl;cout << port_node.text().as_int() << endl;cout << key_node.text().as_string() << endl;return 0;
}

在test_pugixml.cpp 文件所在目录新增input.xml 文件，文件内容如下:

<platform><ip>192.168.1.2</ip><port>50000</port><key>keyvalue</key>
</platform>

编译源码并执行：

[root@localhost pugixml_demo]# g++ test_pugixml.cpp -o test_pugixml -std=c++11 -lpugixml
[root@localhost pugixml_demo]# ll
