## 安装 ##

pugixml Git下载地址：[https://github.com/zeux/pugixml][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/pugiconfig.hpp
    -- 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][Link 1]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
    总用量 340
    -rw-r--r--. 1 root root     95 11月 22 18:07 input.xml
    -rwxr-xr-x. 1 root root 338744 11月 22 19:20 test_pugixml
    -rw-r--r--. 1 root root    615 11月 22 19:20 test_pugixml.cpp
    [root@localhost pugixml_demo]# ./test_pugixml
    parse result:
    192.168.1.2
    50000
    keyvalue
