但是在下载 libxml2-2.6.30.tar.gz 之后安装编译的时候发现问题：

Ubuntu C语言使用 libxml2库读写XML文件

下载新版本 libxml2-2.6.30.tar.gz

http://linux.softpedia.com/get/Programming/Libraries/libxml2-162.shtml#download

./configure

make

sudo make install

新建一个xml文件夹

mkdir xml

新建一个xml 文件:List.xml

<?xml version="1.0"?>
<List>

<Person Id="1001" Name="Tsybius" Sex="Male" Age="23">
    <Achievement>ABC Rank 2

    </Achievement>

    <Achievement>

    DEF Rank 4

    </Achievement>
</Person>


<Person Id="1002" Name="Galatea" Sex="Female" Age="21">

    <Achievement>ABC Rank 1</Achievement>

    <Achievement>XYZ Rank 2</Achievement>

    <Achievement>MNOP Rank 5 </Achievement>

</Person>
</List>
