文件里面的内容格式就是这种的。。
<FilmData>
  <FilmCount>4</FilmCount>
  <Film>
  <Title><![CDATA金庸01]]></Title>
  <Director><![CDATA[]]></Director>
  <Actor><![CDATA[]]></Actor>
  </Film>
<Film>
  <Title><![CDATA金庸02]]></Title>
  <Director><![CDATA[]]></Director>
  <Actor><![CDATA[]]></Actor>
  </Film>
<Film>
  <Title><![CDATA金庸03]]></Title>
  <Director><![CDATA[]]></Director>
  <Actor><![CDATA[]]></Actor>
  </Film>
<Film>
  <Title><![CDATA金庸04]]></Title>
  <Director><![CDATA[]]></Director>
  <Actor><![CDATA[]]></Actor>
  </Film>
<FilmData>

我的代码如下：
大概的思路是先将文件按全部读入到pbuf中，然后掉用sal_get_buf（）sal_get_txt（）函数来读取
<Film>
  <Title><![CDATA金庸]]></Title>
  <Director><![CDATA[]]></Director>
  <Actor><![CDATA[]]></Actor>
  </Film>
这里面的各项数据，现在问题是我的for循环来时在重复的读取第一个<file></file>之间的数据，我已经记录了每一次读取数据的指针然后再读，还是没找到错误在那。。。。
