我使用 libxml2.so 在 LINUX 平台上解析 C 中的 XML 文件。 我用下面提到的格式有我的 XML 格式。 我可以在文件中存有多个账户 。 在有人在论坛向我提出建议后, 我第一次使用 libxml 。 我只能用一个账户来解析文件 。 如果有多个账户, 我不懂如何执行。 任何人都在 C, Libxml 在 Linux 上执行过这样的操作 。

<ACCOUNT>
  <ACCOUNT_NO> 123 </ACCOUNT_NO>
  <NAME> XYZ </XYZ>
  <STATE> GA </STATE>
</ACCOUNT>

<ACCOUNT>
  <ACCOUNT_NO> 223 </ACCOUNT_NO>
  <NAME> ABC </XYZ>
  <STATE> FL </STATE>
</ACCOUNT>

每个 XML- 定义, 如果您有更多的 & lt; ACCOOUNT>, 您需要一个周围标签 f. e. & lt; ACCOOUNTS> 围绕所有 & lt; ACCOOUNT> 标签 。

如果您有的话, 您可以进入孩子的“ 进入”, 您可以在 - & gt; 下一步的节点上, 时间( ) 。

EDITH: 我猜您使用 DOM 模型。 但如果您有许多(!) & lt; ACCOOUNT> s, 您应该为记忆原因将 SAX 连接到 SAX 。 DOM 构建一个完整的( M), 将 (D) 对象应用到 (O) 内存中 。

在SAX, 你为每个启动标签和结束标签及数据 建立一个州立机器, 它在读取文件/ 记忆完成时启动 。

EDITH 2: 如果您需要找到一个特殊值, 您应该考虑将键值( count_ no? ) 放到一个属性中, 如 < ACCOUNT No= "123" & gt; & lt; NAME> & lt; XYgt; & lt; STate> FL< /STATE> /STATE> /ACCOUNT>
