原标题:xml filtering with python

我有下列文件:

<node0>
    <node1>
      <node2 a1="x1"> ... </node2>
      <node2 a1="x2"> ... </node2>
      <node2 a1="x1"> ... </node2>
    </node1>
</node0>

在<代码>a1=“x2”时,我想过滤<代码>node2。 用户提供需要测试和过滤的Xpath和属性价值。 我审视了一些像美丽的假象解决办法,但这种解决办法过于复杂,并有意保留案文。 我想将该文件与以前一样,有些内容被过滤。

您能否提出简单明了的解决办法? 这不应过于复杂。 实际的xml文件不像上文那样简单,但想法相同。
