我希望能够访问XML文件的数据

<?xml version="1.0"?>
<MY>
  <Foo id="1" name="test">
    <Argument name="a" />
  </Foo>
  <Foo id="2" name="test2">
    <Argument name="a" />
    <Argument name="b" />
  </Foo>
  <Other id="2" name="someOther"/>
</MY>

我想例如用它的参数读出每个Foo,我怎么能用Haskell做到这一点？(我想使用HaXml模块)

我不知道从哪里开始.

我在系统上安装HaXml时遇到问题.

我已经安装了Haskell平台并使用了以下链接中提供的clang-wrapper补丁:http://www.haskell.org/platform/mac.html

当我尝试运行时,cabal install HaXml我得到以下错误.我已经通过做一些研究尝试了所有的东西,但仍然没有运气来解决这个问题.我甚至尝试单独安装此链接http://hackage.haskell.org/package/HaXml上的依赖项,然后尝试安装该程序包但仍然没有运气.我在终端中收到以下错误消息:
