删除字典列表字典中的项目

Question

这是我的示例输入文件：

{
"name": "756",
"children": [{
    "name": "Process Activities",
    "children": [{
        "name": "LOAD LIBRARY::shell32.dll"
    }, {
        "name": "#REDCREATE PROCESS::DLL INJECTION INTO PROCESS WITH ID 680 App=[C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp /SL5=$1D0314,1364673,56832,C://Blues//file.s62451 ]"
    }, {
        "name": "#REDLOAD LIBRARY::comctl32.dll"
    }, {
        "name": "LOAD LIBRARY::C://Windows//system32//uxtheme.dll"
    }, {
        "name": "LOAD LIBRARY::dwmapi.dll"
    }, {
        "name": "LOAD LIBRARY::UxTheme.dll"
    }, {
        "name": "#REDPROCESS CREATE::C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp /SL5=$1D0314,1364673,56832,C://Blues//file.s62451"
    }]
}, {
    "name": "File Activities",
    "children": [{
        "name": "FILE READ::C://Blues//file.s62451"
    }, {
        "name": "FILE OPEN::<R>C://Blues//file.s62451"
    }, {
        "name": "FILE OPEN::<W>C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp"
    }, {
        "name": "#REDEXECUTABLE FILE WRITE::C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp"
    }, {
        "name": "FILE CLOSE::C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp"
    }, {
        "name": "FILE CLOSE::C://Blues//file.s62451"
    }, {
        "name": "FILE OPEN::<R>C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp"
    }]
}, {
    "name": "680",
    "children": [{
        "name": "Process Activities",
        "children": [{
            "name": "#REDCURRENT PROCESS::C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp"
        }, {
            "name": "LOAD LIBRARY::C://Windows//system32//uxtheme.dll"
        }, {
            "name": "LOAD LIBRARY::dwmapi.dll"
        }, {
            "name": "LOAD LIBRARY::ADVAPI32.dll"
        }]
    }, {
        "name": "File Activities",
        "children": [{
            "name": "FILE OPEN::<R>C://Windows//Fonts//staticcache.dat"
        }, {
            "name": "FILE READ::C://Windows//Fonts//staticcache.dat"
        }]
    }]
}]
}

如果我有一个名为“处理活动”，“文件活动”，“注册表活动”或“网络活动”的子项，我必须删除该子项。所以这个过程就像树一样。

这是上面示例的输出：

{
"name": "756",
"children": [{
    "name": "680",
    "children": []
}

我尝试了以下内容： 这是我的代码：

import json
def infosorting(sample_dict):
   if sample_dict["name"] not in ['Process Activities', 'File Activities', 'Registry Activities', 'Network Activities']:
    for child in sample_dict["children"]:
          if child["name"] in ['Process Activities', 'File Activities', 'Registry Activities', 'Network Activities']:

       #sample_dict["children"].pop(sample_dict["children"].index(child))
                sample_dict["children"].remove(child)
                #del child

          else:
                infosorting(child)
  else:
    sample_dict ={}
  return sample_dict
def main():
  file_sample = open("/home/manchala/PdfJson/md5/file11.txt")
  fs = file_sample.read()
  sample_dict = json.loads(fs)
  new_dict=infosorting(sample_dict)
  print new_dict
if __name__=='__main__':
  main()

但我得到这样的输出

{
u 'name': u '756', u 'children': [{
    u 'name': u 'File Activities',
    u 'children': [{
        u 'name': u 'FILE READ::C://Blues//file.s62451'
    }, {
        u 'name': u 'FILE OPEN::<R>C://Blues//file.s62451'
    }, {
        u 'name': u 'FILE OPEN::<W>C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp'
    }, {
        u 'name': u '#REDEXECUTABLE FILE WRITE::C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp'
    }, {
        u 'name': u 'FILE CLOSE::C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp'
    }, {
        u 'name': u 'FILE CLOSE::C://Blues//file.s62451'
    }, {
        u 'name': u 'FILE OPEN::<R>C://Users//blues//AppData//Local//Temp//is-Q43LA.tmp//file.tmp'
    }]
}, {
    u 'name': u '680',
    u 'children': [{
        u 'name': u 'File Activities',
        u 'children': [{
            u 'name': u 'FILE OPEN::<R>C://Windows//Fonts//staticcache.dat'
        }, {
            u 'name': u 'FILE READ::C://Windows//Fonts//staticcache.dat'
        }]
    }]
}]

}

为什么我无法删除名为“文件活动”的孩子？ 请帮我弄清楚我的代码中有什么问题并帮我纠正。
