提取数据后在JSON行之间插入分隔符

标签： json parsing awk sed extract

我有一个需要分析的811行JSON文件。现在，我正在使用以下命令来解析我感兴趣的数据（{awk是必需的，因为我使用的JSON不能以适当的数组提供数据）： 

sed 's/},/},\n/g' 1st_run.json |awk '/"characater"/ { gsub("\"characater\"", "\"char" ++n "\"", $0) } 1'| jq -r '.frames.frame.lps.lp|.characters[]|[.code_ascii,.confidence]|@tsv'

这项工作正常，但我收到大量无法以任何方式分隔的数据。如何至少在JSON中每行有可分析结果的行后插入定界符？

输入

我的JSON输入类似：

答案 0 :(得分：0)

您可以使用awk为每行打印额外的换行[ ]和,。

awk 'BEGIN {print "["} END {print "]"} {gsub(/characater/, "char" ++n); print $0 ","}'

答案 1 :(得分：0)

好吧

我通过编写可以处理格式错误的JSON数据的Python脚本解决了这个问题。 这个想法是分别遍历每一行，然后用子字符串将内容分解，以提取ascii_code和confidence，最后它们看起来像：

#!/usr/bin/python

def mysplit( str ):
    spltstr = str.split("code_ascii")
    itr = iter(spltstr)
    next(itr)
    for k in itr:
        a = k.split("\"")
        print a[2] + "     " +a[6]

filepath = 'test2.json'
with open(filepath) as fp: 
    line = fp.readline()
    cnt = 1 
    while line:
        print "----------"
        mysplit(line)
        line = fp.readline()
        cnt += 1

我认为这应该为我做很多...
