提取标签 之间的数据

我有如下数据 如何打印两个标签之间的数据 我希望数据是命令分隔的 csv 格式

我的方法是将数据转换为水平格式，然后在每第四列后进行剪切并转换为垂直格式

xml文件中的数据

<?xml version="1.0" encoding="UTF-8" standalone="true"?>
-
<sst uniqueCount="12" count="12"
    xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
-
    <si>
        <t>"NAME"</t>
    </si>
-
    <si>
        <t>"Vikas"</t>
    </si>
-
    <si>
        <t>"Vijay"</t>
    </si>
-
    <si>
        <t>"Vilas"</t>
    </si>
-
    <si>
        <t>"AGE"</t>
    </si>
-
    <si>
        <t>"24"</t>
    </si>
-
    <si>
        <t>"34"</t>
    </si>
-
    <si>
        <t>"35"</t>
    </si>
-
    <si>
        <t>"COURSE"</t>
    </si>
-
    <si>
        <t>"MCA"</t>
    </si>
-
    <si>
        <t>"MMS"</t>
    </si>
-
    <si>
        <t>"MBA"</t>
    </si>
</sst>
      

我已经尝试过下面的命令不起作用..

awk '/<t/{flag=1;next}/<t/{flag=0}flag' abc.xml

即使尝试了下面的命令，它也给出了数据，但在单行中

awk -F'(</*t>|</*t>)' 'NF>1{for(i=2;i<NF; i=i+2) printf("%s%s", $i, (i+1==NF)?ORS:OFS)}' OFS=',' demo.xml

我想要以下数据作为输出

NAME,AGE,Course
Vikas,"25",MCA
Prabhash,"34",MBA
Arjun,"21",MMS

仅使用您显示的示例，您可以尝试以下操作。

awk -v OFS="," '
!NF || /^-$/{ next }
/<t>"COURSE"<\/t>/{
  foundAge=foundName=""
  foundCourse=1
  count=0
}
/<t>"AGE"<\/t>/{
  foundAge=1
  foundName=""
  count=0
}
/<t>"NAME"<\/t>/{
  foundName=1
  count=0
}
foundAge && match($0,/>[^<]*/){
  age[++count]=substr($0,RSTART+1,RLENGTH-1)
}
foundName && match($0,/>[^<]*/){
  name[++count]=substr($0,RSTART+1,RLENGTH-1)
}
foundCourse && match($0,/>[^<]*/){
  course[++count]=substr($0,RSTART+1,RLENGTH-1)
}
END{
  for(k=1;k<=count;k++){
    if(name[k]){
      print name[k],age[k],course[k]
    }
  }
}
'  Input_file

解释：对上述内容添加详细解释。

EDIT:根据OP的评论，如果一行中需要所有值，请尝试以下操作：

awk -v OFS="," '
!NF || /^-$/{ next }
/<t>"COURSE"<\/t>/{
  foundAge=foundName=""
  foundCourse=1
  count=0
}
/<t>"AGE"<\/t>/{
  foundAge=1
  foundName=""
  count=0
}
/<t>"NAME"<\/t>/{
  foundName=1
  count=0
}
foundAge && match($0,/>[^<]*/){
  age[++count]=substr($0,RSTART+1,RLENGTH-1)
}
foundName && match($0,/>[^<]*/){
  name[++count]=substr($0,RSTART+1,RLENGTH-1)
}
foundCourse && match($0,/>[^<]*/){
  course[++count]=substr($0,RSTART+1,RLENGTH-1)
}
END{
  for(k=1;k<=count;k++){
     if(name[k]){
     nameVal=(nameVal?nameVal OFS:"")name[k]
     ageVal=(ageVal?ageVal OFS:"")age[k]
     courseVal=(courseVal?courseVal OFS:"")course[k]
     }
  }
  print nameVal,ageVal,courseVal
