问题描述

这是后续问题的问题: Groovy解析文本文件

p>

现在的区别是我的文件有一个标题,我试图先读过标题,然后转到我想要的内容上,但出于某种原因,

  def dataList = [] 
def theInfoName ='testdata.txt'
布尔headersDone = false //标题默认为false

如果(!theInfoFile.exists()){
println文件theInfoFile = new File(theInfoName)

文件不存在
else {
def driveInfo = [:]
//遍历文件中的每一行
theInfoFile.eachLine {line - >

//这是我试图说明头部
if(!headersDone){//如果线条包含...,如果它将headerDone变为true
if(line.contains(...)){
headersDone = true
}
} else {
//如果该行不为空
if(line.trim()){
//分解为一个键值
def(key,value)= line.split('\ t:').collect {it .trim()}
//并将它们存储在driveInfo Map中
driveInfo。$ key= value
}
else {
//如果行是空白的,并且我们有一些信息
if(driveInfo){
//将它存储在列表中
dataList<<< driveInfo
//并清除它
driveInfo = [:]
}
}
}
//当我们完成文件时,存储任何其余数据
if(driveInfo){
dataList<< driveInfo
}
}

dataList.eachWithIndex {it,index - >
printlnDrive $ index
it.each {k,v - >
println\ t $ k = $ v
}
}

我试用了上一篇文章中提供的代码,以确保它不是我做的不同的事情,它的输出相同。



会发生什么,它发布相同的信息块11次。



标题看起来如下:

 随机日期信息以及其他信息
稍微更随机的信息后跟

有人知道为什么要打印出重复的信息吗?

解决方案

问题在于添加了last driveInfo dataList

  //当我们完成文件时,存储任何剩余的数据
if(driveInfo){
dataList<< driveInfo
}

它必须是一个大括号,否则它属于它到每条线关闭。

This is a follow up to the question asked here: Groovy parsing text file

The difference now is my file has a header, I attempted to read past the header first and then onto the content that I am wanting, but for some reason it doesn't seem to cooperate.

def dataList = []
def theInfoName = 'testdata.txt'
boolean headersDone = false    //header set to false by default

File theInfoFile = new File( theInfoName )

if( !theInfoFile.exists() ) {
  println "File does not exist"
} else {
  def driveInfo = [:]
  // Step through each line in the file
  theInfoFile.eachLine { line ->

  //this is where im trying to account for the header
  if(!headersDone) {      //look if line contains "..." if it does that turn headersDone to true
   if(line.contains("...")) {
     headersDone = true
   }
  } else {
     // If the line isn't blank
     if( line.trim() ) {
       // Split into a key and value
       def (key,value) = line.split( '\t: ' ).collect { it.trim() }
       // and store them in the driveInfo Map
       driveInfo."$key" = value
     }
     else {
       // If the line is blank, and we have some info
       if( driveInfo ) {
         // store it in the list
         dataList << driveInfo
         // and clear it
        driveInfo = [:]
       }
     }
  }
  // when we've finished the file, store any remaining data
  if( driveInfo ) {
    dataList << driveInfo
  }
}

dataList.eachWithIndex { it, index ->
  println "Drive $index"
  it.each { k, v ->
    println "\t$k = $v"
  }
}

I tried it out with the code provided in the previous post to make sure it wasn't something I was doing differently and it came with the same output.

What happens is that it posts the same block of information 11 times.

The header looks is the following:

Random date information here with some other info
Slightly more random information followed by

Examining hard disk information ...

HDD Device 0 : /dev/sda
HDD Model ID  : ST3160815A
HDD Serial No : 5RA020QY

Interface    : IDE/ATA
Temperature         : 33 C
Health  : 100%
Performance  : 70%
Power on Time : 27 days, 13 hours
Est. Lifetime : more than 1000 days

HDD Device 1 : /dev/sdb
HDD Model ID  : TOSHIBA MK1237GSX
HDD Serial No : 97LVF9MHS
HDD Revision  : DL130M
HDD Size     : 114473 MB
Interface    : S-ATA
Temperature  : 30 C
Health  : 100%
Performance  : 100%
Power on Time : 38 days, 11 hours
Est. Lifetime : more than 1000 days

Does anyone know why it is printing out duplicate of the information?

解决方案

The problem is the addition of the "last" driveInfo to the dataList:

// when we've finished the file, store any remaining data
if( driveInfo ) {
   dataList << driveInfo
}

It has to be one curly brace below its current position, otherwise it belongs to the eachLine closure.
