用java解析平面文件

Question

I want to parse below wmi output to hashmap as a key value pair using java.Please give me suggestions .. My WMI Output contains 2 rows with multiple columns, first row is header and second row contains data. I want either regex or any approach to seperate the header with corresponding data as a key value for hashmap.

I am not getting any idea how to proceed...

Caption                  Description              IdentifyingNumber  Name                   

Computer System Product  Computer System Product                     HP xw4600 Workstation                   

Parsing output should be like ...

Key = Value

Caption = Computer System Product

Description = Computer System Product

IdentifyingNumber =

Name = HP xw4600 Workstation

Answer 1

If your file format is always the same, you can easy use parser:

FileInputStream fis = new FileInputStream(filename);
InputStreamReader isr = new InputStreamReader(fis);
Reader in = new BufferedReader(isr);
String[] array = new String[2];
for(int i = 0; i < 2; i++)
{
    ((BufferedReader)in).readLine();
}
for(int i = 0; i < array.length; i++)
{
   array[i] = ((BufferedReader)in).readLine();
   if(array[i] == null)
   {
    array[i] = ""; //$NON-NLS-1$
   }
}
in.close();
String[] headers = array[0].split(Pattern.quote("\t")); //$NON-NLS-1$
String[] values = array[1].split(Pattern.quote("\t")); //$NON-NLS-1$

And then running through both and filling hashmap

我将 wmi 输出格式化为列表，现在很容易格式化输出。
