I have several xml files. They're very big, and my computer is quite slow. I can't open them in notepad. What is the fastest, easiest way to divide these files into equal parts, still in xml format, in Windows?

  • Do the individual files have to be *valid* XML? – Harry Johnston Jan 16 '12 at 01:00
  • harry, They don't have to have headers, if that's what you mean. If I can just reduce the file sizes, I can open them and edit them to make them valid, manually, you know? I figure that's a maximum of 30 operations. So, no, they don't. – Wolfpack'08 Jan 16 '12 at 01:39

  1. Install MSYS for Windows

  2. You can then use the sed command to pipe chunks of your file into another temp file.

    sed -n [start],[end]p filename > tmp.xml

where, [start] is the starting line number, and, [end] is the ending line number. Of course, you'll have to run this command repeatedly. And, you'll need to know the total number of lines to divide the file into equal parts.

  • anirvan, I don't know how to get the number of lines the file contains. Could you tell me that as well? It doesn't really need equal parts. Is there an `EOF` option, so that when I start getting `line xxxxxxxx does not exist` errors, I can just use `EOF`? – Wolfpack'08 Jan 13 '12 at 12:11
