Top Forums UNIX for Dummies Questions & Answers Explanation of the command sed -n -e 's_.*>\(.*\)<.*_\1_p' filename.xml Post 302443826 by pludi on Tuesday 10th of August 2010 07:11:25 AM

Code:
sed -n -e 's_.*>\(.*\)<.*_\1_p' filename.xml

  • Brown: Go through the file, but don't print anything by default
  • Red: The following regex is a substitution
  • Blue:Look for any text on a line leading up to a right angle bracket, and ending with any text after a left angle bracket
  • Green: Capture and save the text between the brackets
  • Orange: Replace anything that matches the blue part with the saved capture
  • Dark Blue: If something is matched and substituted, print the substituted line

Basically, it extracts the text between tags in the XML file, without changing it.
