Removes all lines between the lines containing "" and "", including these lines itself Backdrop: Sometimes when working with XML files without an graphical editor, large comment-/annotation-blocks taper the readability to walk through the file. I like to create a copy of such documents without these annotations. As the documentation itself is in documentation tags inside the annotation tags an therefore graphical editors tend to put the annotation tags in their own lines, this command removes all documentations within annotation-tags. Show Sample Output
-1awk "/<xsd:annotation>/{h=1};!h;/<\/xsd:annotation>/{h=0}" annotatedSchema.xsd -
