The following PowerShell script reads an input file, and
then outputs the strings/sentences/paragraphs that are in-between quotes. This
script works even if the quotations marks are on other lines. Added extras are
removing additional spaces and tabs so the output sentences don’t have ugly gaps
in them.
It was developed for getting ‘Descriptions’ out of mib
files.
Note: The script
has been formatted for blogger by removing leading tabs.
