Full Discussion: Replacing HTML tags with sed
Top Forums UNIX for Dummies Questions & Answers Replacing HTML tags with sed Post 302852867 by Corona688 on Thursday 12th of September 2013 02:08:25 PM

sed uses regexes, not globs, which explains part of your difficulty.

Code:
files*

In shell globbing, * means "anything else". In regex, it means "zero or more of the previous". So files* would match files, filess, filesssssssssssssssss, but wouldn't match files\

The regex equivalent would be .*, where . is a special character mean "match anything". But I'd try something a little trickier, to match > so that part of the regex doesn't scan outside the tag it started in. [] let you specify a range to include or exclude. [A-Z] would match a single letter in A-Z range. [^A-Z] would match a single character not in the A-Z range. [^>] would match anything that's not an end-of-tag character.

So, [^>]* would match zero or more non-> characters, swallowing up the rest of the tag and stopping right before >.

This works on the HTML you posted:
Code:
sed 's#<a href="files\\[^>]*><img src="thumbnails\\[^>]*></a>#<img src=redact.png>#g'

html::formhandler::widget::form::simple

HTML::FormHandler::Widget::Form::Simple(3pm)		User Contributed Perl Documentation	      HTML::FormHandler::Widget::Form::Simple(3pm)

NAME

       HTML::FormHandler::Widget::Form::Simple - widget to render a form with divs

VERSION

       version 0.40013

SYNOPSIS

       Role to apply to form objects to allow rendering. This rendering role is applied to HTML::FormHandler by default. It supports block
       rendering. (HTML::FormHandler::Blocks, HTML::FormHandler::Widget::Block)

       Relevant flags:

	   do_form_wrapper - put a wrapper around the form

       If the wrapper_tag is a 'fieldset' (default if not specified) the wrapper goes inside the form tags (because it's not valid to put it
       outside of them). If the wrapper_tag is something else, it will go around the form tags. If you're doing one kind of wrapper and want
       another one, you can achieve that result by using the 'before'/'after' tags or the 'after_start'/'before_end' tags.

       Supported tags:

	   wrapper_tag -- tag for form wrapper; default 'fieldset'
	   before
	   after
	   after_start
	   before_end

	   messages_wrapper_class -- default 'form_messages'
	   error_class -- default 'error_message'
	   error_message -- message to issue when form contains errors
	   success_class -- default 'success_message'
	   success_message -- message to issue when form was submitted successfully
