Remove Wikipedia references from HTML
The Problem Being Solved
Text that was originally sourced from Wikipedia will have a large number of references that detract from the flow of the text when it is printed. This "perl one-liner" removes the Wikipedia references from an HTML file downloaded from FireFox while leaving other references intact. It was tested on a Macintosh but the perl code is general and should also work on Windows (either as is or in some minor modification that it would be helpful for someone to test/contribute)
The following code will remove all of the Wikipedia references
1. Use the "File/Save Page As..." to save the page to a file myfile.html. Note that FireFox will also create a separate folder with all of the ancillary files for the page—images and the like—which you just leave as-is.
2. In the Terminal, run
perl -npe 's/<a href=\"http:\/\/en\.wikipedia\.org\/wiki.+?>(.+?)<\/a>/$1/g' myfile.html > mynicefile.html
where myfile.html is the name of the file you just saved and mynicefile.html is the name of the new file.
3. Use "File/Open File" to open the new file, which you can then print.
These will take you to pdf files printed from FireFox showing the before and after versions of a file
