Thank you! That gave me exactly what I was looking for.
Re-reading what I wrote I realized that I wasn't specific in the whole process I use. Notepad++ drops the results of the search into a separate window that I can then copy so I
only have the lines with the links I'm looking for, and not all the miscellaneous coding that's in the file. I paste those results into an OpenOffice document where I run the slightly modified search string using Find All and it highlights the results. With everything still highlighted I can then copy and paste just that data into another OpenOffice document. And, voila, I have the list of links that I was looking for. It would be awesome if OpenOffice had a Select Inverse like I use in Photoshop but this gets the job done.
