How do I remove everything outside of marked lines?

[Aimee Elizabeth]

Hello,

I have marked all <title> and all content:encoded and now I want to remove everything that doesn’t fall between those tags.

Thanks in advance for any assistance.

Hello Aimee-Elizabeth,

in order to get lines removed by using bookmarks you either have to
mark every line which should be removed or mark lines which shouldn’t be removed
and then call the appropriate menu entry like

Search->Bookmark->Remove unmarked lines

but you cannot specify a block of lines surrounded by bookmarks to get treaten as bookmarked lines.

Cheers
