I have a boatload of text files (see below) that I need to parse. They contain chapter information that I’d like to capture and use to create associated records. Report has_many :chapters

Basically I need to read each line and for each BookmarkTitle capture the chapter name (ignoring the CR 
) and then capture the BookmarkPageNumber. Then bundle the pairing up and create a new record with it: report.page.create(title: bookmark_title, page_number: bookmark_page_number)

I’ve played a bit with IO‘s readline but not sure how to capture the contents… a RegEx perhaps? or a more Rails-y way?

sample txt file:

InfoKey: Creator
InfoValue: Adobe Acrobat 9.3.4
InfoKey: Producer
InfoValue: Adobe Acrobat 9.34 Paper Capture Plug-in
InfoKey: ModDate
InfoValue: D:20110315193536-04'00'
InfoKey: CreationDate

    /^BookmarkTitle:\s*(.+?)
\s*BookmarkLevel:\s*(\d+)\s*BookmarkPageNumber:\s*(\d+)\s*$/m

    I’m sorry, I’m not a Ruby-On-Rails Developer, but that regular expression will match each bookmark, and return:

    • The entire record
    • The Title (as a sub-match)
    • The Level (as a sub-match)
    • The Page number (as a sub-match)

    It does assume that level and page number are numeric without spaces, comma or decimals. But that could easily by changed.
