Lilypond lyrics extraction

[Dominic Neumann]

Hi,

I´m currently developing a system for the management of songbooks. It
allows me to compose different songbook collections which then are
created with lilypond-book and LaTeX.

Now I want the lyrics of the songs to be included in the database.
Then I could search for songtext snippets to find a special song.

Is there a way to do this directly with lilypond or should I write it myself?
