Comment 2 for bug 517074

you could use xml2po, a tool that extracts translatable content into po files.

Have you considered using doctemplate to structure the project and support localization (text and images)?

It creates localized outputs of these types:
html (two versions)
docbook
pdf
epub

With a single command.

Install doctemplate from this ppa:
https://edge.launchpad.net/~doctemplate-team/+archive/ppa

Create a project with "doctemplate_setup_article"

Assumes docbook source format.
