# Convert a scribus file to recoll HTML. This only handles the newer .sla
# files until I can have a look at an older .scd.
#
# We just hack into the scribus XML, taking advantage that the tag of
# interest is apparently always output on a single line.
# The text seems to be found in attribute CH of tag ITEXT, it is utf-8
#
# Tried to convert this to xsltproc but it seems that quite a few
# Scribus document are not actually proper xml

# A small sed program to join lines where they are broken inside an
# attribute value. The idea is that all scribus tag are apparently on one
# line except when there are embedded new lines in an attribute lie
# 'comments'. The first version of the sed script joins line which does not
# end with > with the next. It doesn't guard against an embedded '>'. The
# seconf joins line not beginning with '<' with the previous. It is much
# slower for some reason.
