[total novice again ;-)]

Hi,

Ok, I've figured some of this pattern-matching out (yes, I'm really a
total novice at programming). Consider the following:

====================================
@data.gsub!(/<(text:span
text:style-name="T10")>(.*?)<\/text:span>/mois) do
'{' + '\bf ' + $2 + '}'
end
@data.gsub!(/<(text:span
text:style-name="Style2")>(.*?)<\/text:span>/mois) do
'{' + '\it ' + $2 + '}'
end
@data.gsub!(/<text:span.*?text:style-name=([\'\"])(.*?)\1>(.*?)<\/text:span>/)
do
tag, text = $2, $3
if inline[tag] then
(inline[tag][0]||'') + clean_display(text) +
(inline[tag][1]||'')
else
clean_display(text)
end
end
====================================

How can I condense this? I want something that says, eg.

If style-name equals "T10" or "Style2" or "Style3" then do \bf or \it
or \sl respectively. Otherwise, do clean_display (defined elsewhere).
The first line should look like this

==================
@data.gsub!(/<(text:span
text:style-name=("T10"|"Style2"|"Style3"))>(.*?)<\/text:span>/mois) do
==================

but how do I modify the

==================
'{' + '\bf ' + $2 + '}'
==================

line?

Best

You could perhaps have a hash:

replacements = { '"T10"' => "bf", '"Style2"' => "it", '"Style3"' => "sl" }

and then replace from the hash:

"{\\#{replacements[$1]}#{$2}}"

or something like that.

Hi Paul,

There are quite a few regular posters here who are pretty good with regular
expressions. I am sure we can offer some useful hints if we can see the
data plus the desired outcomes.

Ok, I was trying to avoid typing too much but I will post more
detail tomorrow morning. I am new to ruby, this list, and serious
programming so please bear with me as I get the hang of
appropriate/informative communication on this list.

Thank you, Paul!
