Why not just strip out tags ya don't need? Using regex strip out
all "<font*>" and "</font>" and/or the "<b></b>" and "<i></i>"
stuff.. When I first started reading this thread I was thinking along
the lines of real optomizing.. Say ya got:
"<font face='verdana'><b><i>some <font face='verdana'><b>text</b></font>
</i></b></font>"
which should be optomized to:
"<font face='verdana'><b><i>some text</i></b></font>"
This could be a chore, but just ripping out tags.. that would be easy..
Something you could do is look into XMLToObject.. Run that on the
html string and then pull out all the data it spits out.. If ya look into a
"traceObject" you can get an idea on how to traverse what xmlToObject
spits out.
For an example, your "<font face='verdana'><b>hello world</b></font>
<br><i>abc123<br>hi again world<br></i>" after ran through xmlToObject
spits out this...
br: [object Object]
i: [object Object]
br: [object Object]
br: [object Object]
data: undefined
attributes: undefined
data: hi again world <--
attributes: undefined
data: abc123 <--
attributes: undefined
data: null
attributes: undefined
font: [object Object]
b: [object Object]
data: hello world <--
attributes: undefined
data: null
attributes: undefined
face: verdana
You could traverse this object to get what ya want..
Using just the data's and br's you'd get:
"hello world<br>abc123<br>hi again world<br>"
We could call this your 10% call... But let's not..
Let's call this "level 1", or max reduction cuz I'd assume
you'd at least want the <br>'s but you could replace
<br>'s with spaces and call that the max reduction or
"level 1".. Now we can build a "level 2" model.. if it's
in a "b" or "i" object, wrap the text with the appropreate
tags.. "level 3" could be to allow levels 1 and 2, and
font tags.. ect.. Also, with this method you could strip
attributes.. like allowing font color changes, but not
the font family..
This is prolly how I'd go about doing what your asking..
All I used was "xmlToObject" and "traceObject" to get
to this point.. You could also rework the xmlToObject
to spit out what you want.. Hope this helps :)

orsimilaridea?
Say I have this htmltext
"<font face='verdana'><b>hello world</b></font><br><i>abc123<br>hi again
world<br></i>"
And it is being appended with other html lines over time, but no two
lines are the same, nor is there a pattern of <br>'s being a common
separator per 'line'.
I want to be able to execute something like
myHtmlText=myHtmlText.reduce(10);
And have it become something like:
"<i>abc123<br>hi again world<br></i>"
Seeing as that's the lowest amount closest to 10% reduction it could be
trimmed to without breaking the html output when displayed...
If it was:
"hi again world<br></i>"
It wouldn't work as needed.. and would paralyze an htmltext box from
showing anymore text from that point forward.
Even if just a 50% reduction could be worked out easily.. that'd at
least be functional..
Do you see now the dilemma?

I hate to impose, but my curiousity is forcing me to question: what is
the
reason for html reduction? How does a regular html tag look compared
to a
reduced one? What exactly does the algorithm do?
I apologize for side tracking, I hope you find the answer you're
looking
for
Jayson.
