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? -Jayson > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:flashcoders- > [EMAIL PROTECTED] On Behalf Of elibol > Sent: Tuesday, January 17, 2006 2:25 PM > To: Flashcoders mailing list > Subject: Re: [Flashcoders] efficient htmltext.reduce() function? > orsimilaridea? > > I hate to impose, but my curiousity is forcing me to question: what is the > reason for html reduction?
