You should definetly be looking into regular expressions. The following
could be wrapped up in a utility class and help build your method:
var regex:RegExp = /<.*?>.*?<\/.*?>/g;
var str:String = myHtmlTextBox.text; // or wherever you get your source
text
var result:Object = regexp.exec(str);
while(result != null) {
trace(result.index + ", " + result);
// Place the result in a new string or array and do whatever
// processing you'd like
result = regex.exec(str);
}

Subject: [Flashcoders] efficient htmltext.reduce() function? or similar
idea?
Does anyone have any divine wisdom for safely and efficiently "reducing"
an htmltext string down in size?
I've been using old code for a while that simply loops looking for html
tags.. and if it's a known "paired" tag set (like font), looks for the
closing tag, and then, substring's from that point onward (thus removing
everything ahead of the last complete tag set), and effectively reducing
the overall size of the htmltext so that it doesn't forever build in
size, and in turn bring flash to its knees if the string gets too long.
The problem with this is its slow... and risky..
sometimes.. it fails to match a paired set.. and the output into the
flash textbox breaks -- that is -- no more appended text will be seen
from that point onward.. and the box appears "Dead" because of broken
tags.
Ideally for me at least.. a function could be called such as:
myHtmlTextBox=myHtmlTextBox.reduce(10);
whereby 10 is used such that the result has about 90% remaining (which
is obviously a challenge because of the variable lengths of tag
groupings among formatted html..)
Any ideas? This is a hard topic to google and search the archives with..
Thanks!
