R – text matching in actionsript

actionscript-3flex3

Hi I have some html text coming from an rich text control.
something like:

<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="Verdana" SIZE="10" COLOR="#0000FF"   LETTERSPACING="0" KERNING="0"><A HREF="event:http://bbc.co.uk" TARGET="_blank"><U>l</U></A><U>ink1</U><FONT COLOR="#000000"> blah blah blah. another <FONT COLOR="#0000FF"><A HREF="event:http://cnet.com" TARGET="_blank"><U>link2</U></A></FONT> blah blah</FONT></FONT></P></TEXTFORMAT>

I would like to extract all A tags ie:

<A HREF="event:http://cnet.com" TARGET="_blank"><U>link2</U></A>

Should I be looking into reg expressions or are there any string utils that would accomplish this.

Any hints/help much appreciated.

Yaa, You need to look into regular expressions because String utilities are basic String manipulation techniques. You can start with this:

var pattern:RegExp = /<A.*?</A>/;
var str:String = '<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="Verdana" SIZE="10" COLOR="#0000FF"   LETTERSPACING="0" KERNING="0"><A HREF="event:http://bbc.co.uk" TARGET="_blank"><U>l</U></A><U>ink1</U><FONT COLOR="#000000"> blah blah blah. another <FONT COLOR="#0000FF"><A HREF="event:http://cnet.com" TARGET="_blank"><U>link2</U></A></FONT> blah blah</FONT></FONT></P></TEXTFORMAT>';
trace(pattern.exec(str));

It will output <A HREF="event:http://bbc.co.uk" TARGET="_blank"><U>l</U></A>.

R – TextArea() – handling text content as list of words

Nope. Just get the text in there and use a String.Split.

Besides, if there were such a method, it would also do the split.

R – Loading ISO8851 text file to TextField()

Deleted old post from here, see history for details.

I found the answer for you. Good news: no need for PHP magic! Here's how to do it:

var ldr:URLLoader = new URLLoader();
ldr.dataFormat = URLLoaderDataFormat.BINARY;
ldr.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
ldr.addEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler);
ldr.addEventListener(Event.COMPLETE, function (event:Event):void {
    var bytes:ByteArray = ByteArray(ldr.data); 
    var text:String = bytes.readMultiByte(bytes.length, "iso-8859-1");
    ...
});
ldr.load(new URLRequest('http://server.dom/path/to/your-file'));

You need to substitute "iso-8859-1" with the appropriate encoding. You can find the list of valid encodings here.
