[Swftools-common] Text search in SWF

I trying to build a simple application in flex in which I render a swf in the application. I want to enable user to search text using a textbox (id="SearchInpt") and button (id="SearchBtn").

I used this following command to convert the pdf to swf
 pdf2swf -f file.pdf -o file.swf   (thanks Matthias)

I am able to load the swf file into the application, but search always fails. Below is the code I am using (source: http://wiki.swftools.org/index.php/How_do_I_highlight_text_in_the_SWF%3F).

Am I missing something in the code. I will be grateful for any help or pointers to resources.


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" >
            import mx.controls.SWFLoader;
            import mx.controls.Label;
            import flash.text.TextSnapshot;
           public var snapText:TextSnapshot;
            private function doSearch() : void 
                snapText = img.textSnapshot;
                if (SearchInpt.text != '' && SearchInpt.text.length > 1) {
                        var textPos:int = snapText.findText(0, SearchInpt.text, false);
                        snapText.setSelected( 0, snapText.charCount, false );
                if (textPos > 0) {
                    do {
                        snapText.setSelectColor( 0xFFEF00 );
                        snapText.setSelected( textPos, textPos + SearchInpt.text.length, true );
                         textPos = snapText.findText(textPos + SearchInpt.text.length, SearchInpt.text, false);
                    while (textPos > 0)
                    Alert.show( "Not found.", "Information" );                
                    snapText.setSelected( 0, snapText.charCount, false );                   

        <mx:Panel title="SWF Player" y = "50" width="100%" height="100%">
             <mx:Canvas id="canvas" width="100%" height="100%">
                   <mx:TextInput x="10" y="21" width="80" id="SearchInpt"/>
                   <mx:Button x="98" y="21" label="Search" id="SearchBtn" click = "doSearch()"/>
                   <mx:SWFLoader id ="img" source="C:/file.swf" y="50" />
