Some patterns used in "replace text" block the whole IDE

Question

I sometimes need to do something like replace (.*) with tbl.\1 = rec.\1
This I thought should be achievable using regular expressions, but it is dangerous to use within sqldeveloper as it can freeze the whole program. Doing a single substitution works as expected, but doing a prompted replace shows that instead of performing the above once per line as expected, it is done recursively in seemingly never-ending loop, which I guess is what makes the IDE seem to freeze if one attempts a global replace.
Also I noticed that under 3.0 I can also replace .* with tbl.& = rec.& with the same (deceiving) result, but this seems unsupported under 3.1EA (albeit a fairly standard construct as RE's go).

OK STOP FOR A MOMENT ... i found a way to display the external text in a dynamic textbox
and i managed to let it display only one parte of the text...
my question now is:
var xmlData:XML = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = function(ok:Boolean){
    if(ok){
        trace(this);
        box1.text = this.firstChild.firstChild.firstChild.firstChild.nodeValue; /*using the xml file that i postet above i get the HEADLINE text of HOME and everything is ok*/
        box2.text = this.firstChild.firstChild.firstChild.secondChild.nodeValue;/*i wanted the second tag under HEADLINE to be displayed (body) but the command seconChild does not exist.. how do i tell him that i wantthe text of the HOME and not of HEADLINE???*/
    }else{
        trace("ERRORE CARICAMENTO XML");
xmlData.load("txtsito.xml");
i wanted the second tag under HEADLINE to be displayed (body) but the command seconChild does not exist.. how do i tell him that i wantthe text of the HOME and not of HEADLINE???
