Hi I am not really sure if i am doing this right with XPath expression. I am trying to locate a text on DOM and this text is assingned to a variable. I have text stored in SQLite and i have retrievd the text and i am trying to locate it on the webpage which actually contains the text. so i ahve the following code:

var searchText = dataset[x]['selectedText'];
    	alert(dataset[x]['selectedText']);
    	var res = googbar_frames[0].contentDocument.evaluate("//*[.=searchText]",googbar_frames[0].contentDocument.body,null,XPathResult.ANY_TYPE,null);
    	alert(res.snapshotLength);

And i get the following error.

Error: Permission denied for <http://en.wikipedia.org> to call method XPathException.toString on <>.
Error: Permission denied for <http://en.wikipedia.org> to call method XPathException.toString on <>.

Have got the expression correct. I am trying to look for the text on DOM. Or am i going wrong somwehere? cheers
