how to select combobox item internet explorer for extjs application?

First of all the code below works for my app for non ie browsers (i am using perl with selenium for extjs testing):

http://seleniumexamples.com/blog/examples/select-an-option-from-an-extjs-combobox/

unfortunately t开发者_开发知识库he xpath library gives zero xpath count if i dare to add the visibility condition. The page content changes, so first i have one list of combobox items (this i can click) then later there are two lists. When I address the 2nd list the first list item gets clicked (they have same content and no distinguishing id). Using last() did not help.

I tried a zillion different xpaths but could not select an item from a 2nd combobox in extjs. selenium does return the correct html source but i can not get to the 2nd combobox. If I first open the 2nd combo then I can not select items in the first one.

At a certain point I had hope that this would work:

    if($comboindex==1)
    { 
        $locator="//div[contains(\@class, 'x-combo-list')]/descendant::div[contains(\@class, 'x-combo-list-item')][text()='".$combovalue."']";
    }
    else
    {
        $locator="//div[contains(\@class, 'x-combo-list')]/following::div[contains(\@class, 'x-combo-list-item')][text()='".$combovalue."']"; 
    }

but it did not...

You could try using css selectors instead of xpath, this guide might have what you need. http://saucelabs.com/blog/index.php/2010/01/selenium-totw-css-selectors-in-selenium-demystified/
