[webdriver]By.cssSelector question

[Nilesh]

I am trying to replace an xpath with css selector. For example for
below html code, I have something like,
By.xpath(".//div[contains(text(), '1 - 15 of 82')]")
I want to replace this with
By.cssSelector("div:contains('1 - 15 of 82')"). However this is not
working.

If I try By.cssSelector("div#tblCampaign_paginate>span>div")- it works
but I want to use 'contains' in the css selector somehow. What am I
doing wrong?

I am using 2.0a7, Windows XP and Java.

Thanks,
-Nilesh

<div class="dataTables_paginate" id="tblCampaign_paginate">
<span class="prevGridFirst " id="tblCampaign_first">&nbsp;</span>
<span class="prevGrid " id="tblCampaign_previous">&nbsp;</span>
<span>
<div style="padding-right: 6px;"> 1 - 15 of 82 </div>
</span>
<span class="nextGrid DisabledNav" id="tblCampaign_next">&nbsp;</
span>
<span class="nextGridLast DisabledNav" id="tblCampaign_last">&nbsp;</
span>
</div>

:contains was removed from the CSS3 spec [1], which is only a draft,
and wasn't present in the CSS2 spec.

We delegate to the underlying browsers' CSS selector implementation
(and happen to fake in the behaviour in IE, which doesn't support CSS
selectors), so cannot make any promises about supporting particular
selectors. You can be fairly sure that CSS2 is supported everywhere,
though.

Thanks Daniel. I didn't know that webdriver API fakes CSS selectors in
IE. I was wondering if replacing xpaths by CSS selectors would give me
any speed improvement in IE. Is that a recommended approach in
general?
