Q: Need to select em in Selenium I am using Selenium IDE in Chrome. 
I have trouble as it's Ext JS, so certain class names are generated. I also might be having trouble due to the class name "x-list-body"?
I want to click on "This person here yes", like this:
Click: //div[@class='x-list']//em[.='This person here yes']

Here is the HTML from the webpage, excuse the mess:
<div class="x-list-body">
<div id="ext-gen159" class="x-list-body-inner">
<dl>
<dt style="width:100%;text-align:left;">
<em unselectable="on" "="">Woot Moot Boot</em>
</dt>
<div class="x-clear">
</div>
</dl>
<dl>
<dt style="width:100%;text-align:left;">
<em unselectable="on" "="">This is sparta</em>
</dt>
<div class="x-clear"></div></dl>
<dl>
<dt style="width:100%;text-align:left;">
<em unselectable="on" "="">Henry Print</em>
</dt>
<div class="x-clear"></div>
</dl>
<dl>
<dt style="width:100%;text-align:left;">
<em unselectable="on" "="">Minsy Blowman</em>
</dt>
<div class="x-clear"></div>
</dl>
<dl class="">
<dt style="width:100%;text-align:left;">
<em unselectable="on" "="">This person here yes</em>
</dt>
<div class="x-clear"></div>
</dl>
<dl class="">
<dt style="width:100%;text-align:left;">
<em unselectable="on" "="">Another cool person</em>
</dt>
<div class="x-clear"></div>
</dl>
</div>
</div>

Please do not give me JavaScript code etc..., I am using the FireFox addon IDE.
Thank you!

A: driver.findElement(By.xpath("//em[contains(text(),'This person here yes')]")).click();


A: Yes, class name is a problem. If you don't want an exact match, then change selector to match partial class name:
//div[contains(@class,'x-list')]//em[.='This person here yes']

Also since you are selecting a very particular text, you may not even need that div selector, unless another em on the page has exactly the same text. I.e. you may be able to use:
//em[.='This person here yes']
