Tree View: Expanding a node by searching for element by text using xpath

Hello,

I am quite new to Selenium so please be gentle

I have a telerik radtreeview, and I am trying to expand a node by searching for the text. I can select the text for the node using the following:

driver1.findElement(By.xpath("//*[contains(text(), '" + a_location1 + "')]")).click();

Where a_location1 is a variable which contains the name of the node I want "Demo Store".

I am also able to expand the first node in the tree using the following:

driver1.findElement(By.xpath("//span[@class='rtPlus']")).click();

But what I want is to expand the node associated with a_location1. This is what the html looks like. The rtPlus is the expand control, the rtIn is the associated text.

Code:

<DIV class="rtMid">
<SPAN class="rtSp"></SPAN><SPAN class="rtPlus"></SPAN><IMG class="rtImg" alt="" src="source.png" /><SPAN class="rtIn">Demo Store</SPAN>
</DIV>


Any help would be appreciated!

Think I managed to figure it out with:
driver1.findElement(By.xpath("//span[text()='"+ a_location1 +"']/preceding-sibling::span[@class='rtPlus']")).click();
