can you spot the error in this xpath

I'm a little new to xpath and I was wondering if you anyone can help me understand what's wrong with the following xpath query. The server is telling me I have an "invalid predicate"

Here's the xpath:

xpath("div[span[@class='paragraphnumber]/text()='$next_pn']/@id")

I want this to find the @id of the div which contains within it a span element with the @class of "paragraphnumber" and the text which equals the number contained in the variable $next_pn. The div would look something like this:

<div id="pl8ddjkdj"><span class="paragraphnumber">3</span>lor ipsum etc etc</div>

Basically, I'm starting with the number I want to be able to find the unique id of this div.

Thanks for your help.

You have just missed a single quote (') after the name of the class paragraphnumber.

This:

xpath("div[span[@class='paragraphnumber]/text()='$next_pn']/@id")

should be

//                                     v
xpath("div[span[@class='paragraphnumber']/text()='$next_pn']/@id")
