Question

NSString *htmlDataString = [newView stringByEvaluatingJavaScriptFromString: @"document.documentElement.getElementsByClassName('field-item even')[0]"];

The webview called newView is being setup correctly as it works for other bits of javascript so it must be in my syntax.

The div class looks like so:

<div class="field-item even" property="content:encoded">

After break pointing htmldatastring and stepping into it, it just has the values: @""

Answer 1

You are selecting element by id, but you gave it as a class in your markup. You should do:

<div class="field-item even" property="content:encoded">

Then refer in objc as:

NSString *htmlDataString = [newView stringByEvaluatingJavaScriptFromString: @"document.documentElement.getElementById('someId')[0]"];
