That is a html response. You will need to add an extractor to parse the HTML and extract the data. Using Jmeter right click on the thread group and select post processors, then CSS selector extractor. Once added define the variable name as var1, set the CSS selector expression to iframe, set the attribute to sessionKey, set match number to 1 and tick box for empty variable if nothing is found, like this:

Bare in mind that Jmeter offers a wide variaty of extractors (xpath, json, regular expression and so on), you can also use xpath or regexp here if that is what you prefer.
