I have the following elements

```
<li data-attr="sessionContext='test session'"></li>
<li data-attr="sessionContext='test session 12345'"></li>

// I want to get all elements with [data-attr=someContext*=] -doesn't 
matter someContext= value, but doesn't work
$("[data-attr]") // gets all elements, but not sessionContext only
$("[data-attr='sessionContext=test session']") // works but for single element only

```
