Standard recommendation not to use regular expressions for working with HTML and/or XML.
Go for XPath Assertion instead, using it you can implement your requirement using XPath query like:
//yourElement[@yourTag!='null' and not(contains(@yourTag,' '))]
XPath language is quite easy, at least it is much easier to create and read XPath expressions rather than "regular" ones. Check out XPath Tutorial to get started and How to Use JMeter Assertions in Three Easy Steps guide to learn more about assertions available in JMeter.
