copied!<p><strong>I need to match following statements:</strong></p> <pre><code>Hi there John Hi there John Doe (jdo) </code></pre> <p><strong>Without matching these:</strong></p> <pre><code>Hi there John Doe is here Hi there John is here </code></pre> <p>So I figured that this regexp would work:</p> <pre><code>^Hi there (.*)(?! is here)$ </code></pre> <p>But it does not - and I am not sure why - I believe this may be caused by the capturing group (.*) so i thought that maybe making * operator lazy would solve the problem... but no.
