<p class="MsoNormal"><span style="font-size:8.0pt;font-family:"Courier New""> set("HOST" value("location")<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But without changing the actual log message. The goal is to create a variable from a regular expression of the host field in the message that I can then use in a destination path.<o:p></o:p></p>
