Replace this:
  <SPAN id=google-navclient-hilite style="COLOR: black; BACKGROUND-COLOR: cyan">Word</SPAN>
with this:
  Word
Notes:
  The chars '<'>' obviously appear in the html code as &lt; and &gt;
  The minimal or lazy search operator used in Visual Studio is '#' which is roughly equivalent to '+?' in other RegEx syntax.
  {...} is the tagged expression to be replace - again, Visual Studio syntax.

Test vectors used (snipplr stripped the complete SPAN markup):
 <SPAN>file</SPAN> (expect file)
 <SPAN>file</SPAN> (expect file)
 <SPAN>file</SPAN> (expect file)
 <SPAN>aaa</SPAN> (expect aaa)
 <SPAN>file</SPAN><SPAN>file</SPAN> (expect filefile)
 <SPAN>file aaa</SPAN> (expect file aaa)
