This works fine:
<a href=""_1a904m3mg.htm"" >Help Builder Features</a>  
 
This will select the first (non-matching) href and selects through the second - need to avoid this
<a href=""_2a904m3mg.htm"" >Help Builder Features</a> asdsad <a href=""_1a904m3mg.htm"" >Help Builder Features</a> 
 
Need to also match something like this:
<a href=""path/_1a904m3mg.htms"" >Help Builder Features</a>
