      Just a quick thought, don't you have to use the escape character \ for

  <DIV></DIV>&gt;I am 99% complete on a date format parser.=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;(will post when this question is answerd!)=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;The last item is how to parse out a substring bracketed =
by=20
  single quotes.=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;i.e.:=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;I have this var...=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt; var format =3D "EEEE, MMMM dd, yyyy ''G'' 'at' =
hh:mm:ss a z" ;=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;I can walk down this string and pull out "tokens" (same =

  character of 1 or=20
  <DIV></DIV>&gt;more in length: ex: EEEE, hh, z )=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;I do it like this...=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt; while ( i &lt; intFormatLen )=20
  <DIV></DIV>&gt; {=20
  <DIV></DIV>&gt; var token =3D "";=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt; curChar =3D strFormat.charAt(i);=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt; while (( strFormat.charAt(i) =3D=3D curChar ) =
&amp;&amp; ( i &lt;=20
  intFormatLen ))=20
  <DIV></DIV>&gt; token +=3D strFormat.charAt(i++);=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt; result +=3D formatOptions ( token );=20
  <DIV></DIV>&gt; }=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;Now, a double single quote (2 in a row) needs to be =
grapped and=20
  passed on=20
  <DIV></DIV>&gt;as a single token. but not 3 in a row, the third should =
be part=20
  of the=20
  <DIV></DIV>&gt;next token. It needs to grab 2 adjacent at a time.=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;If it finds one single quote, it needs to grab all =
characters=20
  until it=20
  <DIV></DIV>&gt;sees and other single quote. Yes, it needs to be able =
to handle=20
  an=20
  <DIV></DIV>&gt;embedded pair of single quotes.=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;So, if I have this...=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt; EEEE 'is walter''s birthday'=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;This should give me 3 tokens=20
  <DIV></DIV>&gt; 1) EEEE=20
  <DIV></DIV>&gt; 2) a SPACE=20
  <DIV></DIV>&gt; 3) is walter's birthday=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;I can grab all but #3! :(=20
  <DIV></DIV>&gt;=20
  <DIV></DIV>&gt;I have been banging my head for 3 days on this one, I =
just=20
  can't see it.=20
