<DIV></DIV>&gt;Date: Tue, 23 Jul 2002 20:18:30 -0500 (CDT) 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I am 99% complete on a date format parser. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;(will post when this question is answerd!) 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;The last item is how to parse out a substring bracketed by single quotes. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;i.e.: 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I have this var... 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; var format = "EEEE, MMMM dd, yyyy ''G'' 'at' hh:mm:ss a z" ; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I can walk down this string and pull out "tokens" (same character of 1 or 
<DIV></DIV>&gt;more in length: ex: EEEE, hh, z ) 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I do it like this... 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; while ( i &lt; intFormatLen ) 
<DIV></DIV>&gt; { 
<DIV></DIV>&gt; var token = ""; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; curChar = strFormat.charAt(i); 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; while (( strFormat.charAt(i) == curChar ) &amp;&amp; ( i &lt; intFormatLen )) 
<DIV></DIV>&gt; token += strFormat.charAt(i++); 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; result += formatOptions ( token ); 
<DIV></DIV>&gt; } 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Now, a double single quote (2 in a row) needs to be grapped and passed on 
<DIV></DIV>&gt;as a single token. but not 3 in a row, the third should be part of the 
<DIV></DIV>&gt;next token. It needs to grab 2 adjacent at a time. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;If it finds one single quote, it needs to grab all characters until it 
<DIV></DIV>&gt;sees and other single quote. Yes, it needs to be able to handle an 
<DIV></DIV>&gt;embedded pair of single quotes. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;So, if I have this... 
<DIV></DIV>&gt; 
<DIV></DIV>&gt; EEEE 'is walter''s birthday' 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;This should give me 3 tokens 
<DIV></DIV>&gt; 1) EEEE 
<DIV></DIV>&gt; 2) a SPACE 
<DIV></DIV>&gt; 3) is walter's birthday 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I can grab all but #3! :( 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;I have been banging my head for 3 days on this one, I just can't see it. 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Help? 
<DIV></DIV>&gt; 
<DIV></DIV>&gt;Walter
