<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Hi <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>I want to
use backward reference in ragel regular expression for creating parser for my
language. The requirement is kind of begining and end of tag matching where tag
can be any arbitary string. e.g<o:p></o:p></span></font></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><font
size=3 face="Times New Roman"><span style='font-size:12.0pt'>1./test/ this is
sample /test/ <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>or it can
be <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>2./hello/
this is test /hello/ <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>and
following can be consider as a invalide<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>3./abc/
this is invalid /xyz/ <o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>So as in
above example tag can be any arbitary string but requirement is to match
begining and ending tag string should be same. To write regular expression for
above requirement in ragel language i want to use backward reference as in
javascript. So can somebody give valuable suggestion how can we achieve it in
ragel or any pointer related to same would be great help<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Thanks
& Regards<o:p></o:p></span></font></p>
