How to match string in more than one line using Regex

Oct 24 2006 3:02 AM

Hi all,

I need to match string from {=BeginCatRecords=} to {=EndCatRecords=}....

Here is the HTML code from a file (categories.html), I a reading in a variable st :

<TABLE width="100%" border="0" align="center" cellpadding="0" cellSpacing=0 >
 <TR valign="top" >
  {=BeginCatRecords=}<TD width="45%" align='center' style='border:1px #F4EED4 solid;'><Table align='center' border="0"><tr><td align='center' style="padding-top:15px;"><a href="{=CatLink=}"><IMG SRC="images/category/{=CatImg=}" border="0" width="150"></a><BR><a href="{=CatLink=}" class='catlinks'><strong>{=CatName=}</a></strong></td></tr><tr><td><table width="90%" border='0' align="center" cellpadding="0" cellSpacing=0><tr><td align='left'>{=CatDesc=}</td></tr></table></td></tr></table></td><td width='5%'>&nbsp;</td>{=EndCatRecords=}
 </TR>
 <TR><TD colspan='2'>&nbsp;</TD></TR>
</TABLE>

In this file, from {=BeginCatRecords=} to {=EndCatRecords=} is written in one line.. and it is working fine...

But if I split it in multiline like :

{=BeginCatRecords=}
<TD width="45%" align='center' style='border:1px #F4EED4 solid;'>
<Table align='center' border="0">
 <tr><td align='center' style="padding-top:15px;"><a href="{=CatLink=}"><IMG SRC="images/category/{=CatImg=}" border="0" width="150"></a><BR><a href="{=CatLink=}" class='catlinks'><strong>{=CatName=}</a></strong></td></tr><tr><td><table width="90%" border='0' align="center" cellpadding="0" cellSpacing=0><tr><td align='left'>{=CatDesc=}</td></tr></table></td></tr></table></td><td width='5%'>&nbsp;</td>
{=EndCatRecords=}

It stops working...

Below is the code I am using to match the string :

string NavMatch = null;
pattern = @"{=BeginCatRecords=}.*?{=EndCatRecords=}";
Match MatchTop = Regex.Match(st, pattern, RegexOptions.Multiline);
NavMatch = MatchTop.ToString();


I suppose, I need to change either the pattern or I am missing any option while matching the string...

If you have any other logic to do the needful, please let me know..

Please help..
