I have this pattern
-Dim pattern As String = "<BOOKMARK[^>]*>"
-Dim m As Match = Regex.Match(RichTextBox1.Text, pattern)
How can I match this pattern but only in bold form? I am trying a non regualexp approach but I am getting 'object reference not set to an instance of the object. Any ideas what I am doing wrong?[code]

This is a pretty complex regular expression that returns an array of key/value pairs from a proprietary string of data. Here is sample of the data, in case the express can not be used in .Net and another method needs to be used.
0,"101"1,"12345"11,"ABC Company"12,"John Doe"13,"123 Main St"14,""15,"Malvern"16,"PA"17,"19355"19,"UPS"21,"10"22,"GND"23,""24,"082310"25,""26,"0.00"29,"1Z1235550300000645"30," PA 193 9-05"34,"6.55"37,"6.55"38,"8.05"65,"1Z1235550300000645"77,"10"96,""97,""98
If you look closely you see its key,"value",key,"value" The only guarantee on formatting is that each key value pair is separated by a comma, and each value will always be encased in double quotes. The main problem (the reason you cant explode it) is the poor choice of the previous coder to separate keys and values with the same character as the entries. Anyways, out of my hands. Here is a working PHP example.
function parseResponse($response) {
// split response into $key, $value pieces
preg_match_all("/(.*?),"(.*?)"/", $response, $m);

I'm trying to match exactly the following format:
+639201112222
09201112222
and this is all Ive tried so far:
(+63|0)?d{10}
the problem is that it match 2920111222 in 29201112222. How can i create a pattern that will match only the formats below?
+63XXXXXXXXXX
0XXXXXXXXXX
+63 or 0 plus 10 digit number only.where X are all digits from 0-9.

It seems up until now I've never used Regex, nor even heard of it. But once I did I realized how extremely useful this is. Having said, it's been 2 days since I've began looking into constructing my own patterns. My most recent being for decimals. Is the pattern I provided below "proper"? and are there also any improvements I could be making for a more efficient patter, which would minimize any possibility of a loophole? [code] So for my use, this is doing what it's supposed to being doing under every test I can through at it. But do mind the 0. and .0, I have a function to normalize these as they are proper, I just pad the left and right accordingly. I found most regex questions asked here..and yes I am doing this in vb.net so it fits. If not, then feel free to move this post somewhere else better suited for the topic of discussion.

I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)", RegexOptions.Singleline)
output = re.Replace(userName, "$2 $1")
So why doesn't the following code store "#Test##Person#" in output variable.
Dim output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)")
For Each Match As Match In re.Matches(userName)
output &= "#" & Match.ToString & "#"
