REGEX Parsing Problem

I am doing some pattern matching for HTML and am having
problems for one instance. The pattern is not working
when encountering a "||". You can see in the output
below. It is in the data variable. I am looking to have
the data section in the tag.

I am getting HTML in the form of <tag>data

ex
input <table><tr><td>hello</td></tr></table>
output tag = <table>
data =
tag = <tr>
data =
tag = <td>
data = hello
tag = </td>
data =
tag = </tr>
data =
tag = </table>
data =

Any help would be appreciated.

string htmlRegEx = @"(<[^\>|^\<]*[>]*)([^\<]*)";

rx = new Regex(htmlRegEx);
mc = rx.Matches(text);

foreach(Match m in mc)

data = m.Groups[2].Value.Trim();

The problem is in your character class "[^\>|^\<]". Character classes [...]
match any single character between the brackets. While the pipe character
usually signifies alternation in a Regex, it represents a literal pipe
character when used inside a character class. Also, you don't need to
escape the ">" or "<". Your character class should read "[^><]" instead,
making the Regex look like this:

(<[^><]*[>]*)([^<]*)
