(\[(\w+)\s*(([\w]*)=('|")?([a-zA-Z0-9|:|\/|=|-|.|\?|&]*)(\5)?)*\])([a-zA-Z0-9|:|\/|=|-|.|\?|&|\s]+)(\[\/\2\]) |
| Description |
Peseudo-HTML code matcher. Allows for one parameter within the first tag (name is optional), the value of which can be optionally delimited by either double or single quotes. Uses backreferencing to ensure that the end and start tags match, and that any single or double quotes match. Very useful for web forums or any situation where users may be prompted to enter text for display on a webpage somewhere, as it can be quickly processed into HTML without allowing HTML to be specified within the input itself (which may pose a security risk). |

[link url="http://www.domain.com/file.extension?getvar=value&secondvar=value"]Link[/li |
| Non-Matches |
[a]whatever[/b] | [a var1=something var2=somethingelse]whatever[/a] | [a]whatever[a] |

(?<commentblock>((?m:^[\t ]*\/{2}[^\n\r\v\f]+[\n\r\v\f]*){2,})|(\/\*[\w\W]*?\*\/)) |
| Description |
This expression will match comment blocks in javascript, c, c++, etc
I wrote this as a named group called "commentblock", as I like to use it with other expressions.
It avoids single line comments or inline commented code (which are not considered comment "blocks") unless the comments are in a /* text */ comment style
could not create a multiline example in the matching examples, here is what I tried to enter
// Some text
//(must be two or more lines long and each line may only be preceded by whitespace)
|
| Matches |
/* Some text (may be any number of lines) */ |
| Non-Matches |
// Some text (only a single line) | Some code // comment here (even if next line has comment) | /* S |
