<\*?font # Match start of Font Tag
(?(?=[^>]+color.*>) #IF/THEN lookahead color in tag
(.*?color\s*?[=|:]\s*?) # IF found THEN move ahead
('+\#*?[\w\s]*'+ # CAPTURE ColorName/Hex
|"+\#*?[\w\s]*"+ # single or double
|\#*\w*\b) # or no quotes
.*?> # & move to end of tag
|.*?> # ELSE move to end of Tag
) # Close the If/Then lookahead
# Use Multiline and IgnoreCase
# Replace the matches from RE with MatchEvaluator below:
# if m.Groups(1).Value<>"" then
# Return "<font color=" & m.Groups(1).Value & ">"
# else
# Return "<font>"
# end if |
| Description |
This RE and MatchEvaluator will remove everything from inside HTML font tags EXCEPT the color declaration. (For ex: allow users to upload HTML content to site without their font tags overridding the font styles set in the CSS, except for the ability to change the font color for special emphasis.)
This works with color declarations using single quotes, double quotes, no quotes, color-names (red, black), Hex colors (#669933), and inline Style declarations inside a font tag. Does not work with inline Style declarations inside other tags like DIV, SPAN, or P (although it could be expanded to include those as well). |
| Matches |
<font size=5 color=black face=Arial> | <font style="font-family:arial;color:red"& |
| Non-Matches |
<DIV style="font-family:arial;color:red"> | <SPAN style="color:red"> |

| Description |
This regex is designed to parse entries from tnsnames.ora for Oracle connections. This is a crude first cut in that it doesn't allow for multiple ADDRESS entries in the ADDRESS_LIST section, and I don't know if there are other attributes that I should be allowing for. Basically, I just don't know enough about possible scenarios at this time, so I just wrote it to what I see in the wild where I work. |

(?<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 |
