find replace a pattern and following characters in a word
Suppose that I have a string "one:#red two:#yellow three:#gr'een four:#blu^e" and I want to replace the pattern :# and the following characters in the word with nothing. The output string should look "one two three four" How can I do this with sed.
Some points to consider (a) the last word in the sentence. (b) the first word in the sentence and (c) I am processing non-english text, so I have special characters '^ in it (d) lets assume the separator string :# are not special characters.
Many thanks in advance.

Hi experts,
My file looks something like this.
abcXX4,7,234
abc,defg,45XX23,74,123
The number of commas left of the XX can vary. The question is how can I replace all the commas left of the 'XX' with an underscore?
abcXX4,7,234

NAME
malaga - natural-language word and sentence analysis
SYNOPSIS
malaga [-morphology|-syntax] [-quoted] [-input input] project-file
DESCRIPTION
Malaga is a development environment for natural-language grammars based on the Left-Associative Grammar formalism. Malaga grammars can be
used for automatic morphological and/or syntactic analysis.
The program malaga is Malaga's user interface for analysing word forms and sentences, displaying the results and finding bugs in a grammar.
malaga requires the name of a language-dependent project-file as a command-line argument.
If no command line options are given, malaga starts in interactive mode, and you can enter commands. If you are not sure about the name of
a command, use the command help to get an overview of all malaga commands.
If you want to quit malaga, enter the command quit.
See info Malaga for details.

-i[nput] input
Analyse a single word or sentence given as command line argument (only valid in morphology or syntax mode).
-m[orphology]

line). The analysis result are written to the standard output stream.
-q[uoted]
The input lines to be analysed are quoted (only valid in morphology or syntax mode).
