Doxygen and add a value of an attribute to the output documentation

Question

ServiceStack marks rest paths for web services using c# attributes.

For example

[RestService("/hello1")]
[RestService("/hello2")]
public class Hello

I would like to make Doxygen include values of the RestService attribute in the doxygen output for the Hello class. I'm not concerned too much with pretty formattin if the full line with brackets is included in the output document.

Any suggestions?

A quick and dirty trick would be a preferable to writing a Doxygen extension ;)

Cheers

====EDIT

The Python version (so will work on Windows easily) of doxygen user's answer would be:

#!/usr/bin/env python
import sys
import re

if (len(sys.argv) < 2):
    print "No input file"
else:
    f = open(sys.argv[1])
    line = f.readline()
    while line:
        re1 = re.compile("\[RestService\(\"(.*)\",.*\"(.*)\"\)]")
        re1.search(line)
        sys.stdout.write(re1.sub(r"/** \\b RestService: \2 \1\\n */\n", line))
        #sys.stdout.write(line)
        line = f.readline()
    f.close()

and the DOXYFILE would have:

INPUT_FILTER           = "doxygenFilter.py"

You could make an input filter that converts a line with

[RestService("/hello1")]

to

/** \b RestService: "/hello1"\n */

like for instance by putting following piece of perl magic in a file called filter.pl:

open(F, "<", $ARGV[0]);
while(<F>) { /^\s*\[RestService\((.*)\)\]\s*$/ ? 
             print "/** \\b RestService: $1\\n */\n" : print $_; }

and use that with the INPUT_FILTER tag in the Doxyfile:

INPUT_FILTER           = "perl filter.pl"
