e.g.)
Symbolic or numeric strings such as "123" and "+/-" can be eliminated by
the regular expression '([\p{Digit}\p{Punct}])+'.

Logging strings such as 'error("System error occurred!")' can be eliminated by
the function name 'error'.

Defined strings such as '#define APP_NAME "World Wide Navi"' can be eliminated by
the preprocessor name 'define'.

SQL strings such as 'sqlStr = "select * from mytable"' can be eliminated by
the variable name 'sql'.

Constant strings such as 'const string = "KEY_NAME"' can be eliminated by
the modifier 'const'.

HTML style sheet strings such as '<SPAN style="color: red;"...' can be eliminated by
the attribute name 'style'.

e.g.)
Only alphabet strings such as "abc" and "XYZ" can be detected by
the regular expression '([a_zA_Z])+'.

Only warning strings such as 'warn("Duplicated data!")' can be detected by
the function name 'warn'.

Only included file strings such as '#include "wwnavi.h"' can be detected by
the preprocessor name 'include'.

Only command strings such as 'cmd = "copy /x "' can be detected by
the variable name 'cmd'.

Only static strings such as 'static string = "My Name"' can be detected by
the modifier 'static'.

Only HTML INPUT value strings such as '<INPUT value="Click Me"' can be detected by
the attribute name 'value'.

e.g.) 
The rule of the regular expression '[a-c]+' AND  
  (the function name 'printf' OR the preprocessor name 'include' OR  
   the variable name 'foo' OR the modifier 'static' OR 
   the attribute name 'name') 
  matches '"abc"', 'printf("a")', '#include "b"', 'char* foo="c"', 'static char* str="ac"', '<input name="ab"',  
  doesn't match '"de"', 'printf("Bye")', '#include "my.h"', 'char* foo="foo"', 'static char* str="App"', '<input name="go"'.
  
In most of cases you specify other parameters than regular expressions, 
you need set the regular expression '.*' (any literals).

1. The libraries listed higher have priority over lower ones.
   (e.g. 'Common' > 'Std' > 'Win32' > 'MFC' > 'User1')

2. The regular expression keyword have priority over '*(all data)'.
   (e.g. '[a-c]+' > '*(all data)')
    
3. The library priorities (1.) have priority over keyword priorities (2.).
   (e.g. '*(all data)' of 'Common' > '[a-c]+' of 'Std')
