AWK to Parse XML messages
Hello Guys,

Please help with AWK problem. I have XML file which contains a list of messages for subjects.



Example of the messages:

Code:
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”English” Status=”P”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”Science” Status=”F”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”Science” Status=”F”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”Science” Status=”NA”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”English” Status=”P”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”English” Status=”F”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”Maths” Status=”P”>
[date+time], message=[DATA= “<?xml version=”1.0?”><data changeMsg><Subject=”Science” Status=”P”>


I want to use AWK to parse these xml messages but I am new to awk and to programming.

What I want is to get output of these messages to look like this.


Output


Code:
Subject|Status|Count
  English|P|2
  Science|F|2
  Science|NA|1
  English|F|1
  Maths|P|1
  Science|P|1


Please Help.


Thanks all for any help.

merge_fonts

merge_fonts(3alleg4)						  Allegro manual					      merge_fonts(3alleg4)

NAME

       merge_fonts - Merges two fonts into one font. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       FONT *merge_fonts(FONT *f1, FONT *f2)

DESCRIPTION

       This function merges the character ranges from two fonts and returns a new font containing all characters in the old fonts. In general, you
       cannot merge fonts of different types (eg, TrueType fonts and bitmapped fonts), but as a special case, this function can  promote  a  mono-
       chrome bitmapped font to a color font and merge those. Example:

	  FONT *myfont;
	  FONT *myfancy_font;
	  FONT *lower_range;
	  FONT *upper_range;
	  FONT *capitals;
	  FONT *combined_font;
	  FONT *tempfont;
	  ...
	  /* Create a font that contains the capitals from  */
	  /* the fancy font but other characters from myfont */
	  lower_range = extract_font_range(myfont, -1, 'A'-1);
	  upper_range = extract_font_range(myfont, 'Z'+1, -1);
	  capitals = extract_font_range(myfancy_font, 'A', 'Z');

	  tempfont = merge_fonts(lower_range, capitals);
	  combined_font = merge_fonts(tempfont, upper_range);

	  /* Clean up temporary fonts */
	  destroy_font(lower_range);
	  destroy_font(upper_range);
	  destroy_font(capitals);
	  destroy_font(tempfont);

RETURN VALUE

       Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
       to avoid memory leaks.
