data extraction from xml file

I have an of xml file as shown below

Code:

<?xml version='1.0' encoding='ASCII' standalone='yes' ?>
<Station Index="10264" >
   <Number Value="237895890" />

            1850
            1964
         </Temperature>
         <Salinity Count="12" >
            3576
            3583
            3573

            3562
            3577
         </Salinity>

The temp gives me the temp for 12 months and salinity for 12 months. the file runs till 752 lines

Question : I want to extract some specific data (depth ,Temp and salinity) from the file i.e temp of 1st month (i.e first value in temp), corresponding salinity in tht month(i.e first value in salinity)

Code:

depth     temp    salinity
    0          2183     3577
    10        xxxxxx   xxxxx
    20        yyyyyy   yyyyyy
etc

to a file

My idea : Temp :- is starting from Line 10 for depth 0 and from line 41 for depth to and so on, so 31 lines diff bw them. and similarly for Salinity and similarly for depth - using awk and for loop for data extraction. Will this work ?. or any other ideas to implement this

I have attached the xml file for reference

desktop_color_depth

desktop_color_depth(3alleg4)					  Allegro manual				      desktop_color_depth(3alleg4)

NAME

       desktop_color_depth - Finds out the desktop color depth. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int desktop_color_depth();

DESCRIPTION

       Finds  out  the	currently  selected desktop color depth. You can use this information to make your program use the same color depth as the
       desktop, which will likely make it run faster because the graphic driver won't be doing unnecessary color conversions behind your back.

       Under some OSes, switching to a full screen graphics mode may automatically change the desktop color depth. You have,  therefore,  to  call
       this function before setting any graphics mode in order to retrieve the real desktop color depth. Example:

	  allegro_init();
	  ...
	  if ((depth = desktop_color_depth()) != 0) {
	     set_color_depth(depth);
	  }

RETURN VALUE

       Returns the color depth or zero on platforms where this information is not available or does not apply.
