I'm not familiar with the syntax of churl, but assume that you can fetch the XML into a file to parse with awk. This is an example of one way to accomplish your task.

Code:

#!/usr/bin/env ksh

awk -v RS=">" '                      # we dont need closing tag mark; make it the record seperator
        /Percent/ {                    # data we are interested in has this field
                data = 0;
                gsub( " = ", "=" );             # easier to work with if there are no spaces round equal signs
                gsub( "\"", "" );               # for this case we dont expect blanks in the value so ditch quote marks
                for( i = 1; i < NF; i ++ )     # for each token that is var=value
                {
                        if( (x = split( $(i), a, "=" )) == 2 )   # split and save the value
                        {
                                data++;           # may not be necessary, but safe
                                var[a[1]] = a[2];
                        }
                }

                if( data )                    # if we saw data, print it
                {
                        printf( "%c %6.3f %6.3f%%\n", 65+idx, var["Price"], var["Percent"]);
                        idx++;
                }
        }' <current.xml

Change the printf() statement to print it in the format you need.

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
