Multiple if within while loop ksh

Hi All,

I'm trying to write while loop with multiple if conditions. Each and every if condition with different variables. whenever one if condition fails i have remove the file
from filename and have to pick another file and loop should exit until the last file found in filename. Please help how to write a ksh shell script for that. Below i have given code what i tried

Thanks in advance.!!!

example:

Code:

#### here filename contain XXXX_YYYY_ZZZZ_DDD.txt as example
while read filename
#splitting a file without extension
full_filename=$filename
noextension=${full_filename%.*}
extension="${full_filename##*.}"

####assigning a patterns to different variable

echo "$noextension"|awk -F'_' '{ print NF-1 }' > countpattern

##### First fi######
if [ "$countpattern" -eq 5 ] ; then
A=$(echo $noextension|cut -d'_' -f1)
B=$(echo $noextension|cut -d'_' -f2)
C=$(echo $noextension|cut -d'_' -f3)
D=$(echo $noextension|cut -d'_' -f4)
E=$(echo $noextension|cut -d'_' -f5)
fi

####Second If########
if [ ! $extension=txt-a $A=HELP] || [ ! $extension=csv -a ! A =HELP ]
then
UPDATE TABLE ########################
rm full_filename
fi

####third if#####
if [ ! $C = "WE" ]
then
UPDATE TABLE ########################
rm full_filename
fi

LEARN ABOUT PHP

id3_get_version

ID3_GET_VERSION(3)							 1							ID3_GET_VERSION(3)

id3_get_version - Get version of an ID3 tag

SYNOPSIS

       int id3_get_version (string  $filename)

DESCRIPTION

       id3_get_version(3) retrieves the version(s) of the ID3 tag(s) in the MP3 file.

	If a file contains an ID3 v1.1 tag, it always contains a 1.0 tag, as version 1.1 is just an extension of 1.0.

PARAMETERS

	      o $filename
		- The path to the MP3 file  Instead of a filename you may also pass a valid stream resource

RETURN VALUES

	Returns  the  version  number  of  the ID3 tag of the file. As a tag can contain ID3 v1.x and v2.x tags, the return value of this function
       should be bitwise compared with the predefined constants ID3_V1_0, ID3_V1_1 and ID3_V2.

EXAMPLES

       Example #1

	      id3_get_version(3) example

	      <?php
	      $version = id3_get_version( "path/to/example.mp3" );
	      if ($version & ID3_V1_0) {
		  echo "Contains a 1.x tag
";
	      }
	      if ($version & ID3_V1_1) {
		  echo "Contains a 1.1 tag
";
	      }
	      if ($version & ID3_V2) {
		  echo "Contains a 2.x tag
";
	      }
	      ?>

	      The above example will output something similar to:

	      Contains a 1.x tag
	      Contains a 1.1 tag
