Remove space before a character

Hi guys,

I am new to shell scripting and I have a small problem...If someone can solve this..that would be great

I am trying to form a XML by reading a flat file using shell scripting
This is my shell script

Code:
LINE_FILE1=`cat FLEX_FILE1.TXT | head -1 | tail -1`
echo '<PolicyNumber>'${LINE_FILE1:16:12}'</PolicyNumber>' >>$XML_FILE

16 is the start position of the policy number in the flat file and 12 is the number of characters. Policy number is just 5 characters The result I am getting as below
Code:
<PolicyNumber>12345 </PolicyNumber>

There is a space coming after the end of policy number (ie., at 6th position), even though I have seven more spaces in the flat file.

I want to remove this space.

If someone could answer that would be really helpful.

Thanks

__________________________________________________________________________________________________________________________________________________

NAME
platform::shell - System identification support code and utilities SYNOPSIS
package require platform::shell ?1.1.4? platform::shell::generic shell platform::shell::identify shell platform::shell::platform shell _________________________________________________________________ DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell. This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only requirement is that the other shell (identified by its path), is actually executable on the current machine. While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run 32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers. For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed packages, versus the architecture of the shell running the repository software. COMMANDS
platform::shell::identify shell This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell. platform::shell::generic shell This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell. platform::shell::platform shell This command returns the contents of tcl_platform(platform) for the specified Tcl shell. KEYWORDS
operating system, cpu architecture, platform, architecture platform::shell 1.1.4 platform::shell(3tcl)
