Thanks Johnson
I'm having a small issue.
I need to trim a, b, c, d both sides, I know that the command above trims the first trailing space but I also have a couple of spaces after the word.
Another thing
I'm just curious about this line "read q b"
I understand the read statement and the letter 'b' that appears to be the name of a variable.
But which is the use of 'q' ?

xml::normalize::libxml
XML::Normalize::LibXML(3pm) User Contributed Perl Documentation XML::Normalize::LibXML(3pm)
NAME
XML::Normalize::LibXML - simple whitespace striping functions
SYNOPSIS
use XML::Normalize::LibXML qw(trim xml_normalize xml_strip_whitespace);
$greeting=trim(" hallo world "); # returns "hallo world" xml_normalize($dom->getDocumentElement());
xml_strip_whitespace($dom->getDocumentElement());
DESCRIPTION
This module provides simple whitespace striping and text-node normalizing functions.
"trim($string)"
Returns the string with any whitespace occuring at its beginning or end removed.
"xml_normalize($dom)"
Puts all Text nodes in the full depth of the sub-tree underneath this Element into a normal form where only markup (e.g., tags, comments,
processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are no adjacent Text nodes. This can be
used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as
XPointer lookups) that depend on a particular document tree structure are to be used.
"xml_strip_whitespace($dom [,$include_attributes])"
Normalizes the subtree and trims whitespace from all Text nodes within the subtree. If the optional argument $include_attributes is defined
and non-zero, this function trims whitespace also from all Attribute nodes.
"xml_strip_element($node)"
Removes leading and trailing whitespace from a given element.
