Hi Forum.
I was trying to search the following scenario on the forum but was not able to.

Hi. I need to delete a large number of files listed in a txt file. There are over 90000 files in the list. Some of the directory names and some of the file names do have spaces in them.

I have searched this forum for related posts but could not find one that fits mine. I have a shell script which removes all the XML tags including the text inside the tags from some 4 million XML files.

Hi,
I have a large number of subdirectories (>200), and in each of these directories there is a file with a name like "opp1234.dat".
I'd like to know how I could change the names of these files to say "out.dat" in all these subdirectories in one go.
Thanks! (5 Replies)

Tree::Simple::Visitor::LoadDirectoryTree(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::LoadDirectoryTree(3pm)NAME
Tree::Simple::Visitor::LoadDirectoryTree - A Visitor for loading the contents of a directory into a Tree::Simple object
SYNOPSIS
use Tree::Simple::Visitor::LoadDirectoryTree;
# create a Tree::Simple object whose
# node is path to a directory
my $tree = Tree::Simple->new("./");
# create an instance of our visitor
my $visitor = Tree::Simple::Visitor::LoadDirectoryTree->new();
# set the directory sorting style
$visitor->setSortStyle($visitor->SORT_FILES_FIRST);
# create node filter to filter
# out certain files and directories
$visitor->setNodeFilter(sub {
my ($item) = @_;
return 0 if $item =~ /CVS/;
return 1;
});
# pass the visitor to a Tree::Simple object
$tree->accept($visitor);
# the tree now mirrors the structure of the directory
DESCRIPTION
This visitor can be used to load a directory tree into a Tree::Simple hierarchy.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" and "setSortStyle"
methods to customize its behavior.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are created. The function is given the current directory or file being added to the
tree, and it is expected to return either true(1) of false(0) to determine if that directory should be traversed or file added to the
tree.
setSortStyle ($sort_function)
This method accepts a CODE reference as its $sort_function argument and throws an exception if it is not a code reference. This
function is used to sort the individual levels of the directory tree right before it is added to the tree being built. The function is
passed the the current path, followed by the two items being sorted. The reason for passing the path in is so that sorting operations
can be performed on the entire path if desired.
Two pre-built functions are supplied and described below.
SORT_FILES_FIRST
This sorting function will sort files before directories, so that files are sorted alphabetically first in the list followed by
directories sorted alphabetically. Here is example of how that would look:
Tree/
Simple.pm
Simple/
Visitor.pm
VisitorFactory.pm
Visitor/
PathToRoot.pm
SORT_DIRS_FIRST
This sorting function will sort directories before files, so that directories are sorted alphabetically first in the list followed
by files sorted alphabetically. Here is example of how that would look:
Tree/
Simple/
Visitor/
PathToRoot.pm
Visitor.pm
VisitorFactory.pm
Simple.pm
visit ($tree)
This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
The node value of the $tree argument (gotten by calling "getNodeValue") is considered the root directory from which we begin our
traversal. We use File::Spec to keep our paths cross-platform, but it is expected that you will feed in a valid path for your OS. If
the path either does not exist, or is not a directory, then an exception is thrown.
The $tree argument which is passed to "visit" must be a leaf node. This is because this Visitor will create all the sub-nodes for this
tree. If the tree is not a leaf, an exception is thrown. We do not require the tree to be a root though, and this Visitor will not
affect any nodes above the $tree argument.
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.
SEE ALSO
These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
module for more information.
