I am completely new to perl programming. My father is helping me learn said programming language. However, I am stuck on one of the assignments he has given me, and I can't find very much help with it via google, either because I have a tiny attention span, or because I can be very very dense.

xml_pp
XML_PP(1) User Contributed Perl Documentation XML_PP(1)NAME
xml_pp - xml pretty-printer
SYNOPSYS
xml_pp [options] [<files>]
DESCRIPTION
XML pretty printer using XML::Twig
OPTIONS
-i[<extension>]
edits the file(s) in place, if an extension is provided (no space between "-i" and the extension) then the original file is backed-up
with that extension
The rules for the extension are the same as Perl's (see perldoc perlrun): if the extension includes no "*" then it is appended to the
original file name, If the extension does contain one or more "*" characters, then each "*" is replaced with the current filename.
-s <style>
the style to use for pretty printing: none, nsgmls, nice, indented, record, or record_c (see XML::Twig docs for the exact description
of those styles), 'indented' by default
-p <tag(s)>
preserves white spaces in tags. You can use several "-p" options or quote the tags if you need more than one
-e <encoding>
use XML::Twig output_encoding (based on Text::Iconv or Unicode::Map8 and Unicode::String) to set the output encoding. By default the
original encoding is preserved.
If this option is used the XML declaration is updated (and created if there was none).
Make sure that the encoding is supported by the parser you use if you want to be able to process the pretty_printed file (XML::Parser
does not support 'latin1' for example, you have to use 'iso-8859-1')
-l loads the documents in memory instead of outputing them as they are being parsed.
This prevents a bug (see BUGS) but uses more memory
-f <file>
read the list of files to process from <file>, one per line
-v verbose (list the current file being processed)
-- stop argument processing (to process files that start with -)
-h display help
EXAMPLES
xml_pp foo.xml > foo_pp.xml # pretty print foo.xml
xml_pp < foo.xml > foo_pp.xml # pretty print from standard input
xml_pp -v -i.bak *.xml # pretty print .xml files, with backups
xml_pp -v -i'orig_*' *.xml # backups are named orig_<filename>
xml_pp -i -p pre foo.xhtml # preserve spaces in pre tags
xml_pp -i.bak -p 'pre code' foo.xml # preserve spaces in pre and code tags
xml_pp -i.bak -p pre -p code foo.xml # same
xml_pp -i -s record mydb_export.xml # pretty print using the record style
xml_pp -e utf8 -i foo.xml # output will be in utf8
xml_pp -e iso-8859-1 -i foo.xml # output will be in iso-8859-1
xml_pp -v -i.bak -f lof # pretty print in place files from lof
xml_pp -- -i.xml # pretty print the -i.xml file
xml_pp -l foo.xml # loads the entire file in memory
# before pretty printing it
xml_pp -h # display help
BUGS
Elements with mixed content that start with an embedded element get an extra
<elt><b>b</b>toto<b>bold</b></elt>
will be output as
<elt>
<b>b</b>toto<b>bold</b></elt>
Using the "-l" option solves this bug (but uses more memory)
