The process which reads, basically creates FIFO using
mkfifo - ret_val = mkfifo(HALF_DUPLEX, 0666);) func.

...it returns "20110429"

xml::parser::style::tree5.18
Parser::Style::Tree(3) User Contributed Perl Documentation Parser::Style::Tree(3) NAME
XML::Parser::Style::Tree SYNOPSIS
use XML::Parser; my $p = XML::Parser->new(Style => 'Tree'); my $tree = $p->parsefile('foo.xml'); DESCRIPTION
This module implements XML::Parser's Tree style parser. When parsing a document, "parse()" will return a parse tree for the document. Each node in the tree takes the form of a tag, content pair. Text nodes are represented with a pseudo-tag of "0" and the string that is their content. For elements, the content is an array reference. The first item in the array is a (possibly empty) hash reference containing attributes. The remainder of the array is a sequence of tag- content pairs representing the content of the element. So for example the result of parsing: <foo><head id="a">Hello <em>there</em></head><bar>Howdy<ref/></bar>do</foo> would be: Tag Content ================================================================== [foo, [{}, head, [{id => "a"}, 0, "Hello ", em, [{}, 0, "there"]], bar, [ {}, 0, "Howdy", ref, [{}]], 0, "do" ] ] The root document "foo", has 3 children: a "head" element, a "bar" element and the text "do". After the empty attribute hash, these are represented in it's contents by 3 tag-content pairs. perl v5.18.2 2011-05-24 Parser::Style::Tree(3)
