Here's a script which I have created so that I can fetch the contents of particular news article using HTML::TreeBuilder::XPath module to create a XML file. However, I can't get it to get the html tags when using findvalue method.

#!/usr/bin/perl -w             

use HTML::LinkExtor;           
use LWP::Simple;
use HTML::TreeBuilder::XPath;  
use Term::ProgressBar;


my $url = "http://www.totalpolitics.com/blog/463546/senior-medics-call
+-on-uk-to-stay-but-brexiteers-have-more-to-cheer.thtml";
my $content = get $url;

my $tree = HTML::TreeBuilder::XPath->new_from_content($content); 

my $title = $tree->findvalue(q{//div[@id="article"]/h1});
my $body = $tree->findvalue(q{//div[@class="article-body"]});
my $author = $tree->findnodes(q{//div[@class="article-body"]/p/strong}
+);
$author = $author->[0]->getValue;

$body =~ s/$author//;

my $xml .= '<?xml version="1.0" encoding="UTF-8" ?>';
$xml .= '<nodes>';
$xml .= '<node>';
$xml .= '<url>';
$xml .= $url;
$xml .= '</url>';
$xml .= '<title>';
$xml .= $title;
$xml .= '</title>';
$xml .= '<description>';
$xml .= "<![CDATA[$body]]>";
$xml .= '</description>';
$xml .= '<author>';
$xml .= $author;
$xml .= '</author>';
$xml .= "</node>\n";
$xml .= "</nodes>";

print $xml;

      <title>Senior medics call on UK to stay - but Brexiteers have mo
+re to cheer</title>
      <description><![CDATA[The referendum battle steps up today with 
+the Remain camp offering up a consortium of medics – but other interv
+entions suggest the Brexiteers may have more to cheer in the weeks to
+ come.A group of 188 clinicians, academics and public health leaders 
+have written to the Times claiming the NHS would be in jeopardy if th
+e UK were to leave the EU, losing access to “finances, staffing and e
+xchanges”. They added:“As health professionals and researchers we wri
+te to highlight the valuable benefits of continued EU membership to t
+he NHS, medical innovation and UK public health. We have made enormou
+s progress over decades in international health research, health serv
+ices innovation and public health. Much of this is built around share
+d policies and capacity across the EU.”Britain Stronger In’s decision
+ to use medics is reflective of recent polling by Ipsos Mori, which s
+hows 89% trust doctors to tell the truth, making them the most truste
+d profession in the UK. Politicians languish at the bottom of the lea
+gue table on 21%.However the intervention may pale into insignificanc
+e after Brexiteers won an important battle to reveal the true number 
+of European migrants working in Britain. The number of migrants with 
+active national insurance (NI) numbers will now be released just week
+s before the referendum.According to existing data, about 800,000 EU 
+migrants have moved to the UK in the past four years. However over th
+e same period about 2m EU migrants have been issued with NI numbers.C
+ampaigners have long been calling upon the government to release figu
+res for the number of people with active NI numbers, which they say w
+ill provide a more accurate gauge of migration levels than existing o
+fficial figures.Andrew Tyrie, chairman of the Treasury select committ
+ee, said: “This has been obtained as a result of a good deal of persi
+stence … Late, but a good deal better than never. I recognise that HM
+RC may have encountered some difficulties. So I am glad that they hav
+e found a way of resolving them.”The decision comes as the Sun report
+s an extraordinary outburst from David Cameron as he returned from Wa
+shington this weekend.Asked whether the prime minister was so distrac
+ted by the referendum campaign that he had taken his eye off the ball
+, leading to a poorly-received budget and the crisis in the steel ind
+ustry, he replied:“I think you all spend too much time looking at eac
+h other’s newspapers. The world hasn't stopped turning, the Governmen
+t hasn't stopped operating. You all go around setting each others' ha
+ir on fire and getting very excited about this, but it's all a lot of
+ processology.”But new polling out today suggests the Leave campaign 
+has the more compelling set of arguments over Europe. The Fabian Soci
+ety research shows how an initial four-point leave for Remain among l
+ikely voters turns into a two-point lead for Leave once people heard 
+both sides of the story.Research found that the two most important is
+sues to deciding how people vote in the referendum are immigration an
+d controlling our laws – and on both issues the public are far more c
+onvinced that leaving the EU will help solve the problem.@Tom_Smithar
