Hello, I have complex XML file (around 1000 of records) and need to retrieve few elements based on the condition...

1.want to read node only where ciType="application"

2.read the value of entry where key="Last Status Change" o/p:10/2/2017 10:16 PM

<nodes> <node name="ABC" id="1" ciType="null"> <children> <node name="Business Systems" classification="null" ciType +="ci_collection"> <dimension name="Unresolved Events" status="-2" id +="3232"> </dimension> <dimension name="Availability" status="10" id="123 +13"> </dimension> <children> <node name="3YP (421)" classification="null" ciTyp +e="application" > <dimension name="Availability" status="20" + id="2312"> <body> <entry key="Status"> <![CDATA[ OK ]]> </entry> <entry key="Business Rule"> <![CDATA[ Percentage Rule ]]> </entry> <entry key="Last Status Change"> <![CDATA[ 10/2/2017 10:16 PM ]]> </entry> </body> </dimension> </node> </children> </node> </children> </node> </nodes>

sample code

#!/usr/bin/perl use strict; use warnings; use XML::XPath; use XML::LibXML::NodeList; use Data::Dumper; my @records; my $bamxml = 'OpenApi.xml'; my $bamxp = XML::XPath->new(filename => $bamxml); my $bamxpath = $bamxp->findnodes('//nodes/node/children/node/chil +dren/node'); my $pattern = shift; my $matches = XML::LibXML::NodeList->new; foreach my $bamnode ($bamxpath->get_nodelist) { my $name = $bamxp->find('./@name',$bamnode)->string_value; my $citype = $bamxp->find('./@ciType',$bamnode)->string_va +lue; my $status = $bamxp->find('./dimension/@status',$bamnode)->str +ing_value; my $time = $bamxp->find("./dimension/body/entry",$bamnode)->st +ring_value; s/^\s+|\s+$//g for $name,$citype,$status,$time; push @records, { name => $name, citype => $citype, status => $status, Time => $time }; }

Required Output

$VAR1 = [ { 'status' => '20', 'citype' => 'application', 'name' => '3YP (421)', 'Time' => '10/2/2017 10:16 PM' } ];
