Perl script to parse XML using XML::LibXML;

libxml2, perl, xml

Solution

You have the right method for getting the tag names, you just need an extra loop to run through the tags inside each `<sample>`:

#!/usr/bin/perl

use strict;
use warnings;

use XML::LibXML;

my $filename = "data.xml";

my $parser = XML::LibXML->new();
my $xmldoc = $parser->parse_file($filename);

for my $sample ($xmldoc->findnodes('/Statistics/Stats/Sample')) {
    for my $property ($sample->findnodes('./*')) {
        print $property->nodeName(), ": ", $property->textContent(), "\n";
    }
    print "\n";
}

Edit: I have now created a tutorial site called Perl XML::LibXML by Example which answers exactly this type of question.

Problem

I think this is a very simple issue, but I cannot figure it out despite many searches. I am trying to parse the following XML to print something similar to TAG=VALUE, so that I can write this to a CSV file. The problem is the tags are not always the same for each sample. I cannot seem to figure out how to get the actual tag names. Any help appreciated!!! XML File - ``` <Statistics> <Stats> <Sample> <Name>System1</Name> <Type>IBM</Type> <Memory>2GB</Memory> <StartTime>2012-04-26T14:30:01Z</StartTime> <EndTime>2012-04-26T14:45:01Z</EndTime> </Sample> <Sample> <Name>System2</Name> <Type>Intel</Type> <Disks>2</Disks> <StartTime>2012-04-26T15:30:01Z</StartTime> <EndTime>2012-04-26T15:45:01Z</EndTime> <Video>1</Video> </Sample> </Stats> </Statistics> ``` Script - ``` #!/usr/bin/perl use XML::LibXML; $filename = "data.xml"; my $parser = XML::LibXML->new(); my $xmldoc = $parser->parse_file($filename); for my $sample ($xmldoc->findnodes('/Statistics/Stats/Sample')) { print $sample->nodeName(), ": ", $sample->textContent(), "\n"; } ```
