Question

I am using Jenkins xml api with tree. Here is the url I am using for my locally hosted Jenkins server.

http://localhost:8080/api/xml?
   tree=jobs[name,description,color,healthReport[score,description]]

The above url shows me xml output as:

<hudson>
    <job>
        <description/>
        <name>build1</name>
        <color>disabled</color>
        <healthReport>
            <description>Build stability: 2 out of the last 5 builds failed.</description>
            <score>60</score>
        </healthReport>
    </job>
    <job>
        <description>test job description check.</description>
        <name>Build2</name>
        <color>blue</color>
        <healthReport>
            <description>Build stability: No recent builds failed.</description>
            <score>100</score>
        </healthReport>
    </job>
    <job>
        <description/>
        <name>Build3</name>
        <color>blue</color>
        <healthReport>
            <description>Build stability: 3 out of the last 4 builds failed.</description>
            <score>25</score>
        </healthReport>
    </job>
 </hudson>

Now I would like to parse the xml output in such a way that further I can process the tag values.

ex:

foreach job
if color=blue
print jobname : color 
if score = 100
etc

How could I do this in perl, which perl module should I use?

Start with:

use XML::LibXML qw( );
my $parser = XML::LibXML->new();
my $doc = $parser->parse_string($xml);
my $root = $doc->documentElement();

• foreach job

  for my $job ($root->findnodes('job'))
  

• if color=blu

  my $color = $job->findvalue('color/text()');
  

• print jobname : color

  my $job_name = $job->findvalue('name/text()');
  

• if score = 100

  my $score = $job->findvalue('healthReport/score/text()');
