I'm currently learning how to work with xml documents. I've got as far as finding out about XML::Simple and working though some examples. Here is my 'test script' as it is at the moment.
#!/usr/bin/perl
# use module
use XML::Simple;
use Data::Dumper;
$xs = new XML::Simple(keeproot => 1,searchpath => ".",
forcearray => 1,);
$ref = $xs->XMLin("test.xml");
print Dumper($ref);
And my data dump looks like this.
$VAR1 = {
'sas_residue_annotation' => [
{
'xmlns' => 'http://www.ebi.a
+c.uk/WSsas/Schema',
'sources' => [
{
'source' => [
{
+ 'source_name' => [
+ '1iho'
+ ],
+ 'ref_evalue' => [
+ '5.5e-50'
+ ],
+ 'ref_overlap' => [
+ '282'
+ ],
+ 'ref_identity' => [
+ '47.20'
+ ],
+ 'ref_pmid' => [
+ '11377204'
+ ]
}
+,
{
+ 'source_name' => [
+ '1mop'
+ ],
+ 'ref_evalue' => [
+ '8.3e-38'
+ ],
+ 'ref_overlap' => [
+ '264'
+ ],
+ 'ref_identity' => [
+ '43.60'
+ ],
+ 'ref_pmid' => [
+ '12717031'
+ ]
}
+,
{
+ 'source_name' => [
+ '1n2b'
+ ],
+ 'ref_evalue' => [
+ '8.2e-38'
+ ],
+ 'ref_overlap' => [
+ '264'
+ ],
+ 'ref_identity' => [
+ '43.60'
+ ],
+ 'ref_pmid' => [
+ '12717031'
+ ]
}
+,
etc ...
I'm not sure how to go about retrieving the information - how I might, for example, just want to print off all the 'source names' in my file. I've tried following a few examples on this today and haven't been able to figure it out yet.
Any tips much appreciated.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
