Re: XML parsing

This does nearly what you want:

use strict;
use XML::Simple;

my $xml = <<EOX;
<FinInstnCdtTrf>
<GrpHdr>
<MsgId>0000003714</MsgId>
<CreDtTm>2013-03-04T16:01:57</CreDtTm>
<NbOfTxs>1</NbOfTxs>
<TtlIntrBkSttlmAmt Ccy="INR">234.00</TtlIntrBkSttlmAmt>
<IntrBkSttlmDt>2013-02-05</IntrBkSttlmDt>
<SttlmInf>
<SttlmMtd>CLRG</SttlmMtd>
</SttlmInf>
<InstgAgt>
<FinInstnId>
<ClrSysMmbId>
<MmbId>HOMEMEMEBER</MmbId>
</ClrSysMmbId>
</FinInstnId>
</InstgAgt>
<InstdAgt>
<FinInstnId>
<ClrSysMmbId>
<MmbId>FOREIGNMEMBER</MmbId>
</ClrSysMmbId>
</FinInstnId>
</InstdAgt>
</GrpHdr>
</FinInstnCdtTrf>
EOX

sub parsetree {
    my $ref = shift;
    my $txt = shift;
    foreach my $key ( keys %{$ref} ) {
    if( ref( $$ref{$key} ) =~ /HASH/ ) {
        parsetree( $$ref{$key}, $txt."::".$key );
    } else {
        print $txt."::".$key."::".$$ref{$key}."\n";
    }
    }
}
parsetree(XMLin($xml));

Output:

A quick and dirty fix is to just strip off any leading "`::`" before printing: `sub parsetree { my $ref = shift; my $txt = shift; foreach my $key ( keys %{$ref} ) { if( ref( $$ref{$key} ) =~ /HASH/ ) { parsetree( $$ref{$key}, $txt."::".$key ); } else { my $out = $txt . '::' . $key . '::' . $$ref{$key} . "\n"; $out =~ s/^:://; print $out; } } }` [download] This will produce (Update: closer to) the requested output, so long as "order" doesn't matter.

There is one more difference to the requested output. The currency (INR) and the amount (234.00) are given as separate lines. This results from the way XML::Simple deals with <tag name=value>.	[reply]
