I thought you said you had an XML file.
That is not a valid XML file...
I need to extract the DATA part of the xml structure
Note : tag3 can be contained either within tag1 or tag2, but I need to
extract data only from tag1. i.e. DATA1 should be extracted, but not
DATA2
If I want to get both DATA1 and DATA2 I can use a simple regex like :
Using a regular expression to "parse" a non-regular language is
fraught with peril, and nearly always a Bad Idea.
Use a module that understands XML for processing XML data.
Any help would be appreciated !
Assuming that you have actual valid XML in $xml, then:
use XML::Simple;
my $ref = XMLin($xml);
foreach my $child ( @{ $ref->{tag1} } ) {
print "$child->{tag3}\n";
