For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Help on perl module

Posted by pop18 (pop18), 30 August 2007
Dear All,

I am new to perl... Please help me out to solve the issue.
I got the below program and the result print on the execution screen itself. I want to capture it in the same input xml file(abc.xml).

use XML::TreeBuilder;

my $xml="abc.xml";
my $root = XML::TreeBuilder->new ();

for my $group ($root->look_down ('_tag', 'author-group')) {
   my @auths = $group->look_down ('_tag', 'auth');
   my $newRoot = HTML::Element->new ('xxx');

   $_->detach () for @auths;
   $newRoot->push_content (@auths);
   $group->unshift_content ($newRoot);

print $root->as_XML;

Thanks in advance,

Immediate answer: Change

print $root->as_XML;


open (FHO,">abc.xml");
print FHO $root->as_XML;
close FHO;

HOWEVER ... if anything goes wrong, you are destroying your input fil eand I would preceed thos three lines with

rename 'abc.xml','abc.bak';
