Hello, I have to process an XML SELECTIVELY. Namely, if we have field firstname within title with different first letter as arguments, I want to print only those titles that DO NOT have first name with first letter 'A'. For that I use the following code:

use strict;
use XML::Twig;

my $sel = 'title';
my $ign = 'title/name/fnm[@letter="a"]';
my $twig = XML::Twig->new(
ignore_elts => { "$ign" => 1},
twig_roots  => { "$sel" => 1},
pretty_print => 'indented'
);

$twig->parsefile('1.xml');

$twig->print;

on the following XML:

<?xml version="1.0"?>
<titles>
<title id="1">testing<name><snm>Houston</snm>, <fnm letter="c">Carl</f
+nm></name><g>69</g><ppg>20.1</ppg><rpg>3.4</rpg><apg>2.8</apg><blk>14

<title id="2">testing<name><snm>Houston</snm>, <fnm letter="a">Allan</
+fnm></name><g>69</g><ppg>20.1</ppg><rpg>3.4</rpg><apg>2.8</apg><blk>1

<title id="3">testign

    <fnm j="b">Bob</fnm>

    <title>

        <title>

I am new to XML::Twig. I read about ignore_elts and I though it will do the job. It does, but not exactly what I want. So basically what I want is to ignore the whole title where the ignore condition is met:

<?xml version="1.0"?>
<titles>
  <title id="1">testing<name><snm>Houston</snm>, <fnm letter="c">Carl<
+/fnm></name><g>69</g><ppg>20.1</ppg><rpg>3.4</rpg><apg>2.8</apg><blk>
+14</blk></title>
  
  <title id="3">testign
    <name>Houston
    <fnm j="b">Beb</fnm><g>49</g><title>
    testing the sub title in title
    </title><title>
    this is pcdata in subtitle
        <title>
        second sub level
        </title></title></name></title>
</titles>

while what I get is (the title with id=2 is there but the fnm is missing):

<?xml version="1.0"?>
<titles>
  <title id="1">testing<name><snm>Houston</snm>, <fnm letter="c">Carl<
+/fnm></name><g>69</g><ppg>20.1</ppg><rpg>3.4</rpg><apg>2.8</apg><blk>
+14</blk></title>
  <title id="2">testing<name><snm>Houston</snm>, </name><g>69</g><ppg>
+20.1</ppg><rpg>3.4</rpg><apg>2.8</apg><blk>14</blk></title>
  <title id="3">testign
    <name>Houston
    <fnm j="b">Beb</fnm><g>49</g><title>
    testing the sub title in title
    </title><title>
    this is pcdata in subtitle
        <title>
        second sub level
        </title></title></name></title>

Any suggestions?
