Many thanks to all ( esp. mirod ) - this was *extremley* usefull info.
To refine my origional request, I wanted to see elements ( with their attributes ) and any corresponding values ( but with no recursion ) - if such values exist.
( This is because the element attributes themselves sometimes contain 'data' by their very name / existance )
My finished code, with an example of requirement / result :
foreach my $file ( @filelist ) {
my $twig= new XML::Twig();
$twig->parsefile($file);
my $twig_root = $twig->root;
foreach my $xpath_arg ( @xpath_args ) {
my @xpath_result = $twig_root->get_xpa
+th($xpath_arg);
foreach ( @xpath_result ) {
print &complete_path($
+_);
$_->contains_only_text
+ ? print ' : ' . $_->text . "\n" : print "\n";
}
}
}
sub complete_path() {
my( $elt )= @_;
return '/' . join( '/', map { tag_desc($_) } reverse $elt->anc
+estors_or_self);
}
sub tag_desc {
my( $elt )= @_;
my %atts= %{$elt->atts};
my $atts= %atts ? '[' . join( " ", map { qq{$_="$atts{$_}"} }
+ sort keys %atts) . ']' : '';
return $elt->tag . $atts;
}
Running : ./show_xpath_value.pl -x '//*[@keep="1"]'
/doc/elt[att1="1" keep="1"]
/doc/elt[att1="1" keep="1"]/elt2[att2="2" keep="1"] : foo
/doc/elt[att1="1"]/elt2[att2="2" keep="1"] : bar2
/doc/elt[att1="1" keep="1"]
/doc/elt[att1="1" keep="1"]/elt2[att2="2" keep="1"] : foo3
/doc/elt[att1="1" keep="1"]/elt2[att2="2" keep="1"] : bar3
Giving me just what I wanted !
Thanks again. |
