=head1 DESCRIPTION |
49
|
|
|
|
|
|
|
|
50
|
|
|
|
|
|
|
XML::TreePP module parses an XML document and expands it for a hash tree. |
51
|
|
|
|
|
|
|
This generates an XML document from a hash tree as the opposite way around. |
52
|
|
|
|
|
|
|
This is a pure Perl implementation and requires no modules depended. |
53
|
|
|
|
|
|
|
This can also fetch and parse an XML document from remote web server |
54
|
|
|
|
|
|
|
like the XMLHttpRequest object does at JavaScript language. |

|
Or set C<'@'> to access attribute values like E4X, ECMAScript for XML. |
391

|
|
|

|
|
|
|

|
This module calls Carp::croak function on an error per default. |
404

This option makes all errors ignored and just returns. |

This makes parsing performance slow. |
416
