NAME

XML::TinyXML - Little and efficient Perl module to manage xml data.

SYNOPSIS

use XML::TinyXML;

# first create an XML Context
$xml = XML::TinyXML->new();
  
$node = XML::TinyXML::Node->new("nodelabel", "somevalue");
# or maybe 
$attrs = { attr1 => v1, attr2 => v2 };
$node = XML::TinyXML::Node->new("nodelabel", "somevalue", $attrs);

$xml->addRootNode($node);

# or you could want to create the XML Context 
# specifying the root node directly at creation time
$xml = XML::TinyXML->new($node);

# or maybe 
$xml = XML::TinyXML->new("rootnode", "somevalue", { attr1 => v1, attr2 => v2 });

# or we can just create an empty root node:
$xml = XML::TinyXML->new("rootnode");

# and then obtain a reference using the getNode() method
$node = $xml->getNode("/rootnode");

# the leading '/' is optional ... since all paths will be absolute and 
# first element is assumed to be always a root node
$node = $xml->getNode("rootnode");

# see XML::TinyXML::Node documentation for further details on possible
# operations on a node reference

# An useful facility is loading/dumping of hashrefs from/to xml
# for ex:
$hashref = { some => 'thing', someother => 'thing' };
my $xml = XML::TinyXML->new($hashref, 'mystruct');

# or to load on an existing XML::TinyXML object
$xml->loadHash($hashref, 'mystruct');

# we can also create and dump to string all at once :
my $xmlstring = XML::TinyXML->new($hashref, 'mystruct')->dump;

# to reload the hashref back
my $hashref = $xml->toHash;

DESCRIPTION

Since in some environments it could be desirable to avoid installing Expat, XmlParser and blahblahblah , needed by most XML-related perl modules,. my main scope was to obtain a fast xml library usable from perl (so with a powerful interface) but without the need to install a lot of other modules (or even C libraries) to have it working. Once I discovered XS I started porting a very little and efficent xml library I wrote in C some years ago.

The interesting part of porting it in perl is that now it's really easy to improve the interface and I was almost always pissed off of installing more than 10 modules to have a simple xml implementation.

  • new ($arg, $param, $attrs, $doctype)

  • addNodeAttribute ($node, $key, $value)

  • removeNodeAttribute ($node, $index)

  • addRootNode ($name, $val, $attrs)

  • dump ()

    Returns a stringified version of the XML structure represented internally

  • loadFile ($path)

    Load the xml structure from a file

  • loadHash ($hash, $root)

    Load the xml structure from an hashref (AKA: convert an hashref to an xml document)

  • toHAsh ()

    Dump the xml structure represented internally in the form of an hashref

  • loadBuffer ($buf)

    Load the xml structure from a preloaded memory buffer

  • getNode ($path)

    Get a node at a specific path.

    $path must be of the form: '/rootnode/child1/child2/leafnod' and the leading '/' is optional (since all paths will be interpreted as absolute)

    Returns an XML::TinyXML::Node object

  • getChildNode ($node, $index)

    Get the child of $node at index $index.

    Returns an XML::TinyXML::Node object

  • removeNode ($path)

    Remove the node at specific $path , if present. See getNode() documentation for some notes on the $path format.

    Returns XML_NOERR (0) if success, error code otherwise.

    See Exportable constants for a list of possible error codes

  • getBranch ($index)

    alias for getRootNode

  • getRootNode ($index)

    Get the root node at $index.

    Returns an XML::TinyXML::Node object if present, undef otherwise

  • removeBranch ($index)

    Remove the rootnode (and all his children) at $index.

  • getChildNodeByName ($node, $name)

    Get the child of $node with name == $name.

    Returns an XML::TinyXML::Node object if there is such a child, undef otherwise

  • save ($path)

    Save the xml document represented internally into $path.

    Returns XML_NOERR if success, a specific error code otherwise

EXPORT

None by default.
