NAME

XML::Mini - Perl implementation of the XML::Mini XML create/parse interface.

SYNOPSIS

         use XML::Mini::Document;
         
         use Data::Dumper;
         
         
         ###### PARSING XML #######
         
         # create a new object
         my $xmlDoc = XML::Mini::Document->new();
         
         # init the doc from an XML string
         $xmlDoc->parse($XMLString);
         
         # You may use the toHash() method to automatically
         # convert the XML into a hash reference
         my $xmlHash = $xmlDoc->toHash();
         
         print Dumper($xmlHash);
         
         
         # You can also manipulate the elements like directly, like this:        
         
         # Fetch the ROOT element for the document
         # (an instance of XML::Mini::Element)
         my $xmlRoot = $xmlDoc->getRoot();
         
         # play with the element and its children
         # ...
         my $topLevelChildren = $xmlRoot->getAllChildren();
         
         foreach my $childElement (@{$topLevelChildren})
         {
                 # ...
         }
         
         
         ###### CREATING XML #######
         
         # Create a new document from scratch
         
         my $newDoc = XML::Mini::Document->new();
         
         # This can be done easily by using a hash:
         my $h = {       
          'spy'  => {
                 'id'    => '007',
                 'type'  => 'SuperSpy',
                 'name'  => 'James Bond',
                 'email' => 'mi5@london.uk',
                 'address'       => 'Wherever he is needed most',
                 },
         };
 
         $newDoc->fromHash($h);
  
         
         
         # Or new XML can also be created by manipulating 
         #elements directly:
         
         my $newDocRoot = $newDoc->getRoot();
         
         # create the <? xml ?> header
         my $xmlHeader = $newDocRoot->header('xml');
         # add the version 
         $xmlHeader->attribute('version', '1.0');
         
         my $person = $newDocRoot->createChild('person');
         
         my $name = $person->createChild('name');
         $name->createChild('first')->text('John');
         $name->createChild('last')->text('Doe');
         
         my $eyes = $person->createChild('eyes');
         $eyes->attribute('color', 'blue');
         $eyes->attribute('number', 2);
         
         # output the document
         print $newDoc->toString();
 
 

This example would output :

  <?xml version="1.0"?>
   <person>
    <name>
     <first>
      John
     </first>
     <last>
      Doe
     </last>
   </name>
   <eyes color="blue" number="2" />
   </person>
 
 

DESCRIPTION

XML::Mini is a set of Perl classes that allow you to access XML data and create valid XML output with a tree-based hierarchy of elements. The MiniXML API has both Perl and PHP implementations.

It provides an easy, object-oriented interface for manipulating XML documents and their elements. It is currently being used to send requests and understand responses from remote servers in Perl or PHP applications. An XML::Mini based parser is now being tested within the RPC::XML framework.

XML::Mini does not require any external libraries or modules and is pure Perl. If available, XML::Mini will use the Text::Balanced module in order to escape limitations of the regex-only approach (eg ``cross-nested'' tag parsing).

The Mini.pm module includes a number of variables you may use to tweak XML::Mini's behavior. These include:

$XML::Mini::AutoEscapeEntities - when greater than 0, the values set for nodes are automatically escaped, thus $element->text('4 is > 3') will set the contents of the appended node to '4 is > 3'. Default setting is 1.

$XML::Mini::IgnoreWhitespaces - when greater than 0, extraneous whitespaces will be ignored (maily useful when parsing). Thus <mytag> Hello There </mytag> will be parsed as containing a text node with contents 'Hello There' instead of ' Hello There '. Default setting is 1.

$XML::Mini::CaseSensitive - when greater than 0, element names are treated as case sensitive. Thus, $element->getElement('subelement') and $element->getElement('SubElement') will be equivalent. Defaults to 0.

Class methods

escapeEntites TOENCODE

This method returns ToENCODE with HTML sensitive values (eg '<', '>', '"', etc) HTML encoded.

Log MESSAGE

Logs the message to STDERR

Error MESSAGE

Logs MESSAGE and exits the program, calling exit()

ignoreDeepRecursionWarning

XML::Mini uses deep recursion on big XML docs, this is normal. But the warnings are a pain. $XML::Mini::IgnoreDeepRecursionWarnings is set to TRUE by default, and ignoreDeepRecursionWarning() is called by XML::Mini::Document if it is set. To bypass this behavior,

         use XML::Mini;
         
         $XML::Mini::IgnoreDeepRecursionWarnings = 0;
         
         use XML::Mini::Document;
         
         # ...
