Nekomata is a library for constructing well-formed XML/HTML document. It is based on SimpleXMLElement.
See this example for a full atom feed example and this example for a full XHTML+RDFa example.
A simple XML document:
<?php
$doc = Nekomata::create(array('qualified_name' => 'NameOfYourRootNode'));
header('Content-Type: text/xml');
$doc->render('php://output');Result:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<NameOfYourRootNode/>Sample of identi.ca's FOAF document:
<?php
$doc = Nekomata::create(array(
'qualified_name' => 'rdf:RDF',
'namespaces' => array(
'_' => 'http://xmlns.com/foaf/0.1/',
'rdf' => 'http://www.w3.org/1999/02/22-rdf-syntax-ns#',
'rdfs' => 'http://www.w3.org/2000/01/rdf-schema#',
'geo' => 'http://www.w3.org/2003/01/geo/wgs84_pos#',
'bio' => 'http://purl.org/vocab/bio/0.1/',
'sioc' => 'http://rdfs.org/sioc/ns#'
)
));
$doc
