The xml package provides APIs to handle XML.

XML data

Most of the time, XML is used to hold data. In this case, a fully blown DOM api is too much overhead to work with the data. This is where the xml.Tree class comes in.

This example will print out a nicely formatted XML document:

use xml\{Tree, Node}; $t= new Tree('customer'); $t->root()->setAttribute('id', '6100'); $t->addChild(new Node('name', 'Timm Übercoder')); $t->addChild(new Node('email', 'uebercoder@example.com')); echo $t->getSource(INDENT_DEFAULT);

XSL Transformation

The DomXSLProcessor class uses LibXSLT and thus supports EXSLT features like user functions, callbacks, string functions, dynamic evaluation and more.

A simple example:

use xml\DomXSLProcessor; use xml\TransformerException; use util\cmd\Console; $proc= new DomXSLProcessor(); $proc->setXSLFile('test.xsl'); $proc->setXMLFile('test.xml'); try { $proc->run(); } catch (TransformerException $e) { // Handle } Console::writeLine($proc->output());

XPath queries

use xml\XPath; use util\cmd\Console; $xml= '<dialog id="file.open">  <caption>Open a file</caption>  <buttons>  <button name="ok"/>  <button name="cancel"/>  </buttons> </dialog>'; Console::writeLine((new XPath($xml))->query('/dialog/buttons/button/@name')));
