php - Add DocType to exits DomDocument -


i have php class likes "extension_domdocument" , extends php "domdocument" class.

i create new object of extension_domdocument , add doctype object.

my code is:

// $this->data array convert array xml  $objcdom = new extension_domdocument('1.0', 'utf-8');  $objcdom->frommixed($this->data);

how can add doctype $objcdom?

thank you!

you can use the dom implementation create document type object. document type objects still dom nodes. can append them existing document.

class mydomdocument extends domdocument {}  $dom = new mydomdocument(); $implementation = new domimplementation(); $dom->appendchild($implementation->createdocumenttype('example')); $dom->appendchild($dom->createelement('foo'));  echo $dom->savexml();

output:

<?xml version="1.0"?> <!doctype example> <foo/>
