RE: [PHP] How to build a XML DTD on the fly?

2005-11-18 Thread Jared Williams 
  
 The code below lacks the part where the folling DTD attribute is
 created: !ATTLIST document id ID #IMPLIED
 
 How can I create the above DTD attribute in the code below?
 
 ?php
 // Creates an instance of the DOMImplementation class 
 $oDomImp = new DOMImplementation;
 
 // Creates a DOMDocumentType instance
 $oDomDtd = $oDomImp-createDocumentType('document', null, null);
 
 // Creates a DOMDocument instance
 $oDom = $oDomImp-createDocument(, , $oDomDtd);
 
 // Set other properties
 $oDom-encoding = 'iso-8859-1';
 $oDom-standalone = true;
 
 // Create an empty element
 $oElement = $oDom-createElement('document', 'test'); 
 $oElement-setAttribute('id', '123'); // Append the element 
 $oDom-appendChild($oElement);
 
 // Retrieve and print the document
 echo $oDom-saveXML() . \n;
 
 echo TagName:  . $oDom-getElementById('123')-tagName;
 ?
 
 Now the code produces the following result:
 
 ?xml version=1.0 encoding=iso-8859-1 standalone=yes? 
 !DOCTYPE document document id=123test/document
 
 TagName:
 

There is no real standard for creating DTDs on the fly, and therefore 
libxml/DOM doesn't have any methods afaik.

The one method DOMElement::setIDAttribute() should work I think, but whilst PHP 
has the method, doesn’t seem todo anything. :/

DocumentType nodes are read-only in DOM thus cannot be built on the fly. 
Also notice that not all components, such as ATTLIST, even have a node type.


setIDAttribute - thats on the TODO list. Were some previous libxml 
issues to be resolved before that could be implemented (so it will be 
added, but require a minimum libxml2 version to work).

Can always use xml:id attributes for that purpose for now though.

setAttributeNS('http://www.w3.org/XML/1998/namespace', 'id', 'abc') doesn’t 
work either, getElementById() still fails.

It does work as long as you are using libxml2-2.6.22
