[phpXML] Re: Dealing with HTML entities

[<lu...@sa...>]

Hello,

Here is the piece of code.


  // List of entities to be converted.
  //
  // This array contains a list of entities to be converted when an XPath
  // expression is evaluated.
  //
  // ### People seem to think that &apos is a bad idea for charset ISO-8859-1 
  //var $entities = array ( "&" => "&amp;", "<" => "&lt;", ">" => "&gt;",
  //    "'" => "&apos;", '"' => "&quot;" );
  var $entities = array('&'=>'&amp;', '<'=>'&lt;', '>'=>'&gt;', '"'=>'&quot;');
  

That means that if I do

[....]<!CDATA[[<p>Hello world</p>]]>[...]

The rendering will be

&lt;p&gt;Hello world&lt;/p&gt;

And the browser will display 

<p>Hello world</p>

The easiest (but probably not the safiest) solution is to emplty $entities, I 
have no problem with that because until now I use xml.php/xpath.class.php to 
read XML files not to produce XML files, but I suppose that emptying $entities 
is a bad thing to do when it comes to output XML.
