Soap and entities

[anulaibar]

Does anyone know if php by automatically does htmlentities() on soap objects?
I got the following function that creates a soap object:

function insertNote(){
$soap = new SoapClient ("http://you.com/note.asmx?WSDL",
                        array ('exceptions' => 0,
                               'encoding' => 'UTF-8',
                               'trace' => 1));
$result = $soap->insertNote (array ('id' => $in['id'],
                          'noteText'   => $in['noteText']));				
}

The $in variable contains:

Array
(
    [id] => 21
    [noteText] => Me & you
)

But the in the soap-object the '&' has been replaced with '&':

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns1="http://me.com/">
  <SOAP-ENV:Body>
    <ns1:InsertNote noteText="Me  &amp; you"/>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Does anyone know why?

And so it should be: ampersands have a special meaning in XML, so to be treated literally they must be written as &.

http://www.w3.org/TR/2004/REC-xml-20040204/#syntax
The ampersand character (&) and the left angle bracket (<) MUST NOT appear in their literal form.... If they are needed elsewhere, they MUST be escaped using either numeric character references or the strings "&amp;" and "&lt;" respectively.

And I thought I should point out that it's not PHP doing it, but libxml.
