What is there in an object representing a complexType element ?

["LEBUR Guillaume" <guillaume.lebur@justice.fr>]

Hi,
 
I have written a sample PHP Web Service whose WSDL looks like that :
 
[...]
<types><xsd:schema elementFormDefault="qualified"
targetNamespace="urn:cms">
 <xsd:element name="article">
 <xsd:complexType>
  <xsd:sequence>
   <xsd:element name="titre" type="xsd:string"/>

   <xsd:element name="texte">
    <xsd:complexType mixed="true">
        <xsd:sequence>
            <xsd:any namespace="http://www.w3.org/1999/xhtml";
processContents="lax"
                minOccurs="0" maxOccurs="unbounded"/>
        </xsd:sequence>
    </xsd:complexType>
  </xsd:element>

  </xsd:sequence>
  </xsd:complexType>
 </xsd:element>
[...]
<message name="publierRequest"><part name="parameters"
element="tns:article" /></message>
<message name="publierResponse"><part name="parameters"
element="tns:publierResponseType" /></message>
<portType name="cmsserverPortType">
 <operation name="publier"><input message="tns:publierRequest"/><output
message="tns:publierResponse"/></operation>
</portType>
<binding name="cmsserverBinding" type="tns:cmsserverPortType">
 <soap:binding style="document"
transport="http://schemas.xmlsoap.org/soap/http"/>
 <operation name="publier">
  <soap:operation soapAction="urn:cms#publier" style="document"/>
  <input><soap:body use="literal" namespace="urn:cms"/></input>
  <output><soap:body use="literal" namespace="urn:cms"/></output>
 </operation>
</binding>

The "texte" element of the "article" parameter contains xhtml code, this
is why I set it as a mixed complexType containing an unbounded sequence
with any type of element in it. An example of the XML code sent to the
soap server would look like this :
 
 
[...]
<article>
            <!-- a simple string -->
    <titre>Title</titre> 
            <!-- xhtml code -->
    <texte><a href="foo.com">This</a> is a text
<strong>sample</strong></texte> 
</article>
[...]
 
 
The soap server contains a single function that writes the title and the
text of the article to a database :
 
<?php
function publier($article) {
 $conn=new mysqli('localhost','root','', 'mini_cms');
    $query = "INSERT INTO article (titre, texte) VALUES ('".
$article->titre ."', '". $article->texte ."')";
    $result=$conn->query($query);
    return $result;
}
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache 
$server = new SoapServer("desc.wsdl"); 
$server->addFunction("publier"); 
 
$server->handle(); 
?> 
 
The $article->titre variable points to the title (since it is a plain
simple xsd:string), but $article->texte points to an object, probably
because it is a complex type containing text and a sequence of elements.

The problem is, I don't know the name of that object's member variables,
and I don't know how to access them.
The web service works fine but instead of "<a href="foo.com">This</a> is
a text <strong>sample</strong>" in the database text column, I get
"Object id #3".
 
Does anyone know how to deal with complex types like that one ? I don't
want to parse the xhtml code, just to access the "texte" element as a
block and put it in the database...
 
 
Thanks in advance,
 
 
Guillaume
