Hi there,

Building an XMLRPC server application.

The problem I am having is that I need to send html as a response, however the response is being recieved escaped using htmlspecialchars.

ie, this:

Code:
&lt;html&gt;

&lt;body&gt;

This is some text. 

&lt;script&gt; 

var thing="blah";

&lt;/script&rt;

&lt;/body&gt;

&lt;/html&gt;

becomes this in the response:

EDIT: Spaces put in artificially after ampersands to prevent the browser rendering them as entities.

Code:
&lt;?xml version="1.0" encoding="UTF-8"?&gt;

<methodResponse>

<params>

<param>

<value>

<struct>

<member>

<name>htmloutput</name>

<value>

<string>& lt;html& gt;& lt;body& gt;This is some text.& lt;script& gt; var thing=& quot;blah& quot;;& lt;/script& gt;& lt;/body& gt;& lt;/html& gt;</string>

</value>

</member>

</struct></value>

</param>

</params>

</methodResponse>

and once the client outputs the result, the script tag has also been stripped:

Code:
& lt;html& gt;& lt;body& gt;This is some text. var thing="blah";& lt;/body& gt;& lt;/html& gt;

My testing here is using the example lifted straight form the manual:

http://ellislab.com/codeigniter/user-gui...mlrpc.html

Except the server response is formulated as follows:

Code:
$string = '&lt;html&gt;&lt;body&gt;This is some text. var thing="blah";&lt;/body&gt;&lt;/html&gt;';

        $response = array (

                   array(

                         'htmloutput' => array($string, 'string')

                        ),

                 'struct'

                 );

Looking through the XML-RPC code I can see that htmlspecialchars is used, while not ideal I suppose I can get round that with htmlspecialchars_decode. Or alternativley alter the library so as to allow it to send html using cdata

I haven't yet found how the tags are being removed, which is somewhere in the client library.

So my question is ...

How the hell do I send html with javascript?

Or shoudl I RTFM a bit more ;-)?
