Question

I have a question about “&” symbol:

I have an return url in this format:

http://localhost/index.php?task=payment_return&id=113&token=750ac376e9ee1f6e87eba80c409005c4

I set it to XML in my PHP function, inside “url-retorno”:

private function XMLUrlRetorno() {
    // $msg = '<url-retorno>' . $this->getData('url_retorno') . '</url-retorno>';
    $msg = '<url-retorno>' . str_replace('&', '&amp;', $this->getData('url_retorno')) . '</url-retorno>';
    return $msg;
}

Ok, but the problem is the “&”, if my url are written in this format:

http://localhost/index.php?task=payment_return&id=113&token=750ac376e9ee1f6e87eba80c409005c4

Or

http://localhost/index.php?task=payment_return&id=113&token=750ac376e9ee1f6e87eba80c409005c4

I get this error from XML:

error: Unexpected end of file after url-retorno

I have tried with htmlspecialchar, with str_replace(‘&’, ..) and again error..

What to do, if ‘url-retorno’ have not “&” it’s working propertly, but if have, not?

The XML send:

Just use the cdata tag in your xml

 <![CDATA[
       Your url with & in it
     ]]>

This should look like this in your code and is totally xml conform.

    private function XMLUrlRetorno() {
        $msg = '<url-retorno><![CDATA[' . $this->getData('url_retorno') . ']]></url-retorno>';
        return $msg;

}
