Works good with SOGo, SabreDAV fix for simplify() method

[user678]

Hi,

SOGo catalog list for simplify:

<?xml version="1.0" encoding="utf-8" ?> 
- <D:multistatus xmlns:ap="http://apache.org/dav/props/" xmlns:D="DAV:">

  </D:propstat>

produces this output:

SabreDAV returns list folders in following format:

simplify() returns empty node. You may add the following fix:

    private function simplify($response, $include_vcards = true)
    {
        $response   = $this->clean_response($response);
        $xml        = new SimpleXMLElement($response);

        $simplified_xml = new XMLWriter();
        $simplified_xml->openMemory();
        $simplified_xml->setIndent(4);

        $simplified_xml->startDocument('1.0', 'utf-8');
            $simplified_xml->startElement('response');

                foreach ($xml->response as $response)
                {
                    if (preg_match('/vcard/', $response->propstat->prop->getcontenttype) || preg_match('/vcf/', $response->href))
                    {
                        $id = basename($response->href);
                        $id = str_replace('.vcf', null, $id);

                        if (!empty($id))
                        {
                            $simplified_xml->startElement('element');
                                $simplified_xml->writeElement('id', $id);
                                $simplified_xml->writeElement('etag', str_replace('"', null, $response->propstat->prop->getetag));
                                $simplified_xml->writeElement('last_modified', $response->propstat->prop->getlastmodified);

                                if ($include_vcards === true)
                                {
                                    $simplified_xml->writeElement('vcard', $this->get_vcard($id));
                                }
                            $simplified_xml->endElement();
                        }
                    }
                    else if (preg_match('/unix-directory/', $response->propstat->prop->getcontenttype))
                    {

                        $url = str_replace($this->url_parts['path'], null, $this->url) . $href;
                        $simplified_xml->startElement('addressbook_element');
                            $simplified_xml->writeElement('display_name', $response->propstat->prop->displayname);

                        }

        $simplified_xml->endDocument();

        return $simplified_xml->outputMemory();
    }

The 'else // fix here' is not a good enough condition to be consider as a vcard list.
The check should :

else if (preg_match('/x-vlist/', $response->propstat->prop->getcontenttype))

However the extension is not the same now ie: '.vlf'
So it still won't work but it is a start.

[user678]

It is possible only to check <card:addressbook /> empty node?

[hhfeuer]

i've fixed it like that:
-else if (preg_match('/unix-directory/', $response->propstat->prop->getcontenttype))
+else if ($response->propstat->prop->resourcetype->addressbook->getName()=="addressbook")

and in
private function clean_response($response)
{
$response = utf8_encode($response);
$response = str_replace('card:', null, $response);
$response = str_replace('D:', null, $response);

Maybe a combination of preg_match and getName would be better?

I implement it in commit
