    <title>Using Google Documents List Data API</title>

    <para>
        The Google Documents List Data API allows client applications to
        upload documents to Google Documents and list them in the form of
        Google Data API ("GData") feeds. Your client application can request
        a list of a user's documents, and query the content in an existing
        document.
    </para>

    <para>
        See
        <ulink url="http://code.google.com/apis/documents/overview.html">http://code.google.com/apis/documents/overview.html</ulink>
        for more information about the Google Documents List API.

        <title>Get a List of Documents</title>
        <para>
            You can get a list of the Google Documents for a particular user by using
            the <code>getDocumentListFeed</code> method of the docs
            service. The service will return a
            <classname>Zend_Gdata_Docs_DocumentListFeed</classname> object
            containing a list of documents associated with the authenticated
            user.

$service = Zend_Gdata_Docs::AUTH_SERVICE_NAME;
$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);
$docs = new Zend_Gdata_Docs($client);
$feed = $docs->getDocumentListFeed();
]]></programlisting>

        <para>
        The resulting <classname>Zend_Gdata_Docs_DocumentListFeed</classname> object
        represents the response from the server. This feed contains a list of
        <classname>Zend_Gdata_Docs_DocumentListEntry</classname> objects
        (<code>$feed->entries</code>), each of which represents a single
        Google Document.

        <para>
            You can create a new Google Document by uploading a word
            processing document, spreadsheet, or presentation. This example
            is from the interactive Docs.php sample which comes with the
            library. It demonstrates uploading a file and printing
            information about the result from the server.

            The full-text query string is used to search the content of all
