Checking for the new meta-tags of:

I think you are better off to get web page content using PHP scripts and parse the files with REGEX.

If you Google around, I am sure you can find many sample PHP scripts that do most of what you want. This is very old technology and there is no need to reinvent the wheel parsing HTML data.

NAME

       CURLINFO_SSL_ENGINES - get an slist of OpenSSL crypto-engines

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_ENGINES,
				  struct curl_slist **engine_list);

DESCRIPTION

       Pass  the  address  of a 'struct curl_slist *' to receive a linked-list of OpenSSL crypto-engines supported. Note that engines are normally
       implemented in separate dynamic libraries. Hence not all  the  returned	engines  may  be  available  at  run-time.  NOTE:  you	must  call
       curl_slist_free_all(3) on the list pointer once you're done with it, as libcurl will not free the data for you.

PROTOCOLS

       All TLS based ones.

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.12.3. Available in OpenSSL builds with "engine" support.

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
