Hello, since I have not found anything on CardDAV related/written in/for FreePascal/Lazarus, (haven't googled with Delphi keyword thou)
I'd like to send out some smoke signals, asking which way would the support for this kind of interaction (dare not call it a protocol) would be best fitting into FreePascal/Lazarus world. CardDAV itself is an extension of WebDAV and itself has its own RFC (RFC6532). I myself am trying to write a client connecting via CardDAV to a compatible server (built into my CRM, eGroupware) to request search and read addressbook entries. (it was the developers of the CRM in question indicated to me that XMLRPC is dead and support for it will be removed when they get a chance - that's why I'm doing this.) So far I got as far as copy/pasting example XML from the RFC and got a valid response from server, using THTTPSend from Synapse. http://wiki.freepascal.org/XML_Tutorial (and particularly the second XML2Tree procedure from http://wiki.freepascal.org/XML_Tutorial#Populating_a_TreeView_with_XML, with some mod of mine to not pass a TTreeView but a TTreeNodes object into it instead) came in handy to understand the structure of it. There are certain advantages of CardDAV over XMLRPC, which this post is too short to contain ;) I intend to keep it very simple at first, as it's enough for my purpose, to the point that the XML elements+attributes would be coded just as string concatenating operations and validated using TXMLDocument from dom.pas. Seems like the more complicated elements of DOM level 3 will need DOM.pas modifications too. But I'd like to know, if there is interest in making it 'more sentient', e.g. as a TDataSource/TDataSet descendant directly talking to (reading, at first) DOM.pas's TXMLDocument/TDOMDocument, then to a THTMLSend or any such class of your liking? Please let me know your thoughts :) Kind Regards Lukasz _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
