[Opensync-devel] gdata plugin: conversion from xmlcontact-doc to xmlcontact is failing

[Adenilson C. <cav...@gm...>]

Friends

The problem: when doing a sync, new contacts reported by google data
plugin generate this error:

#########################################################################################
Entity: line 1: parser error : Start tag expected, '<' not found
ERROR: Could not parse XML.
#########################################################################################

By grep'ing the source code, I identified the source of this error
message in opensync_xmlformat.c:osync_xmlformat_parse.

Initially, I thought that when I create an OSyncXMLFormat object with
'osync_xmlformat_parse' was triggering this error. But later
inspection confirmed that it is not the case.

Besides, the XML text used to create this object validates using
xmllint and xmlformat-contact schema.

Reading the traces, I uncovered that this error is happing when
opensync does the conversion from xmlformat-contact-doc to
xmlformat-contact, like bellow:

#########################################################################################

The complete log is available here: http://pastebin.com/m301cd82b

And the source code of gdata plugin is available here:
http://repo.or.cz/w/gdataplugin.git

I based the code of creating the change in file-sync plugin, with the logic of:
- create an OSyncXMLFormat object from raw XML representation of
google contact (converted to osync xml format);
- create an OSyncData object from the first object;
- create an OSyncChange object from the later and report the change.


I'm probably making misuse of the opensync API, but I'm out of clues.
Anyone have an idea of what is missing here?


Best regards
