| Subject: | json2xml chokes on Google AJAX Search API output |
When trying to convert JSON output from Google AJAX API to XML using the
xml2json method, I get an error message as follows:
Invalid data for key: responseDetails
Here is the dump from my program when I enable debug mode:
Converting json to obj using JSON::Syck at ./search.pl line 72
Key type for responseDetails is: (value seems to be ) at
/kunden/homepages/29/d87905022/htdocs/lib/perl5/XML/XML2JSON.pm line
701, <STDIN> line 1.
Invalid data for key: responseDetails
The conversion to XML works just fine when using the XMLout method of
the XML::Simple class (it is used in Google::Data::JSON class).
I attached a copy of the Google's JSON response. You can see a live copy
by running:
curl "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=perl"
